Single Phase Electric Motor
Single-phase motors are common AC motors. They rely on single-phase electricity to generate a phase difference through components like capacitors, thus forming a rotating magnetic field to drive the rotor to rotate. They are composed of a stator (including the main and auxiliary windings) and a squirrel-cage rotor. They have a low cost and are compatible with single-phase power supplies, but they have a small power output, weak starting torque, and relatively low efficiency and power factor. They are widely used in scenarios such as household appliances, small power tools, and medical devices.
