Abstract
A flywheel energy storage system comprises a rotor having a rotational axis about which the rotor spins in operation and comprising a ferrous material and a housing enclosing the rotor and having an interior subject to a vacuum. The system further comprises a vacuum pump configured to provide the vacuum of the interior of the housing, an electromagnet configured to apply a magnetic field and lift the rotor vertically along the rotational axis of the rotor, and at least one bearing provided between the rotor and the housing, and a controller in operative communication with the electromagnet and the vacuum pump. The rotor applies a force against the at least one bearing.
