ABSTRACT:
A brushless dc motor, a method for commutating the motor, and a commutation circuit for the motor are disclosed. The commutation signals which are to be supplied to the motor commutator are stored until released by a control signal. Thereupon, the stored commutation signal is supplied to the commutator and maintained until generation of the next control signal. In the meantime, the next commutation signal is stored awaiting the generation of the next control signal whereupon the next commutation signal will be transferred to the commutator. The brushless dc motor may be operated in a stepping mode and circuit means and a method are disclosed for generating the stepping signal and for operating the motor in the stepping mode.
