3 phase squirrel cage induction motors are an affordable and efficient type of motor commonly used in industrial applications. They are low maintenance and have excellent heat regulation, ensuring a reliable and low cost motor. They are available with various pole configurations and are commonly used in applications such as:

Blowers and fans
Machine tools
Conveyor belts


How is the speed determined?

3 phase induction motors feature two main components that can influence the speed of the motor, these include a rotor and a stator. Once a current is applied across the stator, a rotating magnetic field is created inducing a current in the rotor. As a result, the rotor also creates a magnetic field and begins to follow the stator. In addition, the number of poles in the windings of a motor can greatly determine the motors speed. If a motor has a higher number of poles it will tend to have a slower rated speed but a higher rated torque.
