Background
At present, most of the traditional asynchronous motors and permanent magnet synchronous motors adopt a magnetic circuit structure of a radial magnetic field, and tile-shaped permanent magnets and rectangular permanent magnets are adopted in the radial magnetic circuit structure. The width of the tile-shaped permanent magnet and the shape and the width of the rectangular permanent magnet pole shoe are adjusted, namely the pole arc coefficient is adjusted. The magnetic flux path of this kind of magnetic circuit structure is: permanent magnet N pole-soft iron pole shoe-magnetic material section-air gap magnetic material section-soft iron pole shoe-permanent magnet S. The permanent magnet in the magnetic circuit structure of the rotor with the radial structure has 4 shapes, and each shape has different application performance differences.
The magnetic field of the permanent magnet disk type motor is axially distributed, the air gap magnetic flux is in the direction of N-air gap-stator-air gap-S pole of the permanent magnet, and when the rotor rotates, alternating potential is induced in the armature winding of the stator. The circular ring type permanent magnet of the disc type structure motor is made to be thinner, and a magnet yoke gasket is required to be matched for use in order to ensure the axial length of a magnetic circuit. Different rotor structures bring differences in performance of the permanent magnet motor and different manufacturing costs, so that the permanent magnet motor has advantages and disadvantages.
The first type of permanent magnet machine has the following disadvantages:
1, because the traditional permanent magnet motor adopts single-circle magnetic steel, the power and the power density are lower.
2, compared with the traditional asynchronous motor, the efficiency of the permanent magnet motor is improved to some extent, but the permanent magnet motor still has iron loss due to the stator core.
3, the stator core also causes hysteresis force when the motor rotates.
4, because of the existence of the stator core, the motor is also heavier, and the material consumption is also more.
5, the coil stator with the iron core structure has large loss, and the heat dissipation performance of the motor is poor.
The conventional permanent magnet disc type motor also has the following disadvantages:
1, the disc type motor also has an iron core, so the motor also has iron loss.
2, because the stator and the rotor are both provided with iron cores, the weight of the motor is heavier, and the material consumption is more.
3, because the traditional permanent magnet disc type motor adopts single-sided magnetic steel, the power and the power density are lower.
4, the existence of the stator core also causes that the motor has viscous force when rotating.
And 5, the disc type motor has larger diameter and larger rotational inertia.
And 6, the coil stator with the iron core structure has large loss and poor internal heat dissipation.
