Abstract
A new rotor start-up system is provided for application to rotating systems such as stationary or vehicular electromechanical battery systems. An embodiment of the system consists of a “locator” that includes a stationary permanent-magnet pole above which is a circular ferromagnetic (e.g., iron) strip embedded in the lower, inner edge of the flywheel rotor. The lower edge of this strip is wave-like so that the magnet can pull the rotor around to a position where the position relative to the minimum capacity between the rotor and stator electrodes is such as to launch the rotor in a chosen direction, i.e., either clock-wise or counter-clockwise. Startup from rest is then accomplished by applying a short high-voltage ac or dc pulse to the EMB capacitor.
