Description

Technical Field

[0001] The utility model relates to the technical field of magnetic shoes, in particular to a novel magnetic shoe for a DC permanent magnet motor. Background Art

[0002] Magnetic tiles are a type of permanent magnet that is mainly used in permanent magnet motors. They are a type of strong magnetic material and are mainly used in permanent magnet DC motors. Unlike electromagnetic motors that generate magnetic potential sources through excitation coils, permanent magnet motors use permanent magnetic materials to generate constant magnetic potential sources. Permanent magnetic tiles have many advantages in replacing electric excitation, which can make the motor structure simple, easy to maintain, light in weight, small in size, reliable in use, with less copper, low copper consumption, and low energy consumption. Magnetic tiles can be used to manufacture electromagnetic devices such as motors, generators, electromagnetic locks, and sensors. The strong magnetism of magnetic tiles makes these devices run more efficiently and stably. For example, the authorization announcement number is CN10. A magnetic tile disclosed in 4319920A includes a magnetic tile body, characterized in that the magnetic tile body has a fan-shaped cross-section, an arc-shaped outer side surface, and a flat inner side surface, and the outer sides of both ends of the magnetic tile body are provided with a stepped mounting portion for facilitating the sleeve connection of a rotor cap, and the magnetic tile body is provided with a plurality of protrusions on the left side and a plurality of grooves on the right side, the protrusions and grooves corresponding to each other. The above-mentioned magnetic tile is installed on the rotor through the grooves and the stepped mounting portion. Due to the lack of a structure for fixing the magnetic tile, the vibration effect generated when the motor rotates may cause the magnetic tile to loosen, thereby changing the distance between the magnetic tile and the rotor, thereby affecting the performance of the motor.
