VARIABLE SPEED ELECTRO-MECHANICAL DRIVE

摘要

An electrical machine and method for driving at least one ancillary device of a motor is provided wherein the electrical machine comprises a stator, configured to be rotated, and a rotor, rotatably mounted relative to the stator, coupled to the ancillary device. The speed of the rotor may be a function of the rotational speed of the stator and the frequency of a supply current supplied to the electrical machine and thus drives the ancillary device at a demanded load/speed.

1. An electrical machine for driving one or more ancillary devices of a motor, the electrical machine comprising:
a stator configured to be rotated; and a rotor rotatably mounted relative to the stator, and wherein a rotational speed of the rotor of the electrical machine depends upon a supply current to the electrical machine and a rotational speed of the stator.
