A novel control algorithm for the charge and discharge modes of operation of a flywheel energy storage system for space applications is presented. The motor control portion of the algorithm uses sensorless field oriented control with position and speed estimates determined from a signal injection technique at low speeds and a back electromotive force(More)
A flywheel energy storage device stores energy in a rotating mass. These devices can be used to perform the same function as traditional chemical batteries. In terms of the energy storage function, a flywheel system has significant advantages over chemical batteries: length of life, energy density, power density, and the capability of deep depth of(More)
