Automatic Phase Advancing in Switched Reluctance Motor by Employing an Electronic Governor for a Desired Speed Angle Profile
Switched reluctance motor (SRM) drive has remarkable characteristics that make it attractive for high-speed applications. As the motor's speed increases the shape of the current waveform changes in such way that limits the production of motoring torque. At high speeds, it is possible for the phase current never reaches the desired value due to the self e.m.f. of the motor, therefore, the torque...
متن کاملSpeed Observer Design for Linear Induction Motor Drives
In this paper, a neural network model reference adaptive system speed observer is designed, which can be used in speed control of linear induction motors (LIMs). Dynamical equations of LIM have been considered accurate. In other words, the end effect and the electrical losses of the motor have been included in the motor equivalent circuit. Then equations of the reference model and adaptive mode...
متن کاملA Study on the Improvement of High Efficiency Blower with 17,000 rpm Speed for Industry Application
The components of blower are composed of motor and impeller. Motors transform electric energy into mechanical rotating kinetic energy and this rotating kinetic energy produces flow through impeller. And thus blower is divided into motor and impeller. In actual development and study, the process of system formation is followed generally by joining the two independent research results. This study...
متن کاملan Efficient Drive Circuit for Switched Reluctance Motor
The purpose of this paper is to present an efficient converter circuit used to drive switched reluctance motors. It uses the C-dump topology in which the trapped energy in the phase windings is returned to the supply capacitor to be used in the following strokes. In addition to the C-dump topology, it uses two extra feedbacks. One comes from a governor mounted on the shaft of motor which contro...
