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
The "Typical competition" column is industry-agnostic — averaged 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, …) and may beat the average in their niche. The matrix is scoped to our motor controllers, not to siliXcon as a whole.
Comparison matrix
Drive & motor control
| Feature | Typical competition | siliXcon |
|---|---|---|
| Motor control algorithm | A single algorithm hard-wired into the product (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. |
| 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 inductances down to units of µH and speeds up to 300 krpm, with native 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 typically ends with hardware replacement. | Wide sensor support with automatic fall-back to sensorless and runtime self-diagnostics. |
| 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. |
| Command dynamics | Pre-computed slopes, forced filtering and ramping, artificial limits around the sensorless region. | Real-physics derating only — nothing is pre-computed. Every command is executed as fast as the hardware allows, with full dynamics through the sensorless region. |
| Servo drive | Traction or industrial-servo product lines, rarely both. Servo-grade precision typically requires a dedicated, lower-power product. | Servo-grade speed, torque and position control on the same controller — full traction-class power electronics combined with precise low-speed and standstill behavior. |
| Drive / command modes | A single, low-level command interface — typically just duty cycle for BLDC products or a torque setpoint for FOC products. Everything else is the integrator's problem. | 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. |
| 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 routinely damage the inverter. | Always seamless four-quadrant operation — motoring, generating, back-drive and engage/disengage at any operating point. |
| Overload handling | Hard cut-offs at fixed thresholds — or no derating at all, with the fault propagating up to the power stage. | 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. |
Power, sizing & protection
| Feature | Typical competition | siliXcon |
|---|---|---|
| Honest, measured ratings | Exaggerated, short-burst marketing numbers; "power" is typically just U × I on paper, and voltage/current/efficiency figures are often single optimistic snapshots or simply estimated from component datasheets. | Every rating is measured on the bench, in our lab, under real load — voltages, currents, efficiency and power, characterized 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 uncompromising 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. |
Configuration & 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. | Multiple CAN and UART buses, general-purpose digital and analog I/Os, dedicated contactor / pre-charge outputs, with the communication protocol selectable in firmware and changeable after-sales. |
| Application & customization | Fixed, industry-specific firmware preloaded by the vendor; deep changes require a different product or are simply not offered. | Configurable application platform with hundreds of ready-made modules (see below). For unique requirements we deliver dedicated custom (OEM) applications on the same hardware. |
| 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. |
Diagnostics, lifecycle & safety
| 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. |
| 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. 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 lists below are just a sample from our pool of predefined modules, accumulated over 15+ years of e-powertrain experience across many industries — and the catalogue keeps growing with every project.
- 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. Multiple controllers can synchronize axes precisely in a peer-to-peer fashion, with no central master unit required — any controller in the system can act as the single point of contact to receive drive commands and aggregate telemetry for the host.
- External device integration out of the box — displays, light outputs and GPIO peripherals.
- 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.
- Predefined control modes (speed, torque, position) ready to use without any programming.
- 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.
- Starter-generator operation with configurable cranking sequence (pullback, cranking, pause, retry) and overvoltage protection.
- Redundant input signals, drivetrain self-monitoring and runtime fault detection across the whole signal chain.
- 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.
- Persistent maintenance counters — motor-hours, start cycles, service intervals — for predictive maintenance and compliance.
- Acoustic feedback through the motor itself — arming, disarming, throttle errors and other system events without any extra hardware.
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 an evaluation unit to a high-power production unit and your parameters, features, CAN map and integration code come with it. Competitors typically force you onto a different product line every time the power class changes.
- One set of tools for the entire fleet. SWTools, siliWatch, the diagnostic report, the parameter editor, this 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 — and inherit every platform-level improvement automatically.
- An ecosystem, not just an inverter. siliXcon accessories — BMS, displays, IO expanders — speak the same CAN dialect, share the same parameter tree, and are configured and updated through the same tools. Multi-controller VCU and inter-axis synchronization are native capabilities, not glue firmware.
- Long-term, after-sales evolution. Fleets already in the field receive new features, bug fixes and even protocol changes through normal firmware updates — for years after shipment.
Competitors typically sell products. We deliver a platform — and the controller is just the part of it you can hold in your hand.
