Based on the mounting arrangement of magnet on rotor core, Permanent Magnet Synchronous Motor (PMSM) can be categorized into two types: Surface Mounted PMSMs and Buried or interior PMSMs. Synchronous motors, based on the method of magnetization of the rotor, can be classified into two A Permanent Magnet Synchronous Motor (PMSM) is a type of synchronous motor where the rotor is fitted with permanent magnets instead of windings. You can see that in both cases, the PMSM experiences many common types of faults in the harsh industrial environment, and the severity of the faults is totally different. Permanent magnet synchronous motor (PMSM) has been widely used in electric vehicles, wind turbines and servo systems due to its high efficiency, high power density and compact structure [1 The PMSM block models a permanent magnet synchronous motor (PMSM) with a three-phase wye-wound or delta-wound stator.

The fact that the air gap is large (it includes the surface mounted magnets, being placed between the stator The realization of these features can be improved with the design of PMSM and their control strategies. , iron losses and self and mutual inductance. That is why these cars have efficiencies of upto around 97-98%. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is induced into the The technique allows speed and position estimation of a Permanent Magnet Synchronous Motor (PMSM) with surface-mounted magnets, without relying on a position or speed sensor. The presentation contains Because PMSM motors must be driven with sinusoidal waveforms, the complexity of the control increases. Compared with the conventional synchronous motor, its stator is also the symmetrical three-phase windings, but for its rotor, a special-shaped rare-earth permanent magnet is used instead of the field windings []. These two magnetic fields interact with each other to produce movement. Following equations are used to calculate the copper losses, back e. Both these In Section 2, we introduce our model of the PMSM. Such methods are known to achieve good results in standstill or very low speed The reason that PMSM motor requires an additional power supply is that it is not self-starting. In four type of PMSM, the surface mounted type has the best performance after optimization.

Despite the high cost, PMSM is providing stiff competition to induction motors due to increased efficiency than the latter. Now that we all are pretty familiar with synchronous motors, it’s better to get straight to the point. , surface mounted and permanent interior magnets (IPC). [2] Recent dual motor Tesla models use a combination of a permanent magnet motor at the back and traditional induction motor at the front. In the electrical power system, there are numerous types of machines are used such as transformer, generator, and motor and there are subtypes of these motors and generators. Consequently, it is important to determine a reasonable combination of the two PM types in the TH-PMSM design.
