A switched reluctance motor (SRM) is recognized for its capability for high-speed rotation. Characterized by its simple, cost-effective, and reliable design, an SRM typically features a 4-rotor and 6-slot configuration, operating solely on electromagnetic attraction forces. Unlike traditional motors, SRMs do not require permanent magnets, reducing the dependence on rare earth materials and promoting resource conservation. However, the challenge of mitigating noise and vibration remains, necessitating advancements in semiconductor switching technology.
SRMs are employed in devices demanding high-speed rotational movement, including household appliances like vacuum cleaners and washing machines. Their efficiency, low cost, and reliability also make them potential candidates for electric vehicle propulsion systems.
The SRM's distinctiveness lies in its magnet-free rotor, surrounded by a wire-wound coil within a simple 4-pole, 6-slot structure. The motor operates through the electromagnetic attraction generated when current flows through the coils. Recent advancements in control technology, particularly in power electronics and microcomputers, have improved the operational efficiency of SRMs by enhancing the switching frequency of power control semiconductor devices.
SRMs offer significant benefits, including suitability for high-speed applications and the potential for high output. Their design allows for robust performance in diverse operational contexts.
The primary drawbacks of SRMs involve fluctuations in rotational force at low speeds and the complexity of ensuring rotor position synchronization, which can lead to stepping out of phase.
Step-out, or stalling, occurs when the motor loses synchronization due to overload or rapid acceleration, a challenge that can be mitigated by optimizing motor speed, adjusting current, or employing high-speed motors.
Random tuning, a phenomenon where the rotor experiences misalignment due to conflicting rotational forces, can be addressed by avoiding certain pulse frequencies, utilizing micro-steps, or adding dampers to stabilize operation.
