25 kW brushless motor controller is a compact and robust motor controller featuring a single signal connector (Ampseal) and M6 power terminals for battery and motor power cables. Its innovative thermal management allows it to minimize dimensions and weight while maintaining its maximal power output. Midsize e-motorbikes or small e-cars are the target applications for this controller.

Product editions​

The SL series is available in different editions, each tailored to specific application requirements:

  • SL controller — Standard edition � maximum working voltage 84 V.
  • SL MV — Middle voltage edition � modified for working voltages up to 118 V.
  • Raptor L Fan — Optimized for airborne applications with active air cooling.

Product variants​

The Manufacturer Part Number (MPN) completely specifies the product type and version. When combined with the Firmware Identifier (Basename), it can serve as the ordering code. The MPN is made up of different sections, which are explained in the table below. Typically, only the standard variant is in the stock.

warning

  • The pricing for non-standard MPN is individual. Please contact siliXcon for quotes.

  • For sample orders, selecting a non-standard product variant may result in increased pricing and extended lead times compared to standard samples.

  • Power stage: Usually defines a variant of the power stage, occasionally can indicate a special version of the product's PCB.
  • Power features: Defines variant of the powering interface. See powering circuit's detailed specification and Controller powering methods.
  • Connectivity: Defines variant of the communication interface. See USB, CAN, UART.
  • Motor sensors: Defines supported motor position sensors. More information about the particular motor position sensor interface can be found in this section. General information about motor sensors can be found in Motor sensors chapter.
  • Voltage: Defines voltage operation range of the controller. Detailed technical specifications can be found in this section.
  • Current: Defines current measurement range of the controller.
  • Internal HW configuration: see section below

Internal HW configuration:

Internal HW configuration describes selectable modifications in hardware. Each item can be present (marked with 1) or absent (marked with 0). A 12-bit binary number is used for this description and is visualized in hexadecimal form. Not all the options are used, these items are marked as "Reserved".
