What Is The Permanent Magnet Synchronous Motor?
The Permanent Magnet Synchronous Motor (PMSM) is a type of electric motor that operates using permanent magnets embedded in its rotor. It is also sometimes referred to as a brushless AC motor or a synchronous permanent magnet motor.
In a PMSM, the stator (the stationary part of the motor) contains a series of coils that are energized in a sequence to create a rotating magnetic field. The rotor (the rotating part of the motor) contains a series of permanent magnets that are arranged to produce a magnetic field that interacts with the magnetic field produced by the stator.
As the two magnetic fields interact, the rotor rotates, producing mechanical energy that can be used to power machinery or other devices. Because the permanent magnets in the rotor provide a strong, constant magnetic field, PMSMs are highly efficient and require less energy to operate than other types of electric motors.
PMSMs are used in a wide variety of applications, including electric vehicles, industrial machinery, and household appliances. They are known for their high efficiency, low maintenance requirements, and precise control, which makes them a popular choice for many different types of systems.
Analysis of the principle of the technical advantages of permanent magnet motor:
The principle of a permanent magnet synchronous motor is as follows: In the motor's stator winding into the three-phase current, after the pass-in current, it will form a rotating magnetic field for the motor's stator winding. Because the rotor is installed with the permanent magnet, the permanent magnet's magnetic pole is fixed, according to the principle of magnetic poles of the same phase attracting different repulsion, the rotating magnetic field generated in the stator will drive the rotor to rotate, The rotation speed of the rotor is equal to the speed of the rotating pole produced in the stator.
The development trend of rare earth permanent magnet motors:
Rare earth permanent magnet motors are developing towards high power (low speed, high torque), high functionality, and miniaturization, and are constantly expanding new motor varieties and application fields, and the application prospects are very optimistic. In order to meet the needs, the design and manufacturing process of rare earth permanent magnet motors still need to be continuously innovated, the electromagnetic structure will be more complex, the calculation structure will be more accurate, and the manufacturing process will be more advanced and applicable.
Application of rare earth permanent magnet motor:
Due to the superiority of rare earth permanent magnet motors, their applications are becoming more and more extensive. The main application areas are as follows:
Focus on the high efficiency and energy saving of rare earth permanent magnet motors. The main application objects are large power consumers, such as rare earth permanent magnet synchronous motors for textile and chemical fiber industries, rare earth permanent magnet synchronous motors for various mining and transportation machinery used in oil fields and coal mines, and rare earth permanent magnet synchronous motors for driving various pumps and fans.
Depending on how magnets are attached to the rotor and the design of the rotor, permanent magnet synchronous motors can be classified into two types:
Surface permanent magnet synchronous motor (SPMSM)
Interior permanent magnet synchronous motor (IPMSM).
SPMSM mounts all magnet pieces on the surface, and IPMSM places magnets inside the rotor.
The SPMSM, or non-salient pole synchronous motor, features a rotor with a surface-mounted permanent magnet and a symmetrical magnetic circuit in both the quadrature and direct axes. On the other hand, the IPMSM, or salient pole synchronous motor, has a rotor with a permanent magnet embedded in the iron core. It possesses an asymmetric rotor magnetic circuit that generates additional reluctance electromagnetic torque, resulting in a high power density. Moreover, it offers a wide field weakening range, making it suitable for high-speed motor operations.
The SPMSM and IPMSM differ in terms of rotor structures and magnetic circuits, leading to varied performances. Compared to the SPMSM, the IPMSM exhibits higher efficiency, greater cogging electromagnetic torque ripples, and lower losses at high temperatures. However, the IPMSM also experiences higher-frequency harmonics, which can cause eddy current losses in both the stator and the rotor.
When designed to operate with a fixed frequency power source, all the mentioned types of synchronous motors are equipped with a damper winding, similar to the squirrel-cage winding of an induction motor. This damper winding is utilized for starting the machine as an induction motor and also serves the purpose of reducing hunting oscillations that can occur during transient operations. However, when the motor is supplied with a variable frequency source capable of seamless frequency variation from zero to the rated value, the damper winding is not necessary for starting. Its requirement may arise in certain cases to dampen hunting oscillations or serve other specific purposes.
