Wet high-speed rotating motor with double-toothed stator and rotor

Abstract

The invention provides a wet high-speed rotating motor with a double-toothed stator and rotor. The wet high-speed rotating motor comprises a stator part, a rotor part, a front end cover with an oil inlet, and a rear end cover with an oil outlet, wherein the front end cover and the rear end cover are respectively mounted at the two ends of the stator part in a sealed way, the stator part is arranged at the outer ring of the rotor part, the two ends of the rotor part are respectively connected to the corresponding front and rear end covers in a coupling way, the stator part comprises a flux sleeve and a stator component, the two ends of the stator part are respectively connected with the corresponding front and rear end covers fixedly, and the flux sleeve is arranged at the outer ring of the stator part. The wet high-speed rotating motor has the main beneficial effects that an axial phase split is adopted to ensure simple structure and low cost; the lubricating manner is simple and reliable and is low in cost; the problem that the motor generates a large quantity of heat when the motor rotates at a high speed can be solved and therefore the continuous working time of the motor is prolonged.

Description

Technical field [0001] The invention belongs to an electric-mechanical energy conversion device for variable-speed hydraulic pumps in the field of fluid transmission and control, and in particular relates to a stator-rotor double-open tooth wet-type high-speed rotating electric machine. Background technique [0002] There are two ways to change the flow of a hydraulic pump. One is to change the flow of the pump by changing the displacement of the pump, which is a variable pump in the ordinary sense; the other is to adjust the flow of the pump by directly changing the speed of the pump through a variable frequency motor. , Which is the so-called variable speed pump. Because variable mechanisms are generally more complex and costly, with the development of power electronics technology, variable speed pumps have very bright application prospects in hydraulic engineering. [0003] To achieve large flow for variable speed pumps, high-speed variable frequency motors are the key. Only w...
