Induction motors are gear motor the most common kind of motor used in commercial production. It can be viewed as an AC transformer with a rotating secondary winding. The current in the rotor windings is induced from the current in the stator windings, gear motor avoiding the need for a direct connection from the power gear motor source to the rotating windings.
Key Characteristics Induction Motor
- Asynchronous: rotor and driving frequency can be different
- Low maintenance, high durability
- Magnet-free: coil windings make up the rotor and stator
- No brushes needed: current from supply to the stator coils induces a field on the rotor cage or coils
- No controller necessary for single speed and predictable load operation
- Fit with Variable Frequency Drives (VFD) for improved control and efficiency
