[Abstract]:In order to solve the problem that the air-gap magnetic field of permanent magnet motor is difficult to adjust flexibly, this paper introduces the mechanical magnetic adjustment method into the permanent magnet motor and combines the advantages of built-in permanent magnet synchronous motor. A new type of permanent magnet spin-type mechanical variable flux permanent magnet motor is proposed. This kind of motor is a complex of built-in permanent magnet synchronous motor and mechanical magnetic adjusting device. It will have many advantages such as simple structure, reliable operation, high torque density and good adjusting ability of magnetic field. On the basis of studying the working principle and magnetic adjusting mechanism of the new motor, this paper makes use of the virtual prototype technology to develop the mechanical dynamics simulation, and calculates the steady and transient magnetic field in ANSYS / Maxwell. Analysis of the electromagnetic characteristics of the motor and the ability to adjust the magnetic field. The main research work and results are as follows: (1) the structure and working principle of motor. On the basis of the built-in permanent magnet motor used in the Toyota Prius 2004 electric vehicle, the cylindrical permanent magnet is replaced by the rectangular permanent magnet, and by changing the direction of the permanent magnet, Weakening the main flux of the motor and changing the distribution of the air-gap magnetic field in the motor. (2) the structure and working principle of the mechanical magnetic adjusting device. Two kinds of mechanical magnetic adjusting devices are proposed. One is the mechanical magnetic adjusting device for realizing the self-rotation of the permanent magnet at each pole, the other is the mechanical magnetic adjusting device for the self-rotation of the permanent magnet at the half pole. The working principle of the mechanical magnetic adjusting device is that when the mechanical magnetic adjusting device rotates synchronously with the rotor, the slider in the mechanical magnetic adjusting device will produce centrifugal force and promote the gear self-rotation. There is a transmission link between the gear and the permanent magnet, and the self-rotation of the gear will drive the self-rotation of the permanent magnet. (3) Mechanical design and dynamic simulation. The parameters of each component of the mechanical magnetic adjusting device are designed to make the components of the mechanical magnetic adjusting device realize continuous transmission, and the mechanical dynamics simulation analysis of the mechanical magnetic adjusting device is carried out by using the virtual prototype technology. The spring-shaped variables at different rotational speeds are equal to the self-rotating radians of gears. (4) Mechanical design and dynamic simulation. The parameters of each component of the mechanical magnetic adjusting device are designed to make the components of the mechanical magnetic adjusting device realize continuous transmission, and the mechanical dynamics simulation analysis of the mechanical magnetic adjusting device is carried out by using the virtual prototype technology. The spring-shaped variable at different rotational speeds is equal to the self-rotating radians of the gear. (5) the electromagnetic characteristics of the motor are analyzed. The electromagnetic characteristics such as magnetic field distribution, air gap flux density, winding flux chain, inductive electromotive force, winding self-inductance and mutual inductance are analyzed and calculated. The relationship between the self-rotating angle of permanent magnet and the weak magnetic effect is obtained by direct axis inductance and motor loss. The analysis shows that the internal magnetic field of the motor can be adjusted effectively by the action of the mechanical magnetic adjusting device, and the effect of constant voltage power generation can be achieved, which verifies the rationality of the motor design.
