Performance Enhancement of Wound Rotor Induction Motor by VSI with Dynamic Capacitor Controlled Rotor Circuit
The paper proposes a novel method for improving performance of a Three Phase wound rotor induction motor using an indirect reactive current control scheme in the rotor. A 3 phase VSI with a dynamic capacitor is connected in the rotor circuit for controlling the reactive current in the rotor. The dynamic capacitor is an Hbridge switch with a capacitor in which the duty ratio of the Hbridge circu...
متن کاملPerformance Analysis of Wound Rotor Induction Motor by Dsp Based Rotor Dynamic Capacitor Control
The paper presents a novel secondary reactance control technique in the rotor circuit of a three phase wound rotor induction motor (WRIM). The problem associated with the conventional rotor capacitive reactance control is the demand of exceptionally large capacitance requirement for enhancing the performance of the motor in wide operating range. In the proposed technique, a three phase bridge r...
متن کاملPerformance Improvement of a Slotted Solid Rotor Induction Motor with High Temperature Superconder Coating
This paper analyzes an induction motor with high temperature superconducter (HTS) coated slotted solid rotor. By slotting the solid rotor, the electromagnetic torque near synchronous speed will increase but the starting torque will decrease. To improve starting torque, rotor slots are coated with HTS materials. Using HTS material vary the rotor resistance to great extends in starting step and t...
متن کاملPerformance Comparison Analysis of a Squirrel-cage Rotor Induction Motor with Different Rotor Structures
A new squirrel-cage rotor structure induction motor (IM) that has a auxiliary permanent magnet (PM) rotor and improved cage-rotor structure is presented to enhance the inherent power factor of the IM, and a prototype motor is fabricated by modifying the rotor of a conventional three-phase four-pole squirrel-cage induction motor. The flux linkage, flux distribution, power factor, core loss and e...
متن کاملLosseless Starting Method For The Wound Rotor Induction Motor
In heavy duty drives in the range of hundreds kW, like cement and minerals industries, wound rotor induction motors are used. Important users make use of hundred of such drives, summing hundreds of MW. This type of motors have technical capabilities to easily operate at variable speed. Despite this simple capability, the large amount of losses which occur at low speeds determine the users to us...
