Abstract
Electric drive motor, especially for control and regulation purposes, with a pole and coil arrangement for generating a rotating or linearly advancing armature field, which contains pole-forming segments in a plurality of tracks, staggered over time in their excitation phases and geometrically in the direction of movement. The segments are individual segments or are associated with a plurality of coils (without overlapping). Closely stepped tripping. A preferred embodiment of a synchronous motor, such as a hysteresis motor, is described and represented.
Claims16
An electrical drive motor, for control and regulation purposes, comprising:
- two parallel rows of pole pieces extending in a direction of forward drive, each of said pole pieces having a pole pitch;
- coils positioned straddling both rows of pole pieces for exciting said pole pieces such that pole pieces surrounded by individual ones of said coils are offset relative to each other in the direction of forward drive by a fraction of a pole pitch, said coils being arranged in two layers such that two successively excited coils of different layers are wound around the same pole piece in a pole piece groove and wound around adjacent pole pieces in another pole piece groove.
An electrical drive motor, for control and regulation purposes, comprising two parallel rows of pole pieces extending in a direction of forward drive, each of said pole pieces having a pole pitch;
- coils straddling both of said rows, for exciting said pole pieces, such that pole pieces surrounded by individual ones of said coils are offset relative to one another, in the direction of forward drive, by a fraction of a pole segment pitch, said coils surrounding one pole segment in one row of said two rows of pole pieces and surrounding two adjacent pole segments in another row of said two rows of pole pieces, said coils being arranged in two layers and successively excited coils surrounding a common pole segment in said two rows of pole pieces.
