FAQ
Why use STM32 for BLDC motor control?
STM32 MCUs provide advanced timers, synchronized ADCs, DMA, and motor-control peripherals that enable precise PWM generation, current sampling, and real-time control.
Is the controller completely sensorless?
Yes. Rotor position is estimated using Back-EMF techniques, eliminating the need for Hall sensors or rotary encoders.
Can the controller regulate motor current?
Yes. The firmware includes current feedback loops to limit phase current, improve torque stability, and protect the power stage.
Which communication interfaces can be added?
UART, CAN, SPI, I²C, USB, RS-485, PWM inputs, and other interfaces can be integrated as required.
Will the PCB be optimized for manufacturing?
Yes. Layouts follow best practices for DFM, controlled high-current routing, thermal management, and EMC considerations.
What deliverables are included?
Schematic, PCB layout, Gerber files, BOM, assembly drawings, and firmware according to the selected package.
Can you customize the control algorithm?
Absolutely. Firmware is tailored to your motor characteristics, startup requirements, torque profile, and operating conditions.
