36V/144W BLDC Motor Controller

Overview

This design features a 32-bit MCU optimized for field-oriented control (FOC) of a single BLDC motor. The MCU includes a best-in-class floating point unit (FPU) and built-in peripherals for motor control, allowing for a compact and cost-effective motor controller. The system is powered off a standard 24VDC input and receives precise position feedback from an inductive position sensor.

System Benefits​:

  • Features an inductive position sensor, a highly integrated contactless sensing device for precise motor control.
  • Supports motors from 12V up to 36V, with a maximum current of 4A (144W)
  • MCU integrates a 3-channel programmable gain amplifier (PGA), eliminating the need for external current sense amplifiers (CSAs).
