High Power Factor

Permanent magnet synchronous motors (PMSM) can be used directly in place of the induction motors (I.M) for several industrial applications since it is characterized by high efficiency, high power factor, and high power compared to I.M. However, this type of motor suffers from some abnormal conditions that result in minimizing power quality such as voltage sags, temporary disturbances, and faults within the network. In this paper, the behavior of PMSM has been studied under the above conditions in a Matlab/Simulink environment. It was noticed that such problems caused an increase in the amount of torque and current in this motor which impacted negatively on the motor speed and influenced the behavior of PMSM.

Approach Method

This paper suggests the use of the traditional proportional-integral-derivative (PID) controller to control the speed of multi Permanent Magnet Synchronous Motors (PMSMs). The PMSMs are commonly used in industrial applications due to their high steady state torque, high power, high efficiency, low inertia and simple control of their drives compared to the other motors drives. In the present study a mathematical model of three phase four poles PMSM is given and simulated. The closed loop speed control for this type of motors with voltage source inverter and abc to dq blocks are designed. The multi (Master/Slaves approach) method is proposed for PMSMs. Mathwork's Matlab/Simulink software package is selected to implement this model. The simulation results have illustrated that this control method can control the multi PMSMs successfully and give better performance.

Fractional Slot

The calculation accuracy of unbalanced magnetic forces (UMF) is very important to the design of rotor length, because it will effect the shaft deflection. But in some permanent magnet synchronous motors (PMSMs) with fractional slot concentrated windings (FSCW), the UMF caused by asymmetrical stator topology structure is not considered in the existing deflection calculation, which is very fatal for the operational reliability, especially for the PMSMs with the large length-diameter ratio, such as submersible PMSMs. Therefore, the part of UMF in the asymmetrical stator topology structure PMSMs caused by the choice of pole-slot combinations is analysized in this paper, and a more accurate rotor deflection calculation method is also proposed.
