Product overview

SC controller

siliXcon 15 kW brushless motor controller is a very compact and lightweight controller featuring flying wires for signals and power terminals. Its innovative thermal management allows it to minimize dimensions and weight while maintaining its maximal power output. Low-performance e-motorbikes are the target applications for this controller.

Main PCB assembly variant:

sc-main-assembly

  • 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.

  • 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 stateController condition
Permanently turned OFFController is not powered up
Briefly turned ON and after a few sec OFFController is powered and fully functional
Permanently turned ONController indicates that any of the protections are active. Output current can be limited.
BlinkingController indicates an internal error and is blinking a 16-bit error code. Controller's power stage is deactivated

Accessories

Signal connector

Power connectors

  • Motor phase mating connector: Amass XT150-Main
  • Battery+ mating connector: Amass AS150-M Red
  • Battery- mating connector: Amass AS150-F Black

Set of mating connectors

siliXcon can provide a set of mating connectors for end-application prototyping. The signal JST connectors for the default variant (USB, CAN, UART10V, POWER, CNTRL1, CNTRL2, MSENS, DOUT) are precrimped with 10cm cables. Mating motor phases and battery connectors are included without wires. Please contact siliXcon customer support for more details.

Mounting screws

  • 4x M4 or M5 screw. M4 screws are through the heatsink, M5 screws have a thread in the heatsink. Refer to the SC 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.
