Abstract
Abstract An electronically commutated, collectorless direct-current motor is disclosed whose stator has a drum winding and an external magnetic yoke surrounding same, and whose rotor consists of a shaft, a multipolar, permanent-magnet body, and an internal magnetic yoke. To reduce the moment of inertia, the internal magnetic yoke has kidney-shaped apertures. The direct-current motor exhibits a good dynamic behavior and is used in data processing equipment.
