Problems solved by technology

At present, the more common dual-rotor motors on the market are mostly TORUS-type, which is composed of a stator and two rotors; but the same dual-rotor motor also has many problems, because it has multiple excitation sources inside, and its magnetic field is chaotic and easy to cause interference. The working efficiency of the motor has been reduced and needs to be improved

Embodiment Construction

[0023] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer ” refer to directions towards or away from the geometric center of a particular part, respectively.

[0024] As shown in the figure, a new motor rotor structure described in the present invention is applied to a double-rotor motor. By changing the structure, the traditional copper wire turns are replaced by permanent magnets. The inner side of the outer rotor core and the outer side of the inner rotor are arranged with The permanent magnets are arranged separately in sequence. ...

Abstract

The invention discloses a novel motor rotor structure. The structure is applied to a double-rotor motor. Permanent magnets are arranged at the inner side of an external iron core; the permanent magnets are sequentially and separately arranged; in order to reduce magnetic interference between adjacent magnetic poles, a trapezoidal hole is formed in an iron core above each magnetic pole; similarly,a trapezoidal hole is formed in the corresponding position corresponding to an inner rotor, grooves are formed between the trapezoidal holes and the corresponding magnetic poles, and magnetizers are placed in the grooves. Besides, during the arrangement of the magnetic poles, magnetism isolating sheets are inserted into gaps among the magnetic poles, thereby reducing the mutual interference again,and improving the power density and the working efficiency of the permanent magnet motor.

Description

technical field [0001] The invention belongs to the field of motors, and in particular relates to a novel motor rotor structure. Background technique [0002] An ordinary permanent magnet motor mainly includes a stator and a rotor. The rotor includes a rotor iron core and permanent magnets. The permanent magnets are installed in the magnetic steel groove of the rotor iron core; the stator includes an iron core and an energized armature. [0003] In order to improve the efficiency of the motor, the double excitation source motor came into being, which is the later double rotor motor. At present, the more common dual-rotor motors on the market are mostly TORUS-type, which is composed of a stator and two rotors; but the same dual-rotor motor also has many problems, because it has multiple excitation sources inside, and its magnetic field is chaotic and easy to cause interference. The working efficiency of the motor is reduced and needs to be improved. Contents of the inventi...
