Problems solved by technology

As far as the current development level is concerned, the main disadvantages of switched reluctance motors are: 1. The torque ripple is relatively large, and the noise problem caused by torque ripple is more prominent; 2. The system reliability is still not high
Although each phase of the current switched reluctance motor can work independently, the reliability and safety are improved compared with ordinary asynchronous motors, but once the phase is missing, the noise will increase sharply, the torque and speed will drop sharply, and even No torque output, resulting in the inability of the entire system to operate

Embodiment Construction

[0020] Depend on figure 1 It can be seen that the present invention includes a controller, a switched reluctance motor and a position detector, the rotor position detector is installed at one end of the motor, and the stator and rotor of the switched reluctance motor include two or more The stator and rotor core.

[0021] figure 2 According to the present invention, it is described as a three-phase 12 / 8 pole motor. The stator core and the rotor of the present invention adopt a multi-pole structure with double salient poles, which are all laminated by ordinary silicon steel sheets. The rotor has neither winding nor permanent magnet, and there is a concentrated winding on the stator. secondary winding. Among them, the stator has 12 magnetic poles, and each phase of the stator contains 2 pairs of radially opposite magnetic poles, and the magnetic poles are arranged in sequence according to the three phases of A, B, and C. The magnetic poles are divided into A1-A4, B1-B4, C1...

Abstract

The invention discloses a switch reluctance motor of distributed multiple driving units. The motor comprises a controller, the switch reluctance motor and a position detector. The motor is characterized in that a stator of the switch reluctance motor comprises two pairs or more than two pairs of reluctance units whose radial directions are opposite; each reluctance unit and the reluctance unit with the opposite radial direction form one driving unit; each driving unit is controlled by different controllers respectively and different battery packs provide power; each reluctance unit is formed by adjacent poles with different phases and a winding. Through adding a pole number of the motor and the number of the driving units, each driving unit can work independently and the plurality of units can work simultaneously so that multi-cylinder driving to an electric car is realized and reliability of a switch reluctance motor speed regulation system is greatly increased. Simultaneously, each driving unit corresponds to the different battery packs so that a bunching effect of the battery is avoided and safety and stability of the battery packs are greatly increased.

Description

technical field [0001] The invention relates to a switched reluctance motor, in particular to a switched reluctance motor including a plurality of distributed multi-drive units. Background technique [0002] With the current shortage of oil resources and the aggravation of environmental pollution, the development of electric vehicles has been paid more and more attention by people. Electric vehicles are characterized by high efficiency and low emissions. Secondly, electric vehicles have fast torque response and fast acceleration, and the motor can be distributed and configured easily to realize four-wheel independent drive and four-wheel steering. It can also realize regenerative braking and energy recovery, improving the safety and reliability of electric vehicle braking. . [0003] At present, there are many drive systems and motors for electric vehicles. The switched reluctance motor speed control system is very important because of its simple structure, high efficiency...
