Abstract

The application provides a glass sintered brushless DC motor end cover, comprising: an end cover body (2), including an inner end face and an outer end face along the direction of closing the motor, the center of the end cover body (2) has a penetrating inner The central through hole on the end face and the outer end face is used to install the bearing (1), and the end cover body (2) also has a strip-shaped through hole (6) penetrating through the inner end face and the outer end face, which is used to install the terminal (3) The terminal (3) is an electrical conductor, and its two ends have blind holes (10) extending to the center respectively, which are respectively used to connect with the wires inside and outside the end cap; the glass body (4) is used to sinter the wiring The column (3) is fixed in the strip-shaped through hole (6). The sealing end cover of the aviation DC brushless motor of the present application effectively simplifies the structure of the motor, reduces the length and volume of the motor, reduces the weight of the motor, improves the manufacturability and reliability of the motor, and ensures the weight index of the aircraft. Strict requirements.

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...
