Abstract

This ring motor stator, which comprises the following parts: magnetic yoke part with arc shape and its protruding part along radium direction and several gear parts to form plug tank between with certain distance to form several cutting stator iron chip; stator coil outside magnetic yoke; several insulation iron chip of the magnetic yoke parts and gear parts and stator iron chip; protruding part set relative to the binding place near to the insulation; one integration part to integrate insulation parts and stator iron chips.

Description

technical field [0001] The invention relates to a stator of an annular electric machine. Background technique [0002] As shown in Fig. 1 and Fig. 2, the stator of the ring-shaped motor in the prior art includes the following parts: a split stator core 111 that is combined with each other to form a ring-shaped semicircular shape; The stator coil 115 of the core 111; the insulating member 121 which houses the divided stator core 111 inside and insulates the divided stator core 111 and the stator coil 115 from each other. [0003] Each of the divided stator cores 111 is provided with: a semicircular yoke portion 112a; the inner side of the above-mentioned yoke portion 112a protrudes along the radial direction, and is arranged at intervals along the peripheral direction, so that an insertion hole is formed therebetween. A plurality of gear tooth portions 112b of the groove. [0004] On both ends of each of the above-mentioned yoke parts 112a, there are respectively formed wel...
