The existing high-temperature brushless DC motor drive device usually consists of a motor body, a fixed base, and a fixed shell.

[0003] For example: The utility model with application number CN202121669791.9 discloses a side-by-side DC motor drive device, which specifically includes a main housing, a linkage housing matched with the main housing, and a brushless motor device arranged in the main housing, wherein the main housing is provided with a motor cavity for accommodating two brushless motor devices, and the linkage housing is provided with a driving spindle and a linkage device, and when the linkage housing is matched with the main housing, the output ends of the two brushless motor devices are inserted into the linkage housing and the driving spindles are driven to rotate through the linkage device.

[0012] Beneficial Effects

[0013] The utility model discloses that when inspecting and repairing the driving device, the staff first pulls the auxiliary plug rod to make the auxiliary plug rod away from the locking block, and then pulls the connecting slide rod to make the connecting slide rod drive the guide slide seat to move, and then through a series of transmissions, the connecting column is disengaged from the first limit plate.
