摘要：
The system provides for the commutation of a brushless direct-current motor. A virtual star is provided that is analogous to the motor. The virtual star is formed of resistors. A comparison device continuously comparing the voltages of the two star center points of the motor star and the virtual star in all phases. The comparison results are used to generate a signal for controlling the commutation.
