In this article, a new fault detection technique is proposed for squirrel cage induction motor SCIM based on detection of rotor bar failure. This type of fault detection is commonly carried out, while motor continues to work at a steady-state regime. Recently, several methods have been presented for rotor bar failure detection based on evaluation of the start-up transient current. The proposed ...

This paper presents a new diagnosis method of induction motor faults based on time–frequency classification of the current waveforms. This method is composed of two sequential processes: a feature extraction and a rule decision. In the process of feature extraction, the time–frequency representation (TFR) has been designed for maximizing the separability between classes representing different f...

In this article, a four-phase dual armature-winding wound-field doubly salient machine with distributed field magnetomotive forces (DAW-WFDSM-DF) and corresponding double-redundant rectifier circuit are proposed to improve the electromagnetic performance of traditional WFDSM in terms output voltage ripple, fault-tolerant capability capability. Firstly, due uniformly machine, more feasible stato...

The numerical method, presented in this work, based on the Hilbert transform shows the possibility of improving the dete...

Induction motors are the most common means of converting electrical power to mechanical power in the industry. Induction machines were typically considered robust machines; however, this perception began to change toward the end of the last decade as low-cost motors became available on the market. Nowadays the most widely used induction motor in the industry is a machine which works at the limi...

In this paper a new switching technique for Direct Torque Control (DTC) fault tolerant induction motor drive is presented, if one inverter leg is completely lost due to such abnormal condition, this system modifies the switching table of DTC system using the available stator voltage vectors in two phase mode with Four Switch Three Phase Inverter (FSTPI) topology to track the stator flux referen...

This paper describes online off-site condition monitoring of three phase induction motor by using GSM technology. In this approach, a microcontroller based hardware unit has been developed to continuously monitoring and measure the stator current of the motors. In a motor monitoring system the motor is connected with one microcontroller based hardware unit, which is also connected to Global Sys...

Motors as the actuator in the aluminum electrolysis process, mainly used for control the lifting of the anode to control the cell voltage, make the electrolytic tank keep in the best condition, once the motors failed, slot voltage will be out of control. This paper study on the fault of the motors in the process of aluminum electrolysis. In this paper adopts the EMD algorithm for various stator...
