Abstract

The utility model discloses a combined permanent magnet self-induction generator motor which is composed of a disc type stator, a radial stator, a permanent magnet rotor, a power switch control system and a power switch control system, wherein the disc type stator generates clockwise torque force on the permanent magnet rotor in the axial magnetic field direction, the radial stator also generates clockwise torque force on the permanent magnet rotor in the radial magnetic field direction, and meanwhile, the disc type stator winding iron core, the radial stator winding iron core and the winding opposite to the permanent magnet rotor are closed by a solid state relay II to be guided to a battery or other electric equipment. Compared with a single disc type or radial type permanent magnet self-induction generator motor, the permanent magnet rotor has larger torque force, the stator winding converts magnetic field energy into electric energy to be output, and the permanent magnet energy is enabled to be utilized more. If the battery is installed on an electric automobile, the cruising ability of the electric automobile is greatly improved, and the consumption of the battery is reduced.

Description

Combined permanent magnet self-induction generator motor Technical Field The utility model belongs to the technical field of permanent magnet motors, and particularly relates to a combined permanent magnet self-induction generator motor. Background In operation of a permanent magnet motor, stator winding current variations produce self-induced electromotive forces (i.e., counter electromotive forces) whose energy is typically dissipated as thermal energy through the winding resistance. The prior art shows that the self-induced electromotive force generated by a permanent magnet motor can recover this energy into electric energy through a power electronic device (such as an inverter) and an energy storage system. For example, when braking, the motor is turned into a generator mode, the current direction is reversely controlled through the inverter, and mechanical energy is converted into electric energy to be stored in a battery or a super capacitor (the application of the permanent magnet synchronous motor in the braking energy recovery of the pure electric commercial vehicle, and an automobile test network). Another patent technology shows that by designing a stator winding without an air gap magnetic circuit, in combination with a full bridge switching circuit, self-induced current can be recovered in real time to a capacitor or battery. For example, when the rotor interacts with the stator magnetic field, the back electromotive force generated by the on-off of the coil is stored through a diode and a capacitor, and high-efficiency energy recovery (CN 1299178A, CN 211239622U) is realized. However, the above-mentioned technologies all involve the realization of electric energy recovery by means of external electric elements or circuit designs, and there are technical problems of complicated structure and complicated electric energy recovery flow. Based on the above, the applicant has developed a permanent magnetic radial self-induction generator motor and a permanent magnetic disk self-induction generator motor respectively, and the self-induction electromotive force generated by the permanent magnetic motor is converted into electric energy by matching with a power switch control system and a power generation control switch which are arranged on the motor by virtue of a unique arrangement structure of a stator and a permanent magnetic rotor and is guided to a rechargeable battery or other electric equipment, so that recycling of the self-induction electromotive force is realized. However, the permanent magnet self-induction generator motor with a single stator has the problems of small torque force of the stator and insufficient utilization rate of magnetic energy of the permanent magnet. Disclosure of utility model The utility model aims to solve the technical problems that the existing permanent magnet motor is complex in electric energy recovery structure and complicated in flow, and the permanent magnet radial type self-induction generating motor and the permanent magnet disc type self-induction generating motor independently researched and developed by the applicant are low in permanent magnet energy conversion and utilization efficiency, and provides a combined permanent magnet self-induction generating motor which realizes the maximum utilization of permanent magnet energy by carrying out electric energy recovery by complementing advantages of a disc type stator and a radial type stator.
