Description

Technical Field

[0001] The utility model relates to the technical field of assembly workbenches, in particular to an assembly workbench for a permanent magnet synchronous motor. Background Art

[0002] Permanent magnet synchronous motors use permanent magnets to provide excitation, which makes the motor structure simpler, reduces processing and assembly costs, and eliminates slip rings and brushes that are prone to problems, thereby improving the reliability of motor operation. Because no excitation current is required and there is no excitation loss, the efficiency and power density of the motor are improved.

This makes the assembly of the permanent magnet synchronous motor time-consuming and labor-intensive and affects the assembly efficiency. Therefore, an assembly workbench for a permanent magnet synchronous motor is proposed to solve the above-mentioned problems. Utility Model Content
