Multi-phase electrical machine, e.g. electric linear motor with reduced latching moment, has ratio of number of stimulation poles to number of grooved divisions that fulfill defined relationship

摘要

The electrical machine has a first component that carries main field poles with a groove division on a grooved body (1) and a second component with stimulation poles (5). The ratio of the number of stimulation poles to the number of grooved divisions fulfills a defined relationship. The permanent magnets and the strands can be connected in a star point circuit.
