Find the right devices, application kits and support to control AC Induction Motors with
Infineon's broad range of motor system solutions.
AC Induction motors have the largest share of commercially produced motors. 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, avoiding the need for a direct connection from the power source to the rotating windings.
Key characteristics of an Induction Motor
- Asynchronous – rotor and driving frequency can be different
- Low maintenance, very durable
- No magnets – 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 & efficiency
