AC induction motors are common power tools in a wide range of applications. Their operation relies on the interaction between a rotating magnetic field and conductive conductors within the motor's rotor. This interaction induces currents in the rotor, producing a magnetic field that interacts with the stator's field. The resulting forces result in the rotation of the rotor, converting electrical energy into mechanical energy.
The frequency of the rotating magnetic field is directly connected to the frequency of the read more AC supply voltage. Increased frequencies result in more rapid rotor speeds. Induction motors are renowned for their reliability, simplicity, and low maintenance requirements, making them a popular choice in industrial and domestic applications alike.
