Problems solved by technology

Although this motor has greatly improved the electromagnetic braking effect and its power per unit volume, there is a certain torque dead zone during the operation of the single-phase reluctance motor, which increases the vibration and noise of the motor caused by torque ripple.

Also because the starting winding of the rotor needs to be energized, there are corresponding disadvantages due to the addition of brushes.
