Abstract

The invention provides a glass-sintered brushless direct-current motor end cover, which comprises an end cover body (2) which comprises an inner end face and an outer end face in the direction of a canned motor, wherein the center of the end cover body (2) is provided with a central through hole running through the inner end face and the outer end face and used for installing a bearing (1), and the end cover body (2) is further provided with a strip-shaped through hole (6) running through the inner end face and the outer end face and used for installing a binding post (3); the binding post (3), which is an electric conductor, and the two ends of which are provided with blind holes (10) extending towards the center and used for being connected with wires inside and outside the end cover; and a glass body (4), which is used for fixing the binding post (3) in the strip-shaped through hole (6) in a sintering manner. According to the aviation direct-current brushless motor seal end cover, the structure of the motor is effectively simplified, the length and the size of the motor are reduced, the weight of the motor is reduced, the manufacturability and the reliability of the motor are improved, and the harsh requirements of an airplane for weight indexes are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of air motor seal design, in particular to a glass sintered brushless DC motor end cover. Background technique [0002] At present, the aviation brushless DC motor includes two parts: the motor and the controller. When the motor drives the oil pump, the heat dissipation method can be cooled by oil. The motor is designed with an aviation fuel flow channel. The oil pump pressure is used to make a part of the fuel flow inside the motor, which can take away the heat of the motor and realize the efficient heat dissipation of the motor. The motor transmits the Hall signal and the winding power supply is generally connected by a sealed socket and a plug to realize power transmission and sealing. This method is bulky and has low reliability. Contents of the invention [0003] In order to solve at least one of the above technical problems, the present application provides a glass-sintered brushless DC motor end co...
