Product overview

Product description

siliXcon 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:

  1. 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.
  2. 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.
  3. High dynamics: An extremely fast control loop for phase currents ensures precise current control and very rapid response to changes in control signals.
  4. 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.
  5. 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.

SX controller

SX motor controller is a compact and robust solution featuring a single signal connector (superseal 1.0). With an impressive capability to deliver up to 280 A rms, this controller is designed to power small e-motorbikes and larger e-scooters. Its M6 power terminals, crafted from brass, ensure minimal power losses. This versatile controller is well-suited for various applications, including automotive, marine, aerospace, and more, with a primary emphasis on high-series production.
