What is the role of the stator and rotor in an induction motor?
Answer : In an induction motor, the **stator** and **rotor** have distinct roles, but they work together to create the motor's operation: ### 1. **Stator**: The stator is the stationary ... field and produces motion in the motor. Together, they convert electrical energy into mechanical energy (motion)....

What is a stator motor?
Answer : A stator motor is a type of electric motor where the **stator** (the stationary part of the motor) generates a magnetic field that interacts with the **rotor** (the rotating part). The rotor ... , and this motion can be used to power machines or appliances like fans, pumps, and electric vehicles....
