Abstract
An internal induction coil is used to heat the rotor of an ECM. This provides a localized heating and dilation of the bore of the rotor prior to the heating of the outer surface of the rotor. The crankshaft is located in the heated bore and acts as a heat sink. As a result, the outer surface of the rotor is not heated such as might cause the loss of magnetic properties.
