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

  • This kit enables engineers to evaluate Cypress's PSoC family of devices for motor control applications. Based on this kit, customers can create control solutions for three dominant motor types: permanent magnet synchronous motor (PMSM), stepper, and brushless DC (BLDC).

  • The PSoC 4 Pioneer Kit is an easy-to-use and inexpensive development platform enabling you to create unique designs with the flexibility of PSoC®4. Featuring the PSoC 4200 device family, this kit gives you the power of an ARM Cortex-M0 combined with the fully customizable analog and digital fabric of the PSoC in the palm of your hands.
