Power supply for providing instantaneous energy during electric utility outage

A power supply system for providing instantaneous power to a load during a power failure of a utility normally providing utility power to the load in the absence of the power failure, the system comprising,

• a flywheel rotated at a high speed to provide kinetic energy,
• a synchronous machine rotating at a low speed,
• magnetic coupling means for magnetically coupling the flywheel to the synchronous machine, the magnetic coupling means comprises induction bars coupled to and rotating with the flywheel and comprises field coils coupled to and rotating with the synchronous machine,
• sensor means for detecting the power failure,
• disconnecting means for disconnecting the utility power form the load, and
• control means for controlling the magnetic coupling means to control an amount of the kinetic energy transferred energy from the flywheel to the synchronous machine providing instantaneous power to the load, the control means controls the amount of the kinetic energy transferred from the flywheel to the synchronous machine by controlling the amount magnetic coupling between the induction bars and the field coils.

A power supply assembly controlled by a control unit for connecting instantaneous power to a load during a power failure of a utility normally providing utility power to the load in the absence of the power failure, the assembly comprising,

• a tubular flywheel rotated at a high speed to provide kinetic energy,
• a magnetic clutch comprising induction bars rigidly attached to the flywheel and field coils the field coils and induction bars are magnetically coupled over a gap extending between the field coils and the induction bars,
• a split core transformer comprising primary windings and secondary windings coupled to the field coils for controlling the amount of magnetic coupling between the induction bars and the field coils, the secondary windings and field coils are rigidly attached to the shaft and rotate with the shaft,
• a synchronous machine connected to the utility and coupled to the shaft when the synchronous machine functions as a motor for driving the shaft to rotate the synchronous machine at a low speed, the synchronous machine is disconnected from the utility when the providing the instantaneous power to the load during the utility failure,
• a drive motor for rotating the flywheel at the high speed,
• a clutch control means for providing a variable voltage control signal to the primary windings during the utility failure for generating magnetic flux into the field coils for controlling the amount of magnetic coupling between the flywheel and the synchronous machine,
• a frame for supporting the synchronous machine in coupled alignment with the shaft,
• a housing supported by frame and for encapsulating the flywheel and comprising two apertures through which extends the shaft and between which are disposed, in order along the shaft, the primary windings, secondary windings, the field coils, the induction bars, the flywheel, and the drive motor, a first set of ball bearing means disposed the between shaft and the housing for rotating the shaft, the secondary windings and the field coils relative to the housing at the low speed, and
• a second set of ball bearings disposed between the flywheel and the shaft for rotating the flywheel at the high speed relative to the housing.
