Multi-magnetic-field loop magnet assembly structure

Abstract

The invention discloses a multi-magnetic-field loop magnet assembly structure. The multi-magnetic-field loop magnet assembly structure comprises a magnetic yoke, magnetic shoes, pole shoes and small magnetic shoes; the magnetic yoke adopts a circular annular shape; the magnetic shoes are uniformly and circumferentially distributed on the inner shell of the magnetic yoke; a first gap is reserved between every adjacent two magnetic shoes; the pole shoes matched with the shapes of the magnetic shoes are paved on the inner surfaces of the corresponding magnetic shoes; a second gap is reserved between every adjacent two pole shoes; the small magnetic shoes are mounted between the second gaps on the two sides of the adjacent pole shoes; the two sides of the adjacent small magnetic shoes and thetwo sides of the pole shoes are spliced and fastened mutually to form external tension to tighten the magnetic shoes on the inner shell of the magnetic yoke; and the magnetic poles of the inner surfaces of the adjacent magnetic shoes are opposite magnetic poles. The multi-magnetic-field loop magnet assembly structure disclosed in the invention is compact in magnetic shoe structure, and the magnetic shoes, the pole shoes and the small magnetic shoes form multiple paths of magnetic circuits, so that the reversing performance is greatly improved, and high magnetic shoe utilization rate is achieved.

Description

technical field [0001] The invention relates to the field of magnet assemblies, in particular to a multi-magnetic field circuit magnet assembly structure. Background technique [0002] A motor is a device that converts electrical energy into mechanical energy. It uses energized coils to generate a rotating magnetic field and acts on the rotor to form a magnetoelectric force rotating torque. Motors are divided into DC motors and AC motors according to the different power sources used. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors. The traditional motor stator is generally composed of magnetic tiles and yokes. The structure is to apply glue to the magnetic tiles and then adhere to the inner shell of the yoke. The other is to add clamping plates between the magnetic tiles to squeeze the magnetic tiles to make them closely match the yoke. The above two structures are single magnetic field circuits, and one magneti...

Problems solved by technology

Since a certain distance must be kept between the magnetic tiles (called the reversing area), if the reversing area is too small, the reversing performance will be poor, and when the reversing area is too large, the utilization rate of the magnetic tiles will be low.
