Embodiment Construction

[0070] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0071] The mathematical model of the switched reluctance motor is established on the Ansoft Maxwell software of the present invention, and the mathematical model of the external circuit is also established at the same time, and the coupling between the external circuit and the finite element is completed. By simulating the switched reluctance motor, the performance curve can be obtained; then the finite element analysis is carried out on the two-dimensional static magnetic field and the three-dimensional transient magnetic field, and then the static magnetic field distribution diagram of the switched reluctance motor under d...

Abstract

The invention belongs to the technical field of electromagnetic induction, discloses a finite element analysis method of a switched reluctance motor and an external circuit thereof, determines parameters of the motor, performs electromagnetic design, and obtains a 2D / 3D model. The magnetic density profiles of the rotor with static field and 40A voltage at 0 degree, 7.5 degrees, 15 degrees and 22.5degrees were compared. The torque and rotational speed waveform is obtained by adding external circuit into the transient field. By analyzing the waveform and comparing the angular magnetic density distribution under different conditions, the external circuit design method of switched reluctance motor is as follows: through the reasonable design of some parameters of electronic components relatedto the external circuit, and then connect these electronic components to form the external circuit. The invention obtains relevant data in Ansoft Maxwell through finite element analysis and externalcircuit design of the switched reluctance motor, carries out data analysis and comparison, further optimizes and improves the design, and enables the motor to become more efficient and energy-saving.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic induction, and in particular relates to a finite element analysis method of a switched reluctance motor and an external circuit thereof. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] The switched reluctance motor is a new type of speed-regulating motor. The speed-regulating system has the advantages of both DC and AC speed-regulating systems. Compared with other types of motors, this kind of motor is excellent. In terms of cost, the materials used in the motor are relatively cheap, the structure is also very simple, and the speed and efficiency are much higher than other types of motors. The cost of motors currently on the market is higher than this motor. The four main components of the switched reluctance motor are the controller, power converter, motor and position detector. [0004] Nowadays, switched relu...
