Abstract

Through self-buckling slot for stator, punch pieces of stator are stacked to form stator body. Neck groove of stator are prepared on inner side face of stator faced to rotor. Number of the neck groove is equal to number of permanent magnet taken in by rotor. Multiple stator windings are inserted in neck groove. Characters are that boltholes are setup on stator in direction parallel to line of rotation axis. Through the boltholes, one end face of stator is fixed on stator seat of engine assembly directly. The invention realizes high output efficiency, and high output power, easy to produce generator with larger power, as well as stability, durability, and reliability. Features are: no chassis, simple structure, compact, thin, light weight, and miniaturization.

Description

technical field [0001] The invention relates to a stator of a multi-pole inner rotor type permanent magnet generator, in particular to a generator suitable for miniaturization, light weight and thinning, and belongs to the technical field of generators. Background technique [0002] Before the disclosure of the present invention, in the known technology, the stator of the permanent magnet generator was also disclosed. For example, a motor generator disclosed in PCT / US2004 / 015485 includes a motor generator with a plurality of permanent magnet elements. The rotor, these permanent magnets are arranged in a circular ring structure around the axis of rotation, the magnet elements are continuously alternating in magnetic polarity along the surface of the inner ring, and the stator is separated from the rotor by a radial air gap, and the stator includes a plurality of magnetic core segments , the core segments have respective coils wound thereon to form stator windings, each stator...
