The purpose of this application note is to illustrate a software-based implementation of sensorless, field oriented control for permanent magnet synchronous motors using Microchip digital signal ...

When used in an appliance, a permanent magnet synchronous motor (PMSM) provides very good efficiency because of its constant rotor magnetic field, which is produced by a permanent magnet on the rotor.

motor control based on a six-step commutation sequence; detection of the magnetic angle of the rotor, to perform the commutation at the correct angle (each step corresponds to an angle of 60 degrees); ...

Designers can expect environmental demands to continue to drive the need for advanced motor control techniques that produce energy efficient air conditioners, washing machines and other home ...
