Oil magnetic-suspension double-stator high-efficiency motor

Abstract

The invention discloses an oil magnetic-suspension double-stator high-efficiency motor, belonging to the technical field of clean energy and energy-saving motors. A first stator and a second stator are arranged on the inner side and the outer side of a rotor; a center and a main shaft are fixed together; and the main shaft supports the rotator to rotate through a second bearing and a third bearing. The oil magnetic-suspension double-stator high-efficiency motor is characterized in that a raised part on the front end of the shell of the rotor penetrates through the end covers of the stators and is used as a transmitting outputting shaft, and the inner wall and the outer wall of the shell of the rotor are provided with permanent magnets. The heat in the motor is discharged along with liquid through a lifting pump, and the heat is returned to the interior of the motor to circulate after flowing through a cooler to be cooled. The weight of the rotor is overcome due to the adoption of the oil magnetic-suspension cooling technology, the bearings have no friction loss and noise, the motor works constantly in the ideal controllable temperature increasing state, the maximization and the stability of the output power are ensured. The oil magnetic-suspension double-stator high-efficiency motor can be used together with an electric vehicle, a giant wind power generator, a large-scale hydroelectric generator, a diesel generators, a large-scale high-speed smelting fan and other equipment as an energy-saving motor or a high-efficiency power generator, thereby having a huge economic benefit and energy saving and environment protecting effects.

Description

technical field [0001] The invention relates to a high-efficiency oil-floating double-stator motor, which belongs to the technical field of clean energy and energy-saving motors, and particularly relates to an energy-saving motor suitable for electric vehicles, giant wind generators, hydroelectric generators, internal combustion engine generators, etc. High efficiency generator equipment. Background technique [0002] In the prior art, a motor or a permanent magnet motor consists of a stator and a rotor. When manufacturing a higher-power motor, the volume of the stator and the rotor must be increased in proportion, so there are common problems of large volume, low efficiency, and high cost. The disadvantages, especially there is no cooling and heat dissipation device in the motor, the temperature rise of the motor that rises with the load increases is easy to make the permanent magnet aging, limit the output power of the motor, and curb the development of high-power motors. ...

Problems solved by technology

[0002] In the prior art, a motor or a permanent magnet motor consists of a stator and a rotor. When manufacturing a higher-power motor, the volume of the stator and the rotor must be increased in proportion, so there are common problems of large volume, low efficiency, and high cost. In particular, there is no cooling and heat dissipation device in the motor. The temperature rise of the motor that rises with the load increases will easily cause the permanent magnet to age, limit the output power of the motor, and curb the development of high-power motors.
