Classification and material characteristics of permanent magnet motors

The editor has previously introduced the insulation treatment of explosion-proof permanent magnet motors in detail. It can be seen that insulating the equipment can improve the corresponding performance. So what are the classifications of permanent magnet motors? And what are its material characteristics? Next, I will introduce it to you in detail!

Classification:

Permanent magnet motors do not only refer to the permanent magnet synchronous motors we often call, but broadly refer to motors containing permanent magnets. This type of motor does not require excitation and can be roughly divided into: permanent magnet DC motor (with commutator), without Brushed DC motor (DC motor characteristics, electronic commutation), permanent magnet synchronous motor (AC motor characteristics, also the type produced by our company), etc.

The permanent magnet synchronous motor is just a classification of the permanent magnet motor, and the components of the permanent magnet synchronous motor include the following: stator, magnet rotor, position sensor, electronic reversing switch, etc.

Permanent magnet synchronous motors have the characteristics of simple structure, small size, light weight, low loss, high efficiency, and high power factor. They are mainly used for the update of high-performance servo transmission systems and DC motors that require fast response, wide speed range, and accurate positioning. Replace the motor.

Material features:

The internal materials and product characteristics of permanent magnet motors are very important evaluation requirements and inspection structures for some professionals. What kind of operating methods and structural characteristics of synchronous motors can be called a synchronous motor? This is a truly good motor. Through today’s analysis, I will have a deeper understanding of it.

The main materials used in permanent magnet materials are the positive waves composed of the axis Rao Zu magnetic field and the hysteresis loss proton rotation of some motor eddy currents, as well as some assumed injective stator voltage equations established in the data model, and sometimes the control of the motor. It is due to some of its vector control and direct torque control. Regarding the characteristics of its vector-controlled permanent magnet motor, it is mainly based on the control of the electromagnetic chain and the control of the rotating shaft and current to weaken the field, making it possible to control the permanent magnet motor. The amount of output current increases.

For permanent magnet motors with direct rotor control, it is an opposite method to control the displacement. It mainly uses the orientation of the stator magnetic link to use two discrete points to control the magnetic link and the rotation axis of the motor. Obtain the adjustment range used to change the current and voltage.
