The area of multiphase variable-speed motor drives in general and multiphase induction Motor drives in particular have experienced a substantial growth since the beginning of this century. Research has been conducted worldwide and numerous interesting developments have been reported in the literature. An attempt is made to provide a detailed overview of the current state-ofthe-art in this area....
Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...
The objective of the paper is to develop a microcontroller controlled four switch three phase inverter (FSTPI) to drive three phase induction motor with minimum hardware. This inverter uses four switches instead of conventional six switches, it has lesser switching losses, lower electromagnetic interference (EMI), less complexity of control algorithms, robust control and reduced circuit complex...
The multiphase induction motor is considered to be the promising alternative conventional three-phase motor, especially in safety-critical applications because of its inherent fault-tolerant feature. Therefore, attention many researchers has been paid develop different techniques for detecting various fault types motors, securely switch control mode drive system post-fault operation mode. sever...
Recent research reveals that multi-phase motors in electric propulsion systems are highly recommended due to their improved reliability and efficiency over traditional three phase motors. This presented a comparison of optimal model design six squirrel cage induction motor (IM) for by using Genetic Algorithm (GA) Particle Swarm Optimization (PSO). A is designed simulated ANSYS Motor-CAD. In ord...
Induction motor is the most popular load in the industry, it is very important to study about the effects of voltage quality on induction motor performance. One of the most important voltage quality problems in power system is voltage unbalance. This paper evaluates and compares two methods including finite element method (FEM) and equivalent electrical circuit simulation for investigation ...
Due to low cost, evaporative coolers are used in most of the central regions and in the warm and dry climate of Iran and are considered as one of the major consumers of electrical power. Most evaporative coolers use single-phase induction motors by connecting directly to the power grid. But their eefficiency is very low, and their replacement with high efficiency electric motors is considered b...
Induction Motor especially the squirrel cage type of this motor plays important role in industry. According to the application type, this motor place against various stresses that are caused failure in the motor. The most common failure is related to the Stator winding. Among these failures are turn-to-turn, coil-to-coil and phase to phase faults. Flow the high current do to the induction resul...
