Product overview

SL controller​

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.

Signal part is connected via the signal connector - 7. Battery is connected to M6 terminals - 1, 2, as well as motor phases - 4. The controller should be installed by placing the mounting surface - 3 on a flat metal surface and securing it by four screws. Status LED - 6 indicates error states. USB-B programming connector is under the cover - 5.

Selectable jumpers​

SL controller can be equipped with two versions of the jumper board. Unfortunately, the board version is not reflected in the controller's MPN, and it is necessary to identify them by physical appearance.

Both versions' selectable jumpers are located under the USB cover.

There are two jumpers with 4 pins in total. The jumpers' localization and function are depicted in the picture below.

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.

  • 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".

LED status indicator​

The LED status indicator informs about the current state of the motor controller according to table below.

LED colorLED stateController condition
NonePermanently turned OFFThe controller is not powered on.
RedPermanently turned ONThe controller is turned on and the power stage is not ready. The controller indicates that any of the protections are active.
RedBlinkingThe controller is turned on and the power stage is not ready. The controller indicates an internal error and is blinking a 16-bit error code.
GreenPermanently turned ONThe controller is turned on and the power stage is ready (the motor is not driven).
GreenBlinkingThe controller is turned on and the power stage is ready (the motor is not driven). The controller indicates an error code of the common block.
BluePermanently turned ONThe controller is turned on and the power stage is ready and the motor is driven.
PurplePermanently turned ONThe controller is turned on and the power stage is ready and the motor is driven. The controller indicates that any of the protections are active and output current could be limited.
YellowPermanently turned ONThe controller is turned on and the power stage is ready (the motor is not driven). The controller indicates that any of the protections are active.

Power connectors​

  • mating connector: M6 cable lug 10 - 50 mm2 + M6 screw. Terminal thread length is 13 mm, maximum tightening torque is 10 Nm.

Mounting screws​

  • 4x M5 or M6 screw. M5 screws are through the heatsink, M6 screws have a thread in the heatsink. Refer to the SL controller drawing.
  • for through-hole mounting, minimum thread depth is 1.5 x screw diameter. Tightening torque depends on the material of the mounting base.
