Abstract
This technical essay deals with the control of a permanent magnet synchronous motor. We discuss electromagnetism in some detail. We derive the classical model of a permanent magnet synchronous machine and use this model to evaluate several control strategies. Field-oriented torque control and field-oriented speed control are introduced. Control without a sensor for the position of the rotor is mentioned briefly. A discussion of issues arising when implementing field-oriented control in software, the circuit of a power stage and some measurements conclude the treatise.

Notes
- 1.
Named after Edith Clarke, the first female University professor in Electrical Engineering in the United States.
- 2.
Named after Robert H. Park, who first formulated a model of a synchronous machine in rotor coordinates.
- 3.
The windings of permanent magnet machines which have a rotor with a core that is not cylindrical exhibit inductances which depend on the position of the rotor.
- 4.
Also known as squirrel cage fan.
