Description

Technical Field

[0001] The utility model belongs to the technical field of permanent magnet motors, and in particular relates to a protective structure for permanent magnet motors. Background Art

[0002] The permanent magnet direct drive motor is mainly composed of various components such as the rotor, end cover, and stator. The stator structure of the permanent magnet direct drive motor is very similar to that of an ordinary motor. The main difference is that its rotor has a unique structure that is different from other motors. High-quality permanent magnet poles are placed on the rotor.

[0003] At present, a rear end cover for protection is fixed to the outside of the rear end shaft of the permanent magnet motor and the cooling fan arranged on the shaft. However, since the rear end cover is hollowed out at the end to facilitate heat dissipation, and there is generally no supporting structure for filling the cavity inside the rear end cover, the motor is prone to deformation when colliding with external objects. Excessive deformation will cause squeezing of the cooling fan within the protection range and limit its normal use. Therefore, a protective structure for the permanent magnet motor is needed to solve the problems existing in the prior art. Utility Model Content

[0004] The purpose of the present utility model is to provide a protective structure for a permanent magnet motor to solve the problems raised in the above background technology.

[0006] It should be noted in the solution that a fixed through-hole is provided on the side surface of the reinforced support shell, and the heat-conducting support column is passed through the fixed through-hole of the reinforced support shell.

[0007] It is further worth mentioning that the reinforced support shell is attached to the inner end wall of the rear end cover, and a communication port is provided on one end surface of the support ring.

[0008] It should be further explained that a heat dissipation hole is provided on one end face of the rear end cover, the support ring is embedded in the heat dissipation hole of the rear end cover, and a connecting port is provided through the support ring and one end face of the reinforced support shell, and the connecting port is connected to the heat dissipation hole of the reinforced support shell.

[0009] As a preferred embodiment, a fixed circular plate is fixed to one end surface of the combined plug plate, a fixed circular plate is provided on the outside of the fixed circular plate, and a dustproof net is fixed between the fixed circular ring and the fixed circular plate.

[0010] As a preferred embodiment, a rotating shaft is provided at the front end of the permanent magnet motor body, and a mounting base is fixed at the bottom of the permanent magnet motor body.

[0011] Compared with the prior art, the protective structure for a permanent magnet motor provided by the present invention has at least the following beneficial effects:

[0012] By setting up a reinforcement structure, the reinforcement support shell, the heat-conducting support column and the support ring can cooperate to support the rear end cover from the inside and achieve structural reinforcement, thereby reducing the trouble of the rear end cover being easily deformed after being impacted due to the hollowing out of the heat dissipation holes and the lack of permanent magnet motor body filling.

[0013] By providing the heat-conducting support column, the heat-conducting support column can conduct the heat inside the rear end cover to the outside, thereby further enhancing the heat dissipation effect without affecting the heat dissipation holes. BRIEF DESCRIPTION OF THE DRAWINGS
