A multi-working mode dual-stator magnetic field modulation motor

Abstract

The invention discloses a multi-working mode dual-stator magnetic field modulation motor, which comprises an inner stator, a rotor, an outer stator, a permanent magnet, a first set of windings, a second set of windings; a first layer of air gaps and a second layer of air gaps They are respectively arranged between the inner stator and the rotor, and between the outer stator and the rotor; several stator teeth are arranged on the circumference of the stator, and the ends of the stator teeth have one or more small slots to form modulating teeth. The tooth end is composed of permanent magnets and modulating poles; the rotor is composed of magnetic conductors and non-magnetic conductors arranged alternately; the inner stator slot is embedded with a centralized first set of windings, and the outer stator slot is embedded with a centralized second set of windings; The purpose of the two sets of windings is determined according to the specific working mode. The multi-working mode dual-stator magnetic field modulation motor of the present invention can be applied in the field of transportation to solve the problem that the working performance of the motor cannot meet the actual needs under multiple working conditions due to complex and changeable road conditions.

Description

technical field [0001] The invention belongs to the technical field of novel motor manufacturing, and in particular relates to a dual-stator magnetic field modulation motor with multiple working modes, which is suitable for electric drive systems with complex working conditions such as electric vehicles and ship drives. Background technique [0002] With the continuous development of industrial technology, permanent magnet motors are widely used as power devices in electric vehicles, ship drives and other fields due to their advantages such as high power density and high torque density. However, in this type of transportation field, due to the complexity of the external road conditions, the demand for motors is often complex and changeable. On the climbing road with high resistance or the sea level with strong wind, the motor needs to have a large output torque, and in some occasions, it is hoped to have a fast movement speed and quickly reach the designated position. There...

Problems solved by technology

However, in actual working conditions, although hybrid excitation permanent magnet motors are widely used in low-to-medium speed and high-speed applications due to their variable magnetic field characteristics, compared with permanent magnet motors in low-speed and high-torque applications, hybrid excitation motors Often cannot meet the requirements of high torque density and power factor

Therefore, although permanent magnet motors and hybrid excitation motors can exert their own unique advantages in their specific operating areas, motors with a single working mode cannot meet the needs of the entire operating area
