Control system of double-rotor induction motors for hybrid vehicles

Speed-Sensorless Control of Induction Motors for Electric Vehicles

An electric bus system has been operating in the downtown area of Chattanooga, Tennessee for more than four years. The buses use traditional hard-switched IGBT inverters driving special induction motors with a speed sensor (tachometer) and two embedded fluxsensing windings to provide rotor speed and flux information to the motor controller for implementation of high performance field oriented c...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Induction Motors with Rotor Helical Motion

Virtual Instruments for Detecting Rotor Faults in Induction Motors

Rotating electrical machines play an important role in the world’s industrial life. Hence there is a strong demand on their reliable and safe operation. Their faults and failures can lead to excessive downtimes and generate enormous costs in reduced output, emergency maintenance and lost revenues. Therefore the fault detection methods of electrical machines are of real interest. For the rotor f...

Rotor Flux and Speed Observers for Induction Motors

Abstract— The objective of this paper is to investigate the use of observers in the sensorless control of induction motor drives. First, three recently proposed rotor flux and speed observers for induction motors are analyzed and compared using a unified notation. Unresolved issues for each method are noted. Then, an alternative rotor flux and speed observer architecture is described, which is ...
