noun

1. a type of brushless electric motor in which an alternating supply fed to the windings of the stator creates a magnetic field that induces a current in the windings of the rotor. Rotation of the rotor results from the interaction of the magnetic field created by the rotor current with the field of the stator

Example Sentences

The induction motor provides more power, while the one with permanent magnets is more efficient, Tesla said: Including a rare earth motor boosted the models’ driving range by 10%.

From Reuters

For instance, Tesla was capable of pettiness in intellectual-property disputes — including those he had won, as in the case of the induction motor.

From Nature

Why not go the whole hog and use the output of the transistors to drive what is known as an AC induction motor?

From Economist

An AC induction motor does not need permanent magnets, and can thus do without the expensive rare-earth metals that are an essential ingredient of modern, high-performance magnets.

From Economist

About half a dozen re-boosts would be needed between San Francisco and L.A., but the linear induction motor size needed for re-boosts is much smaller than the initial one.
