ABSTRACT:
An easily restarted brushless DC motor has a skeleton type stator core, a rotor core having permanent magnets arranged around it, and needs only one position sensor adapted to detect a rotational position of a rotor and only one stator coil. A controller is provided for switching over the polarity of the electrical power supplied to the stator coil in accordance with an output of the position sensor.
