Product overview
Product description
siliXcon brushless motor controllers are a key component of a system that effectively controls three-phase motors. They are intended to operate with low-voltage DC power sources and are available in various voltage options, providing versatility and flexibility. Due to these features, siliXcon motor controllers are primarily used in battery-powered vehicles that require compact dimensions. Key features of siliXcon motor controllers include:
- High power density: Advanced technology and an emphasis on efficient heat dissipation from the most stressed areas allow us to maintain the control unit's dimensions as small as possible.
- Modularity: Individual blocks of the control unit are designed as modules that are shared among various controller models and variants. This provides users with a high degree of flexibility, and transitions between models do not pose complications.
- High dynamics: An extremely fast control loop for phase currents ensures precise current control and very rapid response to changes in control signals.
- Advanced protective features: Thanks to precise control of phase current and temperature control at critical points, the controller is robustly protected against overcurrent and overheating.
- VCU (Vehicle Control Unit): Integration of a high-performance microprocessor allows the implementation of vehicle control functions directly into the controller, thus saving installation space and end-application costs.
The controller is primarily designed to drive an electric motor with permanent magnets. Two standard FW applications LYNX and OPHION can be loaded into the controller.
SC controller
siliXcon 11.5kW brushless motor controller is a very compact and lightweight controller featuring flying wires for signals and power terminals. Its innovative thermal management allows it to minimise dimensions and weight while maintaining its maximal power output. Low-performance e-motorbikes are the target applications for this controller.

- HW configuration
Usually defines a variant of the power stage, occasionally can indicate a special version of the product's PCB.
The particular controller's voltage variant usually uses different MOSFETs based on the given voltage range.
Available versions are:
- 24: Standard version of the controller. Indicates 24 MOSFETs in the power stage.
Defines variant of the powering interface
Available versions are:
-
d: Standard version of the controller. This version does not have any additional features.
-
e: Special version of the controller, equipped with the capacitors precharge circuit.
Precharge
This feature enables automated capacitor precharging via an internal power source with limited current, effectively eliminating excessive inrush current when connecting the battery.
This feature requires the usage of a battery contactor controlled by the motor controller. The battery's positive terminal is connected to the controller's logic (controller turned ON), and the internal power source charges the capacitors with the defined current. Once the capacitors reach the required voltage level, the main battery contactor closes, connecting the battery's positive terminal directly to the controller.
The required precharge voltage level and contactor coil operating voltage can be set by SW parameters according to the particular use case and used components.
Defines variant of the communication interface
Available versions are:
Defines supported motor position sensors. More infornation about the particular motor postion sensor interface can be found in this section.
Available versions are:
-
a: Standard version of the controller. Supports 3 Hall and Sin/Cos motor position sesnors.
-
r: Special version of the controller. Supports resolver motor postion sensor.
Defines voltage operation range of the controller. Detailed technical specifications can be found in this section.
The higher the limit voltage range, the better the protection against overvoltage. However, as the voltage range increases, the MOSFETs' Rdson also increases.
Available versions are:
- 10: Standard version of the controller. The absolute voltage limit is 100 V.
- 08: Special version of the controller. The absolute voltage limit is 80 V.
Defines current measurement range of controller.
The higher the current measurement range, the better the protection against overcurrent. However, as the current measurement range increases, the resolution of the current measurement decreases.
Available versions are:
- 40: Standard version of the controller. The measuring range is 400 A.
