An asynchronous motor, also known as an induction motor, is a type of electric motor that operates without the need for direct electrical connections between the stator and rotor. Asynchronous motors are widely used due to their simple construction, reliability, and cost-effectiveness. They are prevalent in applications ranging from household appliances to industrial machinery.

The operation of an asynchronous motor involves the creation of a rotating magnetic field in the stator, inducing a current in the rotor. The asynchronous nature arises from the fact that the rotor speed is always slightly lower than the speed of the rotating magnetic field. This speed difference, known as slip, allows the motor to operate efficiently.

Asynchronous motors are known for their ruggedness and ability to handle varying loads. Their straightforward design, coupled with the absence of brushes and commutators, contributes to their low maintenance requirements. These characteristics make asynchronous motors a popular choice in diverse applications where reliability is paramount.
