Abstract

The invention discloses a permanent magnet motor stator and the permanent magnet motor. The stator comprises a stator core and a winding, wherein a plurality of groove structures are arranged on the inner surface of the stator core, the windings are arranged in the groove structures, positioning insertion strips are further arranged at openings of the groove structures, and the positioning insertion strips abut against the windings. The positioning insertion strips are installed in the opening of the groove structure of the stator core, the positioning insertion strips are located on the outerside of the winding and locate the winding so as to prevent the winding from being separated from the opening of the groove structure, and the reliability of the permanent magnet motor is improved.

Description

technical field [0001] The invention relates to a motor, in particular to a stator for a permanent magnet motor and the permanent magnet motor. Background technique [0002] Motors are commonly used electrical components in industrial production. Among them, permanent magnet motors are widely used in industrial production because of their high efficiency and small size. A permanent magnet motor generally includes a stator and a rotor, wherein winding coils are arranged on the stator, and permanent magnets are arranged on the rotor. In the prior art, the stator of the permanent magnet motor adopts a structure in which the stator core cooperates with the winding, and grooves are formed on the stator core to place the winding. However, the coils of the winding are easy to fall off the stator core during actual use, resulting in low reliability in use. How to design a permanent magnet motor with high reliability is the technical problem to be solved by the present invention. ...
