The electrical motion drives are more and more used in various industrial processes. The choice of the motor drive is based on power, speed, precision, and cost requirements. There are many different types of motors for motion drives application. AC and DC motors feature brushed or brushless designs are suitable for a variety of industrial applications. Speed, torque and position control are the most...
The synchronous reluctance motor has gained more attention recently and is a potential candidate to compete with other AC motors. The simple structure and fast torque response make the direct torque control an attractive solution for the synchronous reluctance motor drive system. Different motor, inverter and controller parameters affect the drive system performance in this method. The drive system...
A polar chart of the power converter supply current, comprising phase currents and rotor mechanical position information, is presented, in order to characterize the dynamic operation of a SRM drive. Power converter supply current can be used as additional information of extreme importance when a sensor error or failure occurs. Its analysis is then important and permits to develop appropriate fault...
