Sensorless Field Oriented Control for PMSM Motors
Permanent Magnet Synchronous Motors (PMSM) are often considered “exotic” or useful only for appliance applications plus perhaps a few niche markets. The reality is that PMSM motors have been gaining significant traction in a number of widely diversified applications. Like all motor types they have their pros and cons.

Advantages of PMSM motors include:

Cons have been the cost of the motor and the cost and complexity of control. The PMSM motor consists of a magnetic rotor and wound stator construction. Having no bulky copper rotor windings saves weight, size and the cost of copper but adds the expense of magnets. This expense may be reduced in the future when key patents expire for the underlying rare earth-based magnet technology. The cost of control is reduced by employing low cost dsPIC Digital Signal controllers and (optionally) removing expensive sensors by incorporating back-EMF to calculate rotor position. Microchip has addressed the complexity issue by providing free libraries and dedicated motor control development tools.
