BUERSTENLOSER GLEICHSTROMMOTOR. |
摘要 |
A brushless d.c. motor comprises a commutation device by means of which the stator coils are connected to and disconnected from a direct-voltage source in a cyclic switching pattern for energizing said stator coils. In order to reduce torque variations as a result of transient effects in the energizing currents during commutation, the commutation device comprises means which cause the instants of disconnection and connection to be shifted by a fixed time interval relative to one another. |
