Abstract

The invention discloses a motor outer rotor magnetic pole protection layer forming method. In the method, a glue injection requirement and automatic separation of a thermal expansion non-metal block and a magnetic pole protection layer after glue injection are achieved through thermal expansion and cold contraction of the thermal expansion non-metal block, auxiliary glue injection components suchas a vacuum bag film, demolding cloth and a flow guide net do not need to be used, a preparation procedure before glue injection is simplified, a workload is greatly reduced, and a glue injection period can be shortened. And by using the forming method, through controlling pressure between the thermal expansion non-metal block and an internal portion of an annular component, the magnetic pole protection layer is tighter, a solid heat transfer speed is high, the high-quality magnetic pole protection layer can be formed only through one-time glue injection, and a production period is further shortened. Furthermore, the thermal expansion non-metal block is naturally separated from the magnetic pole protection layer after the glue injection is completed, there is almost no residual resin on the surface of the thermal expansion non-metal block, dangerous wastes are greatly reduced, and an environment is protected while cost is reduced.

Description

technical field [0001] The invention relates to the technical field of motor rotor magnetic pole protection, in particular to a forming method of a motor outer rotor magnetic pole protection layer. Background technique [0002] Permanent magnet motor is an electromagnetic device that converts mechanical energy and electrical energy through the medium of magnetic field. It is widely used in various power generation places. Among them, the magnetism of the permanent magnet material of the permanent magnet motor is one of the important factors affecting the power generation performance of the permanent magnet motor. [0003] The permanent magnet motor includes rotor body, bead, magnetic pole parts, etc. The rotor body is generally cylindrical. The pre-processed bead is installed on the inner peripheral wall of the rotor with fasteners such as bolts. Axially push to the corresponding position between the adjacent bead, the cross-section of the bead is generally trapezoidal, tha...
