Motor Control

Build and deploy motor control applications using PMSM

Implement open-loop or closed-loop FOC (field-oriented control) techniques for sensor-based and sensorless position applications using PMSM (permanent magnet synchronous motor).

The support package includes reference examples that help you build and deploy motor control applications on STM32 hardware boards (with Motor Control Blockset™ and Embedded Coder^®).

Featured Examples

Open-Loop Control of 3-Phase AC Motors Using STM32 Processor Based Boards

Uses open-loop control (also known as scalar control or Volts/Hz control) to run a motor. This technique varies the stator voltage and frequency to control the rotor speed without using any feedback from the motor. You can use this technique to check the integrity of the hardware connections. A constant speed application of open-loop control uses a fixed-frequency motor power supply. An adjustable speed application of open-loop control needs a variable-frequency power supply to control the rotor speed. To ensure a constant stator magnetic flux, keep the supply voltage amplitude proportional to its frequency.

Field-Oriented Control of PMSM with Hall Sensor Using STM32G4xx Based Processors

Implements the field-oriented control (FOC) technique to control the speed of a three-phase permanent magnet synchronous motor (PMSM). The FOC algorithm requires rotor position feedback, which is obtained by a Hall sensor.

Hall Offset Calibration for PMSM with STM32 Processors

Calculates the offset between the rotor direct axis (d-axis) and position detected by the Hall sensor. The field-oriented control (FOC) algorithm needs this position offset to run the permanent magnet synchronous motor (PMSM) correctly. To compute the offset, the target model runs the motor in the open-loop condition. The model uses a constant (voltage along the stator's d-axis) and a zero (voltage along the stator's q-axis) to run the motor (at a low constant speed) by using a position or ramp generator. When the position or ramp value reaches zero, the corresponding rotor position is the offset value for the Hall sensors.
