BRUSHLESS ELECTRONIC COMMUTED MOTOR

摘要

The invention relates to a brushless, electronically commuted motor, more particularly one used as drive motor for a ventilator drive mechanism in an automobile, comprising a permanent magnetic outer rotor (5), in which a stator (7) with three winding wires staggered at 120~ el is mounted, in addition to several winding coils for each winding wire. The pitch of the coil of the winding coils (15-37) is smaller than the pitch of the pole and 0.5 coils are wound per pole and wire (9, 11, 13). A flat, compact, light-weight, silent and efficient EC motor (1) is obtained due to the fact that each winding wire consists of several parallel-connected windings, the outer rotor (5) has at least p=3 pole pairs and a control plate with conductor rails is provided to connect the individual winding coils.
