How Does a 12V AC Motor Function?
A 12V AC motor functions by converting alternating current (AC) electrical energy into mechanical energy. The motor consists of three main components: the stator, the rotor, and the windings. The stator contains stationary windings that create a rotating magnetic field when electricity flows through them. The rotor, situated within the stator, is equipped with conductive materials and begins to turn as the rotor experiences the magnetic field’s effects.
The alternating current changes direction periodically, which continually alters the magnetic field in the stator. This process creates motion in the rotor, allowing the motor to produce mechanical work. The speed of the motor depends on the frequency of the AC supply and the number of poles in the stator’s windings. Proper voltage supply is crucial, as a 12V AC motor is designed to operate efficiently at that specific voltage. In summary, a 12V AC motor converts electrical energy into movement through the interaction of its magnetic components.
