Description

technical field [0001] The invention relates to the technical field of motors, in particular to a vertical semi-direct drive permanent magnet synchronous motor. Background technique [0002] Most of the existing mills, mixers and other equipment that require vertical power input use the "asynchronous motor + coupling + multi-stage vertical gear device" drive device, which has complex structure, high manufacturing cost, low efficiency, and insufficient reliability. bulge problem. [0003] The problem of oil leakage in the existing vertical gear device occurs from time to time. The planetary gear device of the vertical semi-direct drive permanent magnet synchronous motor adopts oil pool lubrication, which has the risk of oil leakage. The lubricating oil will corrode the stator winding, reduce the insulation of the winding, and easily lead to faults such as winding leakage, short circuit, and even fire; if the lubricating oil leaks from the output shaft end, it will pollute th...

Problems solved by technology

[0002] Existing mills, mixers and other equipment that require vertical power input mostly use "asynchronous motor + coupling + multi-stage vertical gear device" drive device, which has complex structure, high manufacturing cost, low efficiency, and insufficient reliability. Prominent problem

[0003] The oil leakage problem of the existing vertical gear device occurs from time to time. The planetary gear device of the vertical semi-direct drive permanent magnet synchronous motor is lubricated by an oil pool, and there is a risk of oil leakage. If the planetary gear device leaks oil, the lubricating oil enters the inside of the motor, The lubricating oil will corrode the stator windings, reduce the insulation of the windings, easily cause winding leakage, short circuit and other failures, and even cause fires; if the lubricating oil leaks from the output shaft end, it will pollute the work site and affect production. In order to solve the above problems, this The invention provides a new type of vertical combined sealing structure, which can effectively improve the sealing performance of the vertical semi-direct drive permanent magnet synchronous motor and reduce the risk of oil leakage
