Self-Sensing Methods from MEMs to Solar Aircraft Motors

Yves Perriard, Miroslav Markovic, Omar Scaglione

In order to control the speed and/or position of permanent magnet (PM) motors, they require position sensors. Basically, the auto-commutation needs 3 sensors for a 3-phase motor. In micro-motors, as there is no space for the sensors, self-sensing must be u ...
