Abstract

The invention discloses a combined efficient motor with switched reluctance motors and double disk type permanent magnet motors with axial magnetic fields. The combined efficient motor comprises is characterized in that a left rotor disk, a middle stator and a right rotor disk form the double disk type permanent magnet motors with the axial magnetic fields, the left rotor disk, the right rotor disk, a left SRM (switched reluctance motor) stator and a right SRM stator form the two switched reluctance motors, and the left SRM stator and the right SRM stator are arranged on end covers. The stator is shared by the double disk type permanent magnet motors with the axial magnetic fields; and each disk type permanent magnet motor and the corresponding switched reluctance motor share the corresponding rotor disk, tooth sockets on circumferences of the rotor disks are ventilating slots of the disk type permanent magnet motors to realize cooling effects, and are also used as rotor teeth of the switched reluctance motors, and the tooth sockets and the SRM stators form the switched reluctance motors. Accordingly, the combined efficient motor with the two switched reluctance motors and the double disk type permanent magnet motors with the axial magnetic fields has a ventilating cooling structure, space is sufficiently utilized, two types of motors are smartly combined with one another, and the combined motor is high in efficiency.

Description

technical field [0001] The invention belongs to a high-efficiency motor combined with a double-disk axial magnetic field permanent magnet motor and two switched reluctance motors. More specifically, it involves an axial field permanent magnet motor composed of a middle stator and two rotor disks, and the two rotor disks are also used as the rotor of a radial field switched reluctance motor, and has a self-ventilating cooling structure. The invention makes full use of the inner space, cleverly combines two kinds of motors, integrates 4 motors, and has the characteristics of compact structure, high power density and high efficiency. Background technique [0002] Permanent magnet motors are widely used in various fields and people's daily life. According to the direction of the magnetic field, permanent magnet motors can be divided into two types: radial magnetic field and axial magnetic field. Axial field motors are also called disc permanent magnet motors. At present, the s...

Problems solved by technology

At present, the single-disk axial field permanent magnet motor is widely used, which has high working efficiency, but the power range is small, and the speed and torque output are single. The cooling method is mostly air-cooled or fan-cooled outside the motor. The water-cooled type with a water jacket inside the motor has a more complicated structure.
