Comparative Design of Permanent Magnet Synchronous Motors for Low-Power Industrial Applications

Abstract

Permanent magnet synchronous motors (PMSMs) have superior features such as less volume and weight, long-life, high performance compared to induction motors. In this study, a comparative design of PMSMs is provided by considering a 2.2 kW induction motor nameplate parameters which is commonly used in industrial applications. A parametric analysis is used in order to design stator slot and magnet geometries of Surface-Mounted Permanent Magnet Synchronous (SPM) and Interior Permanent Magnet (IPM) Motors to get the high efficiency, low torque ripple. Ansys@Maxwell-2D software using time stepping finite element method is utilized to verify the advantages of designed motors compare to induction motors. In addition, material consumptions of both PMSMs and induction motor are compared to show the effectiveness of proposed motors in mechanically. It is shown that designed SPM and IPM motors have higher efficiency, lower torque ripple and volume than that of induction motors.

The Effects of Magnetic Circuit Geometry and Material Properties on Surface Mounted Permanent Magnet Synchronous Generator Performance

“…The effects of magnet geometry on cost are also among the topics discussed in the literature [13]. The cogging torque is considered comparatively between the axial flux PMSM and the outer rotor PMSM [14] and between the PMSM and the induction motor [15]. Occurring errors during the manufacturing process in the stator slots of the machine, [16] and stator tooth geometries [17] affect the cogging torque.…”

Comparison of Permanent Magnet Electric Motors Used in Electric Vehicles

“…Various IPMSMs have been compared [11]- [14]. In another study, PMSMs were compared with induction motors [15]- [16].…”

Dynamic Investigation of a Permanent Magnet Synchronous Motor for Faulty Operations

“…-Since rotor losses is mainly copper losses causing the heating then PMSM is a good selection since its rotor is free from windings. As a result, PMSM becomes a popular type of electrical machine to be applied in industrial application because of its compactness, efficiency, robustness, reliability, and shape adaptation to working environment [4][5][6]. From another Industrial efficacy of electrical energy is an important feature for our daily life.…”
