PMSM Field Oriented Control


Design Considerations

Permanent Magnet Synchronous Motors (PMSM) are similar to Brushless DC motors (BLDC). PMSM are rotating electrical machines that have a wound stator and permanent magnet rotors that provide sinusoidal flux distribution in the air gap, making the BEMF inform a sinusoidal shape. The construction of the stator and rotor can provide lower rotor inertia and high power efficiency and reduce the motor size.

Depending on how magnets are attached to the rotor, PMSM motors can be classified into two types: surface PMSM (SPMSM) and interior PMSM (IPMSM). SPMSM mounts all magnet pieces on the surface, and IPMSM places magnets inside the rotor. 

Application Notes

Development Kits/Boards

  • The CY8CKIT-037 is used for PSoC 4 solution evaluation for motor control application. The kit supports BLDC (BrushLess Direct Current) motors, PMSM (Permanent Magnetic Synchronous Motors) and stepper motors. We provide example projects including single-shunt and sensorless FOC (Field Oriented Control), sensored BLDC control, sensorless BLDC control and stepper motor control example projects.
