PMSM Motor Controller with STM32F3, FOC & PFC

Droid Technologies designed and developed a high-power motor control system for a 1.5 kW PMSM (Permanent Magnet Synchronous Motor) used in a commercial blender.

The system consists of two custom electronic boards: a power conversion board and a motor control board. The power stage manages energy conversion and includes Power Factor Correction (PFC) for improved efficiency, reduced harmonic distortion, and stable operation under changing loads.

The motor controller is based on an STM32F3 MCU and uses the STM32 PMSM FOC Motor Control Software Development Kit (MCSDK / MC Library) for Field-Oriented Control. The firmware provides precise regulation of motor speed, torque, current, startup, and operating modes.

Droid Technologies delivered power electronics design, hardware and PCB development, embedded firmware, PMSM motor control, FOC implementation, PFC integration, and system testing.

Key features and engineering scope:

• 1.5 kW PMSM motor control
