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.

6 | Status LED |
7 | Signal connector - Ampseal |
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.
- New version
- Old version
There are two jumpers with 4 pins in total. The jumpers' localization and function are depicted in the picture below.
There are two jumpers with 6 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 variants are in stock.

Details
Complete MPN:
Main PCB assembly variant:
- 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".
- Powering on method: The device offers several powering methods, defined by
the combination of the following items. For details see powering circuit's detailed specification.
- Internal Fuse
- Flip-flop / One button control
- Constant ON
- Power supply option: Defines isolated supply voltage level on signal connector pin 35.
- CAN terminator: The device has a selectable internal 120-ohm termination resistor. A detailed CAN interface scheme can be found in the CAN communication interface.
- Connected grounds: It is possible to connect two grounding potentials together by the internal jumper.
Finish 1 and Finish 2:
- Signal connector: Defines signal connector options.
- Power terminals: Defines used power Terminals.
- Housing: Defines housing option.
LED status indicator
The LED status indicator informs about the current state of the motor controller according to table below.
LED color | LED state | Controller condition |
---|---|---|
None | Permanently turned OFF | The controller is not powered on. |
Red | Permanently turned ON | The controller is turned on and the power stage is not ready. The controller indicates that any of the protections are active. |
Red | Blinking | The 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. |
Green | Permanently turned ON | The controller is turned on and the power stage is ready (the motor is not driven). |
Green | Blinking | The 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. |
Blue | Permanently turned ON | The controller is turned on and the power stage is ready and the motor is driven. |
Purple | Permanently turned ON | The 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. |
Yellow | Permanently turned ON | The 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.
Thermal grease
- to improve cooling of the controller, you should apply thermal grease to the mounting area of the controller. Example: Electrolube HTC, AG termopasty HPX
