How do siliXcon controllers compare to the competition?
Below is a feature-by-feature comparison matrix that we put together in response to a recurring customer question: "How are you different from the competition?". The right column reflects the engineering choices that have shaped our motor controllers over the last 15 years.
info
This comparison is specific to our motor controllers vs. competing motor controllers. Some of the listed strengths are general siliXcon traits, but the matrix below is scoped to the controller product, not to our company or ecosystem as a whole.
The "Typical competition" column is industry-agnostic — an average across the brushless controllers we have benchmarked over the years. Competing products usually specialize in a single industry (RC, EV, e-bike, industrial servo, drones, marine, …) while struggling outside it.
Individual competing products may, of course, do better than the average in any given row.
Comparison matrix
Drive performance & dynamics
| Feature | Typical competition | siliXcon |
|---|---|---|
| Command dynamics | Pre-computed slopes, forced filtering and ramping, artificial limits introduced around the sensorless region. | Derating is based on real physics only — nothing is pre-computed. Every command is executed as fast as the hardware allows, with full dynamics preserved through the sensorless region. |
| Engaging / disengaging | Drive can only be engaged when the motor is at standstill or already spinning along the command direction. Anything else can lead to catastrophic failure of the power stage. | Engage or disengage at any time, in any direction, at any RPM. Even a power cycle while the motor is spinning at nominal RPM is recovered seamlessly. |
| Back-drive / regen | Back-driven motors and sustained regenerative operation are not handled, and can lead to catastrophic failure of the controller. | Always seamless four-quadrant operation — motoring, generating, back-drive and engage/disengage at any operating point. |
| Sensorless mode | No torque at zero RPM, requires rotor pre-positioning, demands extremely sensitive startup tuning. | Near full torque at zero RPM, seamless startup, smooth go-through-zero at full dynamics, instant direction reversal — no pre-positioning, no startup tricks. |
| Motor control algorithm | A single algorithm hard-wired into the product (either FOC or BLDC); switching algorithm requires a different hardware SKU. | Three selectable algorithms on the same hardware: FOC for absolute precision down to zero speed, BLDC for robustness, and high-speed BLDC for extreme RPM. |
| Drive / command modes | A single, low-level command interface — typically just duty cycle for BLDC products or a torque setpoint for FOC products. Anything more sophisticated has to be built on top by the integrator. | 8+ runtime-selectable command mappings on the same firmware — from raw duty cycle and torque, through speed, position and slip control, all the way to full-vehicle command profiles. The same platform powers applications from large drones to industrial AGVs and EVs. |
| Supported motors | Tuned for a narrow window of motor parameters; high-RPM, low-inductance, IPM or reluctance motors usually require a different product (or are simply unsupported). | Drives virtually any 3-phase motor: PMSM (SPM/IPM), BLDC, ACIM, switched/synchronous reluctance; inrunner/outrunner; axial/radial flux. Handles motor inductances down to units of µH and shaft speeds up to 300 krpm, with native support for field weakening and reluctance-torque exploitation (MTPA). |
| Supported motor sensors | One or a few hard-coded sensor types; no automatic fall-back. A sensor malfunction in operation can lead to catastrophic failure. | Wide sensor support with automatic fall-back to sensorless and runtime self-diagnostics. |
| Overload handling | Hard cut-offs at fixed thresholds — or no derating at all, which can lead to catastrophic failure. | Always proportional, physics-based derating: temperatures, currents, voltages and RPM are continuously combined inside the protection system, so the controller gracefully reduces output instead of dying. |
Sizing, ratings & protection
| Feature | Typical competition | siliXcon |
|---|---|---|
| Power rating | Exaggerated, short-burst marketing numbers; "power" is typically just calculated as U × I on paper, never actually measured. | Every rating is measured on the bench, in our lab, under real load — and only then put into the datasheet. The numbers you see are the numbers we are willing to stand behind. |
| Datasheet honesty | Voltage, current and efficiency figures are often single optimistic snapshots — or simply estimated from component datasheets and copied into the spec sheet. | We measure, characterize and publish real numbers across the operating envelope. We don't guess; if a value is in the datasheet, it has been verified on real hardware. |
| Physical size | Compromised by the "enlarge-with-rating" rule of thumb; the mechanical envelope grows roughly linearly with rating because the design has no margin without bulk. | Cross-platform engineering and an aggressive protection system let us deliver the same rating in roughly ¼ of the size of comparable competition. |
| Failure protection | Limited or single-layer protection; an unexpected event (short, overvoltage, undervoltage, sensor glitch) can take the whole power stage with it. | Full ultra-fast short-circuit protection at the gate-driver level, combined with multi-layer over- and under-voltage protection and continuous self-diagnostics. Layered so that no single fault — electrical, thermal or sensor — should ever cause catastrophic failure. |
Configurability & integration
| Feature | Typical competition | siliXcon |
|---|---|---|
| Parametrization | Limited, fixed set of configurable parameters; non-trivial changes require vendor support. | 500+ exposed parameters covering motor, drive, protection, application and connectivity layers — fully accessible to the integrator. |
| User inputs | Fixed input type per product family — analog-only, PWM-only, or CAN-only. | Same hardware accepts analog (potentiometer, 0–10 V, 4–20 mA), digital (FWD/REV/STOP, switches), servo PWM, and CAN/UART commands — selectable in firmware. |
| Connectivity | Limited interface set fixed by the hardware; a single industry-specific protocol baked in. | Rich hardware interfacing options — multiple CAN and UART buses, general-purpose digital and analog I/Os, and dedicated contactor / pre-charge outputs — with the communication protocol selectable in firmware and changeable after-sales. |
| Application layer | Fixed, industry-specific firmware image preloaded by the vendor. | Configurable application platform with hundreds of pre-existing features, ready to be combined into a software-managed vehicle. |
| Distributed vehicle control | A central VCU/master unit is required to coordinate multiple axes; remove it and the vehicle stops working. | Multiple controllers synchronize axes precisely in a peer-to-peer fashion — no master unit needed. Any controller in the system can act as the single point of contact to receive drive commands and aggregate telemetry for the host. |
| Accessory integration | Third-party BMS, displays and peripherals patched in by the integrator over generic CAN. | Native, plug-and-play integration with siliXcon accessories — BMS, displays, IO expanders and more — sharing the same parameter tree, diagnostics and update channel as the controller itself. |
| Servo capability | Traction-only or servo-only product lines, rarely both. | Speed, torque and position control modes available on the same controller — servo-grade precision combined with full traction-class power electronics. |
Diagnostics, lifecycle & support
| Feature | Typical competition | siliXcon |
|---|---|---|
| Diagnostics & telemetry | Limited error codes, often no live insight into the controller's state. | Live telemetry via siliWatch, full diagnostic report, per-protection derating breakdown, and detailed event/error logs. |
| Firmware updates | Update procedures often require returning the unit or specialized service tooling. | Remote firmware and parameter updates over standard interfaces — supported as a normal after-sales workflow even on units already deployed in the field. |
| Documentation | Datasheet plus an integration guide, with most know-how locked behind support tickets. | This portal: full firmware, hardware and software documentation publicly available, including FAQs, guides and an AI assistant. |
| Customization | One-size-fits-all; deep changes require a different product or are simply not offered. | Standard applications cover most cases; for unique requirements we develop dedicated custom (OEM) applications on the same hardware platform. |
| Functional safety posture | Safety is often an afterthought — single-layer protection, undocumented failure modes, no traceable design rationale. | Protection-system-first design philosophy: every feature is built around the protection envelope rather than bolted on. FMEA, design-rationale and safety-relevant test artifacts are available under NDA for OEM and integration projects that require them. |

Application-level features
The matrix above shows where we stand strong at the fundamentals. But the value added does not stop at the inverter level — on top of that, the same platform brings a whole catalogue of ready-made application-level modules that competitors typically expect you to build. Some are already wired up in our stock applications; the rest are building blocks we combine into a tailored OEM firmware in a matter of days — no ground-up development.
The list below is just a sample from our large pool of predefined modules, accumulated over 15+ years of e-powertrain experience across many industries — and it keeps growing with every project we take on:
- Full vehicle-controller (VCU) replacement — performance maps, acceleration / braking / regenerative-braking control, and up to 9 user profiles for per-rider or per-operator tuning.
- External device integration out of the box — displays, light outputs, GPIO peripherals and master-slave / multi-controller wiring.
- Redundant input signals, drivetrain self-monitoring and runtime fault detection across the whole signal chain.
- Predefined control modes (speed, torque, position) ready to use without any programming.
- Persistent maintenance counters — motor-hours, start cycles, service intervals — for predictive maintenance and compliance.
- Automatic driver re-initialization after errors, critical for aerial and other safety-sensitive applications.
- Emergency-stop logic with controlled ramp-down braking, position hold and propeller docking.
- Acoustic feedback through the motor itself — arming, disarming, throttle errors and other system events without any extra hardware.
- Starter-generator operation with configurable cranking sequence (pullback, cranking, pause, retry) and overvoltage protection.
- Traction control — wheel-slip detection and proportional torque reduction for reliable acceleration on low-grip surfaces.
- Anti-slip differential — multi-controller torque coordination across driven wheels to suppress single-wheel spin without a mechanical diff.
- Torque vectoring — independent torque distribution between wheels for improved cornering, stability and steering response.
- Flywheel emulation — software-tunable rotational inertia of the drivetrain for natural drive feel or precise dynamic shaping.
- Pure-peripheral mode — every IO and motor-control feature exposed through the Driver API for full external VCU control, with optional CANopen for industrial integration.
- Quick-setup pad for initial configuration without any PC tooling.
And on top of all that — it's a platform
The single most important difference is not in any individual row above. It is the fact that every siliXcon controller — from the smallest unit up to the largest 800 A class — is part of one coherent motor control platform: shared firmware codebase, shared parameter tree, shared tooling, shared documentation, shared protection philosophy.
In practice, that means:
- One firmware, many controllers. The same application firmware runs across the entire hardware range. Move a project from a small evaluation controller to a high-power production unit and your parameters, features, CAN map and integration code come with it — no re-engineering, no re-learning a new product.
- Scale up or down without switching vendor. Hardware is sized to the vehicle; the application logic stays the same. A typical competitor forces you onto a different product line (with a different toolchain, different protocol, different quirks) every time the power class changes.
- One set of tools for the entire fleet. SWTools, siliWatch, the diagnostic report, the parameter editor, this documentation portal and the AI assistant work identically across every device we ship.
- OEM firmware as a first-class citizen. Our custom (OEM) applications live inside the same platform — not as forks — inheriting every protection, control and connectivity feature by default and benefiting from every platform-level improvement we ship.
- A vehicle, not just an inverter. Multi-controller VCU architectures, software-managed-vehicle, virtual axis coupling and inter-controller synchronization are native platform capabilities. The platform is designed for the whole drivetrain, not just for spinning a single motor.
- Distributed vehicle control with native accessories. The platform extends beyond the controller to siliXcon accessories — BMS, displays, IO expanders — which speak the same CAN dialect, share the same parameter tree and are configured, diagnosed and updated through the same tools. No glue firmware between subsystems.
- Long-term, after-sales evolution. Because everything is on one platform, fleets already in the field can receive new features, bug fixes and even protocol changes through normal firmware updates — for years after the unit was shipped.
Competitors typically sell products. We deliver a platform — and the controller is just the part of it you can hold in your hand.
