Single-stage motors have a stator. They do not have the rotating magnetic field attributes of polyphase or polyphase motors. The magnetic field created by the stator windings is pulsating, not rotating. When the rotor is stationary, the expansion and contraction of the stator’s magnetic area create an electrical recent in the rotor. The existing makes the rotor magnetic field with the opposite polarity to the stator magnetic discipline. The reverse polarity applies rotational force to the upper and reduce components of the rotor. Because this power passes by way of the heart of the rotor, it remains equal in each and every direction, maintaining the rotor stationary. If the rotor commences to switch, it continues to switch in the route it began, due to the fact the rotor’s momentum results in a rotational power in that direction. Single-stage motors are employed in reduced-electricity apps this sort of as ceiling fans, mixer grinders, and home appliances this sort of as portable electrical power instruments.
