Abstract

Many authors have recently studied line start permanent magnet assistance synchronous reluctance. This paper presents a method to improve the electromagnetic torque and efficiency of induction motors of 7.5kW-4P (which consists of 36 stator slots and 40 rotor bars) by changing the design of the permanent magnet assistance synchronous reluctance rotors. This means that permanent magnets will be inserted to the squirrel cage induction motors (induction motors). The electromagnetic torque and efficiency of an induction motor is analyzed and compared with that of the line-start synchronous reluctance motor via a finite element analysis. In addition, the influence of position and length permanent magnets on the electromagnetic torque and efficiency of the line-start synchronous reluctance motor is also considered and simulated. The model of this motor Linh is finally designed with four U layered- magnet rotor to verify the developed method. The development of the method is also validated on the practical induction motor.
