specific Embodiment approach

[0022] A specific embodiment of the present invention is as follows:

[0023] During the acceleration process of the electric vehicle / electric vehicle, a large torque is required. At this time, the series switches 11, 12, and 13 of the motor are in the normally closed and on state, and the two sets of parallel switches 21, 22, 23 and 31, 32, 33 are in the off state. state, the first group of coil windings A1, B1, C1 are connected in series with the second group of coil windings A2, B2, C2, such as figure 1 As shown, the motor can provide the maximum torque at this time.

[0024] When the electric vehicle / electric vehicle accelerates to the first speed setting value, the torque needs to be reduced. At this time, the series switches 11, 12, and 13 are disconnected from the on state according to the instructions of the control system, and the first group of parallel switches 21, 22, and 23 are connected at the same time, at this time, the first group of coil windings A1, B1, and...

Abstract

The invention discloses a multi-winding motor for an electric vehicle / electric automobile, and belongs to permanent magnet direct current motors. The multi-winding motor comprises a rotor and a stator, wherein the rotor rotates around the shaft of the rotor; the stator encircles the rotor; the stator is provided with more than one coil winding which is divide into first coil windings (A1, B1 and C1) and second coil windings (A2, B2 and C2); the first and second coil windings are mutually independent and can be connected in series and in parallel through a relay selector switch according to a requirement. The motor can serve as an alternating current motor to generate power.

Description

technical field [0001] The invention relates to a multi-winding motor for electric vehicles / electric vehicles, which belongs to permanent magnet DC motors and is used in the field of electric vehicles / electric vehicles. The electric motor can act as an alternator to generate electricity. Background technique [0002] Existing electric motors include a rotor surrounded by a stator. The stator includes coil windings. After electrification, a magnetic field is generated, which interacts with the magnetic field of the permanent magnet rotor to generate torque, causing the rotor to rotate. A single coil winding cannot produce the same output efficiency at both low and high speed rotation. Contents of the invention [0003] The invention provides a multi-winding motor for electric vehicles / electric vehicles, which belongs to permanent magnet DC motors and is used in the field of electric vehicles / electric vehicles. Multiple coil windings can be operated in series and in para...
