Speed sensorless vector control of 3-phase induction motor under open-phase fault (faulty 3phase induction motor) based on Indirect Rotor Field-Oriented Control (IRFOC) is proposed in this paper. To ensure high performance FOC of induction motor drives, the estimation of the rotor speed is necessary. However, the algorithm used to estimate the rotor speed for a 3-phase induction motor cannot be...

For low power wind energy or micro-hydel applications of the order of 1-10KW, the lowest cost can be achieved if the generator is a simple squirrel cage induction motor used as a self excited induction generator (SEIG). The induction generator output can be rectified to produce a DC Bus from which a single phase inverter can feed the power supply grid. A SEIG requires capacitors to be connected...

For machine drive applications, multiphase induction motor could potentially meet the demand for high power electric drive systems which are both rugged and energy efficient. High phase number drives possess several advantages over conventional three phase drives such as high torque, higher reliability and increased power. Multiphase induction motors have found many applications such as electri...
