Abstract
A rotor for use in an electrical motor which includes an anti-expansion ring centrally mounted on the rotor to restrict the extent rotor elements mounted on a rotatable shaft may expand outward due to centrifugal forces generated when the motor is operated. Such motors are suited for use in high rotational speed environments such as electrically controlled turbochargers.
