What are the application characteristics and scope of application of permanent magnet direct drive motors?

For the normal use of permanent magnet direct drive motors, have you ever wondered why this product can gain such a large market share in the market? In fact, this product is very beneficial to everyone. Only by ensuring that the product has the advantage of use can it occupy a favorable position in such fierce market competition. Permanent magnet direct drive motor products well meet this feature. Therefore, many manufacturers also hope to obtain some economic benefits from it. For ordinary people, we naturally need to know some relevant knowledge, so that we will not be deceived by some unscrupulous merchants in future procurement.

Compared with other types of motors, permanent magnet direct drive motors have higher power, mass ratio and smaller size, so they will play a greater advantage in the use process. In addition, for the motor, its speed and braking performance are also very good. This use characteristic is also one of the main reasons why permanent magnet direct drive motors have attracted much attention in the market. However, if the material vibrates during normal use, the permeability may be reduced under the action of high temperature and overload current. In this case, only demagnetization can occur, which may reduce the performance of the permanent magnet direct drive motor.

The application of permanent magnet synchronous motor in the field of industry and agriculture is gradually widespread, and it can be said that it has been very widely welcomed. In today's society, new technologies are constantly emerging. If you want to gain a firm foothold in the market, you must constantly adjust your products to have better development prospects. The excitation mode of permanent magnet synchronous motor has been continuously developed and improved. After continuous adjustment, the products are gradually applied to more fields. As for the application of permanent magnet synchronous motor, it is also very extensive. A mass production machine needs to run continuously at a constant speed in one direction. In addition, permanent magnet synchronous motors have the advantages of low cost, simple and reliable structure, and convenient maintenance, and are very suitable for driving motors.

The basic principle and structure of the direct drive motor is permanent magnet, and a special disc motor is designed. At the same time, the space between the two end faces of the outer rotor structure is fully utilized to fix the stators of the two disc motors and the stators of the outer rotor structure together. The rotor discs of the two disc motors and the rotor cylinder of the outer rotor structure form a three-dimensional closed outer rotor. Under the same space volume, this composite structure can produce a larger electromagnetic torque than the single outer rotor structure and the single disc structure. Direct drive linear motors are mainly used in levitation conveyor systems. The motor meets the following conditions in the system: flat structure and limited volume. One-way operation, frequent starting, running time is seconds; starting current should be less than the starting current of the same capacity motor, with small impact and fast response; simple structure, low cost and light weight.

The direct drive hybrid three-dimensional permanent magnet direct drive motor is composed of three relatively independent stator and rotor groups, which can be regarded as a cylindrical outer rotor permanent magnet direct drive motor and two disc axial flux permanent magnet direct drive motor. But these three are not completely independent, but the unity of mutual influence and interaction. In order to make the direct drive compound three-dimensional permanent magnet direct drive motor rotate and output torque, three electromagnetic systems consisting of three stator and rotor groups need to be coordinated.
