Title: ELECTRIC MOTOR
Abstract:
An electric motor (5) has a motor housing, which has peripheral cooling ribs (15) for dissipating heat originating in the motor. The cooling ribs (15) extend only over a part of the periphery of the motor housing (5), such that there is room in the part of the motor housing (5) without cooling ribs for cooling ribs (21) of the electronics housing (13), which are arranged aligned with the cooling ribs (15) of the motor transversely to the motor axis (14).
