Abstract
Super premium efficiency (IE4) line-start permanent magnet synchronous motor (LSPMSM) is one of the good alternatives to the squirrel cage induction motor (SCIM), especially for a line-start application. Motor performance parameters like efficiency, input power consumption, power factor, starting behavior and torque ripple are affected primarily because of the customary power quality indices. The problems originate due to furnaces, power electronic converters, nonlinear loads, digital controllers, modern electrical equipments and lively load variations. Hence, the performance analysis of LSPMSM and SCIM is essential to understand the motor behavior. Voltage harmonic distortion, voltage unbalance factor and long-duration voltage variation are considered in this study. Customary power quality indices (CPQI) are collected using power and energy analyzer in a sugar industry at various measured points. In the present study, 2.2 kW LSPMSM is designed and prototyped for constant load operation. The designed motor and SCIM are used for analyzing the performance using finite element analysis under the influence of measured CPQI and the effects on its individual performance parameters.
