Abstract

The motor comprises a basal body and a rotor. An external frame of the basal body comprises edge structures along direction of two long axes and two short axes. A stator in use for excitation is accommodated inside the basal body. Including a brake drum with multiple pieces of permanent magnet units installed inside, the rotor sheathed outside the stator is in use for generating torque of magnetic force. An installation part formed in inner side of the brake drum is in use for fixing a positioning frame. The said positioning frame composed of two annular inner and outer pressure plates and peripherals forms multiple accommodation spaces. Permanent magnet units are embedded inside the said accommodation spaces. The positioning frame fixes multiple pieces of permanent magnet units on inner side of the brake drum in order to improve reliability of stuck magnet units and enhance intensity. Four pieces of edge structures can be as installation faces to adapt each conditions of installation.

Description

technical field [0001] The invention relates to a rotor externally rotating permanent magnet motor, in particular to a positioning circular frame that can arrange and fix a plurality of permanent magnets at equal intervals on the inner wall of the brake drum of the rotor to ensure the interval between the permanent magnets Permanent magnet motor with correctness and stability of attachment and positioning. Background technique [0002] The rotational power of the motor is the interaction of the magnetic field generated by the current between the rotor and the stator, and the electrical energy is converted into rotational mechanical energy. Due to the continuous development of new high-permeability permanent magnet materials, the volume and weight of permanent magnets are smaller and the magnetism is stronger. Therefore, the permanent magnet motor made of this high-permeability electromagnet is different from the traditional winding motor Compared with the same torque of the...
