Motor Current Signature Analysis of a Variable Speed Drive for Motor Fault Diagnosis

The induction motor is one of the most used electric machines in the industry because of its strong and simplicity. This paper investigates the performance of conventional techniques such as sideband analysis in detecting broken rotor bars when the motor is fed from a common pulse width modulation voltage source inverter PWM‐VSI drive for variable speed drives. The phase current signals are obt...

Improved Direct Torque Control of Induction Motor Drive under Low Speed Operation

This paper presents a modified two level inverter topology to improve the low speed performance of the direct torque controlled (DTC) three phase induction motor drive. Proposed method is based on current ripple principle. In this technique, the inverter switching states are derived as a function of rotor speed. This method gives low ripple in flux and torque at low speed operation when compare...

A Novel MRAS Based Estimator for Speed-Sensorless Induction Motor Drive

In this paper, a novel stator current based Model Reference Adaptive System (MRAS) estimator for speed estimation in the speed-sensorless vector controlled induction motor drives is presented. In the proposed MRAS estimator, measured stator current of the induction motor is considered as a reference model. The estimated stator current is produced in an adjustable model to compare with the measu...
