Abstract:

Aim: The purpose of this work is to investigate how permanent magnet motors can increase an electrical vehicle's efficiency as compared to an SRM by minimizing power loss. Materials and Methods: By minimizing power loss, the permanent magnet motor and SRM are used to increase efficiency. Permanent magnet motors are thought of in group 1 whereas SRMs are thought of in group 2. There are a total of 40 sample sizes, with 20 samples in each group. The computation for G power is 0.8. Results: From the data, it can be seen that there was a statistically significant difference between the two groups of 0.045 (p 0.05). Both the novel SRM and the permanent magnet motor classifier have achieved efficiency values of 66.35% and 70%, respectively. The efficiency of a permanent magnet motor is between 50% and 70%, whereas that of an SRM is between 50% and 70%. SRM has lower switching loss than permanent magnet motors at the same switching frequency. Conclusion: From this work the efficiency of the SRM is best compared to the permanent magnet motor.

I. Introduction

The electric motor is responsible for enabling the creation of motion from electricity. They are a varied class of machines that offer power for an incredible number of applications and now control manufacturing, automation, commercial items, and other areas [7]. Because there are so many different kinds of electric motors available, these motors are incredibly versatile [5]. The one potential form of electric motor: the permanent magnet motor. Although being created at a young age, this motor is now fast replacing industry norms as a viable option because of modern technological improvements. This talk will examine this motor, its operating concepts, and its applications, illuminating why it has attracted so much interest recently [10]. In terms of design, permanent magnet motors are a modern motor that are comparable to both induction motors and servo motors. They are made up of a rotor, which is the moving component attached to the motor's output shaft, and a stator, which is the outer casing [13]. The permanent magnet motor, like other AC motors, uses permanent magnets (often rare earth magnets) placed in its rotor to harness the energy efficiency of the mechanics of electromagnetic force to create torque by the electrical vehicles [11]. This design differs from the majority of conventional electric motors, where the rotor is either made entirely of a ferromagnetic metal or creates its own magnetic field by induction, the use of a DC power source, or another method. A permanent magnet motor is referred to as a synchronous motor because, with the magnets appropriately positioned in respect to the stator, it can produce speeds equal to the excitation current frequency. These machines have only lately found their footing as a workable design as the energy efficiency since their motors need to be combined with an electrical component that reduces their torque [1]. In vehicles, permanent magnet motors are typically used to power blowers that raise and lower windows, run windscreen washers and wipers and operate heating and air conditioner blowers. These electrical vehicles including the motors are also utilized in portable electric tools including drilling machines and hedge trimmers, as well as computer drives, the toy industry, electric toothbrushes, portable vacuum cleaners, and food mixers [9].
