Condition Monitoring and Fault Diagnosis of Induction Motor in Electric Vehicle

Abstract

The twenty-first century is witnessing the growth of electric vehicles due to the declining level of petroleum products and legal concern for clean technology to take care of environmental pollution. Battery and electric motor are the two important components in the electric vehicle. An electric motor is a prime component responsible for the propulsion of a vehicle. Because of the continuous operation and load variation, the motor is subjected to different types of faults. Thus, condition monitoring and on-board diagnosis of an electric motor in the electric vehicle is essential to avoid catastrophic failure. In India, it is observed that the induction motor is commonly used in electric vehicles for propulsion. This article proposes the methodology for condition monitoring and fault identification of components in the induction motor using an on-board diagnostics in an electric vehicle.

Locally optimized chirplet spectrogram for condition monitoring of induction machines in transient regime

“…Induction machines (IMs) are the main mechanical power source of many industrial processes, specially squirrel cage motors [1,2], and are also an important source of power supply networks, specially double fed induction wind generators (DFIGs) [3]. Their failure means an interruption of these power sources, which may lead to sudden stoppage of production lines and may cause high economic losses.…”

A Soft Sensor for Measuring the Wear of an Induction Motor Bearing by the Park’s Vector Components of Current and Voltage

“…The induction motor is the key link and the most susceptible to wear and tear. An analysis of company data [ 10 , 11 , 12 ] identifies a segment of frequently occurring faults and research related to them, of which bearing defects are to be highlighted. Bearing failure leads to deviations in the mating components due to the multi-component nature of electrical machines.…”
