Embodiment 1

[0022] see Figure 1-5 . The invention is an axial magnetic field permanent magnet motor, which includes a stator and a rotor.

[0023] The rotor is composed of a rotor yoke 1 and a permanent magnet 2, and in the rotor, the permanent magnet is fixed on the rotor yoke. In this embodiment, there are four permanent magnets, the surface magnetic poles are N-S-N-S in sequence, and they are made of N35 grade NdFeB, and the rotor yoke is made of magnetically conductive steel.

[0024] The stator is composed of a tooth body 5 made of amorphous alloy strip, a coil 4, a tooth top 3 and a stator yoke 6 made of soft magnetic composite material. In the stator, there are slots under the tooth top 3, and the same number of slots as the tooth body 5 above the stator yoke 6, and the two ends of the tooth body are respectively inserted into the slots of the tooth top and the stator yoke. The coil 4 is wound in the slot formed by the adjacent teeth. In this embodiment, there are 12 tooth bod...

Abstract

The invention provides an axial magnetic field permanent magnetism motor, comprising a rotor and a stator, wherein the rotor is composed of a rotor yoke and a permanent magnet; the stator is composed of a gear body and a coil which are manufactured by amorphous alloy strips, and a gear top and a stator yoke which are manufactured by soft-magnetic composite materials. The scheme of preparing a permanent magnetism motor by amorphous alloy and soft-magnetic composite materials, and a corresponding manufacturing method can utilize advantages of two materials, and meanwhile avoid disadvantages of the two materials in machining.

Description

technical field [0001] The invention relates to a permanent magnet motor, in particular to an axial magnetic field permanent magnet motor in which an amorphous alloy and a soft magnetic composite material are simultaneously used in a stator core, and a manufacturing method thereof is disclosed, which belongs to the field of motors. Background technique [0002] Today, with the increasing shortage of traditional energy, environmental pollution, greenhouse effect and other issues are becoming more and more serious, how to improve the efficiency of energy conversion has become the most concerned topic in the entire industry. As the motor with the largest power consumption in industrial processes, further improving its efficiency and power density has become a top priority for relevant practitioners. Traditional motors mostly use electrical silicon steel sheets to manufacture the stator core of the motor. However, in the occasions with high speed or frequency, such as direct dr...
