Abstract
Effect of rotor geometry on performance of 6/4 switched reluctance motors
Highlights
Switched Reluctance Motors (SRM) have become widely preferred in applications requiring high speed due to their superior characteristics including simple structure, low moment of inertia and high volume/power ratio
Materials and Methods Switched Reluctance Motor (SRM) When a current passes through a phase winding in a switched reluctance motors (SRM), the torque in the motor will cause the rotor to move to the position of maximum inductance, resulting in rotation
This study investigates electrical performance characteristics including shaft speed, phase current, source current, efficiency, electromagnetic torque, and load
Summary
Switched Reluctance Motors (SRM) have become widely preferred in applications requiring high speed due to their superior characteristics including simple structure, low moment of inertia and high volume/power ratio. Their pole rotors do not contain structures such as collector, rings, magnets, brushes, or windings. Other studies have found the ratio of the stator/rotor pole number to be important to the performance of the SRM and have determined that as the ratio, Ns/Nr (Ns/Nr=6/4; 8/6; 12/8; 18/12), is increased, radial forces cause stator vibrations and noise is increased. When high power is required or performance increased, pole width should be increased [12]
