Problems solved by technology

[0002] When a conventional motor starts, the slip between the rotor and the air-gap magnetic field is relatively large, and the speed at which the air-gap magnetic field cuts the rotor conductor is relatively high, so the starting current is relatively large, which may easily lead to impacts on the power grid and peripheral equipment

Abstract

The invention relates to the technical field of motors, in particular to a double-rotor motor, and the motor comprises a first rotor and a second rotor which are sleeved together; the first rotor comprises a plurality of working windings, the plurality of working windings surround the axis of the second rotor, the first rotor is provided with a first transmission shaft, and the second rotor is provided with a second transmission shaft; the torque superposition device comprises a machine base, a first transmission wheel connected with a first transmission shaft, a second transmission wheel connected with a second transmission shaft and a third transmission wheel rotationally connected with the machine base, the first transmission wheel and the first transmission shaft coaxially rotate, and the second transmission wheel and the second transmission shaft coaxially rotate; the first transmission wheel and the second transmission wheel are in transmission connection with the third transmission wheel, and the rotation direction of the first transmission wheel is opposite to the rotation direction of the second transmission wheel. The starting current is smaller, and the impact on an external network and peripheral equipment during starting is smaller.

Description

technical field [0001] The invention relates to the technical field of electric motors, in particular to a double-rotor electric motor. Background technique [0002] When the conventional motor is started, the slip between the rotor and the air-gap magnetic field is relatively large, and the speed at which the air-gap magnetic field cuts the rotor conductor is relatively high, so the starting current is relatively large, which may easily cause shocks to the power grid and peripheral equipment. Contents of the invention [0003] Aiming at the problems of the prior art, the invention provides a double-rotor motor with small starting current. [0004] The present invention adopts the following technical solutions: a dual-rotor motor, a fixed part, a torque superposition device and a dual-rotor structure, the dual-rotor structure includes two rotors nested together, one of which is called the first rotor, and the other One rotor is called the second rotor, the first rotor inc...
