Controller Firmware

Firmware for siliXcon motor controllers consist of two major part:

  • Motor control algorithm
  • Application

The application is responsible for the whole system behaviour. It transfers inputs to outputs.

The algorithm is responsible for controlling the motor. Protecting the motor, battery, and the controller.

The application and the algorithm is hardware independent. This mean, you can scale your a project without any problem.

Custom Application

It is not possible to have controller with behaviour, that suit to all use-cases. This is why we can provide you completely custom solution.


All controllers support our scripting language. Using these script you can customise existing application or write your own from ground up.


  • Ophion is an FW application designed for generic usage with electric motor drives.
  • It can be used in a wide range of applications from a very simple pump control to a complex position servo drive.
  • It is an HW-independent application that can be uploaded to the whole siliXcon’s controllers portfolio.
  • It has several predefined control modes which cover a lot of field of operation, which allows very fast deployment.
  • Ophion can also exploit all available motor control modes to enhance its potential even more.


  • LYNX is a universal control system offering off-the-shelf complete solutions for traction systems.
  • It has several configurable logical inputs, which can be used for gathering data from external components (throttle, brake, pas, switches, etc). These signals are processed inside the system and define how the motor reacts, according to the parametrisation of the LYNX.
  • This approach can eliminate a need for a VCU (vehicle control unit) – controller with this FW is capable to process most of the needed signals.
  • It is an HW-independent application that can be uploaded to the whole siliXcon’s controllers portfolio.
