Estimation Of parameter For Induction Motor Drive
Generally speed measurement is done with sensor, but disadvantage of sensor is difficult to measure speed at low speeds with sensor. These difficulties are eliminated by using sensor less Flux Orientation Controlled (FOC) . This paper proposes a Model Reference Adaptive System (MRAS) for estimation of rotor speed in FOC. An Induction motor is developed in stationary reference frame and Space Ve...
متن کاملA Novel Equivalent Circuit for Induction Motors under Voltage Fluctuation Conditions
Voltage fluctuation is one of the important types of power quality aspects originated from heavy fluctuating loads. This phenomenon can influence the behavior of induction motors, produce excessive vibration and increase the ohmic losses. In this paper a simplified model to evaluate the electrical characteristics of three phase induction motors under voltage fluctuation conditions will be prese...

Comparison of Induction Machine Equivalent Circuit Models
Most textbooks on electric machines present a classical five-element constant impedance equivalent circuit for modeling polyphase induction machines operating under balanced polyphase sinusoidal steady-state conditions. Yet it is known for cage rotor machines that the rotor element impedances vary significantly with rotor j-equency. Research is in progress to determine a better ac equivalent ci...
