Wind power yaw brake motor

A wind power yaw brake motor relates to the technical field of motors, is used for solving the technical problem of oil leakage in the use process of the existing wind power yaw speed reducer, and can reduce the maintenance cost of a fan product. In the wind power yaw brake motor, an end cover sealing ring is arranged at the mounting surface position of the front end cover of the full-sealing structure, and meanwhile, a double-framework oil seal is arranged at the position of the main shaft; the junction box is made of ADC12 material castings, and matching surfaces of a junction box cover, a junction box base and a motor base of the junction box are sealed by sealing gaskets made of NR rubber and 1924 sealant in a matched mode, so that the protection grade of the junction box reaches IP65. Moreover, the matching surface of the motor and the yaw speed reducer adopts a full-sealing structure and is subjected to double sealing through a sealing ring and 1924 sealant, and meanwhile, the matching surfaces of all p
