Abstract

The invention relates to magnetic poles of synchronous motors, in particular to a synchronous motor magnetic pole with a waterproof function. The problem that an existing synchronous motor magnetic pole is poor in waterproof performance is solved. The synchronous motor magnetic pole is of a magnetic pole waterproof structure for a synchronous motor, and the magnetic pole waterproof structure is characterized in that after a pole core is completed, a coil is directly manufactured on the pole core in a winding mode, epoxy glue is used for spraying and sealing, baking and solidification are carried out, the pole core and the coil are integrated, and the requirement for water prevention is met. The structure can completely meet the design requirement for the synchronous motor magnetic pole structure.

Description

technical field [0001] The invention relates to a magnetic pole of a synchronous motor, in particular to a magnetic pole of a synchronous motor with waterproof function. Background technique [0002] In recent years, as synchronous motors are used more and more in harsh working environments, there are more and more situations where the motor is insulated from the ground, low in resistance or even burned due to factors such as water ingress and moisture in the motor. Therefore, the internal structure of the motor should be improved. Waterproof performance is an inevitable choice to ensure the long-term safe operation of the motor and reduce losses. [0003] The magnetic pole structure of the existing synchronous motor such as figure 1 , 2 As shown, its structural characteristics are as follows: [0004] (1) The magnetic pole core (magnetic pole body) and the magnetic pole coil wire are processed and manufactured separately. [0005] (2) The magnetic pole coil adopts a cop...
