    摘要: An electrically commutated, collectorless direct-current motor is disclosed whose stator has a self-supporting drum winding and a cylindrical plastic body which is located concentrically with the drum winding in a winding head. The cylindrical plastic body has recesses which contain eyehooks. The ends of the drum winding are connected with the eyehooks, which are welded to a circuit board. The invention makes it possible to automate the connection of the winding ends to the circuit board.

    摘要: A control circuit bipolarly controls the stator of a 4-phase brushless DC motor in which the staor windings are connected in a ring circuit with only four semiconductor switches. Also, two control sequences are possible: a first control sequence consisting of four switching events per revolution and number of pole pairs, in which only two semiconductor switches are activated at a time, and a second control sequence consisting of eight switching events per revolution and number of pole pairs, in which alternately two and three semiconductor switches are activated simultaneously.

    摘要: 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.

    摘要: An electronically commutated, collectorless direct current motor having a permanent magnet rotor comprised of a cup-shaped hollow cylinder in whose interior an internal magnetic yoke is arranged, an internal stator core and an external stator core. A stator drum winding comprises a plurality of phase windings wound on an insulating body with a portion of the stator winding being commingled with the phase windings in a plurality of slots of a slotted stator. The insulating body has a novel shape for arranging the stator winding thereon and for inserting the insulating body into a plurality of slots of the external stator core.
