However, none of the above cooling methods can meet the requirements of high-efficiency cooling. For large-scale motors, the cooling method of cooling liquid through holes in the wires is adopted, but the volume is large and the process is complicated. For motors that require small size, light weight and high-efficiency heat

Abstract

An oil internal circulation cooling motor comprises a coolant oil transfer variable frequency pump assembly 26, a coolant coil heat exchanger 27, a cooling fan 28, an enclosed motor 29 and a coolant oil transfer pipeline 25. The oil internal circulation cooling motor is characterized in that an enclosed motor shell 1 is provided with a coolant oil inlet 4 and a coolant oil outlet 5; a cooling channel 30 is arranged between the outer diameter of a stator 6 and the inner diameter of the shell; two end surfaces of a rotary ball 32 of a rotor 7 are provided with a front end cover plate 14 and a rear end cover plate 15; the front end cover plate 14 and the rear end cover plate 15 form a smooth cylindrical outer surface with the rotary ball 32; and a rotary shaft 13 is provided with a front oil seal 11 and a rear oil seal 36 at inner sides of a front bearing 10 and a rear bearing 9 respectively.

Description

technical field [0001] The invention relates to an oil internal circulation cooling motor. Background technique [0002] At present, the cooling of small motors adopts external air cooling method and internal cooling method, and also adopts the method of interlayer water cooling of the motor shell. However, none of the above cooling methods can meet the requirements of high-efficiency cooling. For large-scale motors, the cooling method of cooling liquid through holes in the wires is used, but the volume is large and the process is complicated. For motors that require small size, light weight and high-efficiency heat dissipation, the above methods cannot There are defects, and how to effectively dissipate the heat of the motor rotor is a problem that cannot be solved by the current technology. Even the heat dissipation problem of the rotor of the wire internally cooled large motor has not solved the effective rotor heat dissipation problem. With the development of science an...
