| 318161000 | WITH FLYWHEEL OR MASSIVE ROTARY MEMBER | 6 |
| 20090200968 | Drive Apparatus and Method for Its Operation - A drive apparatus with at least one synchronous motor, a converter and a mechanical energy buffer able to be fed from an energy supply network, which, for converting mechanical energy into electrical current, includes a first asynchronous machine, and a method of operation for such a drive apparatus are specified, with which or in which the energy buffer, especially its first asynchronous machine is directly electrically connected via a switchover device to the at least one synchronous motor, so that the converter included in the drive apparatus is bypassed for such a switch position of the switchover device and the converter accordingly does not have to be designed for currents which flow in such a switch position of the switchover device. | 08-13-2009 |
| 20110074318 | DUAL DRIVE ELECTRIC REGENERATOR - The dual drive electric regenerator (DDER), an electric power regenerative device in which a heavy driven-backend flywheel combination being coupled directly to the drive shafts of a specially designed electric generator with dual drives. The driven flywheel with magnetic Pole pieces attached to its circumference area being rotated by the magnetic forces imparted from a driver flywheel with magnetic Pole pieces attached to its circumference surface and rotated by an electric driver motor with its speed being controlled electronically. The DDER expends less input power than the output power generated by the flywheel combination and converted to electrical power by the said generator. The initial power to start the motor being derived from an internal battery. A part of the output power generated being used as the input power through recharging the battery continually and the rotational process being sustained by completing a power regenerative cycle. | 03-31-2011 |
| 20110234125 | ARRANGEMENT FOR SUPPLYING POWER TO A COUPLED SYSTEM OF MACHINES - An arrangement for supplying power to a system includes a first electric drive unit constructed to supply mechanical power to or receive mechanical power from a first coupled system of machines and a second electric drive unit constructed to supply mechanical power to or receive mechanical power from a second coupled system of machines. The first and second coupled system of machines are constructed to receive mechanical power or mechanical energy or to supply mechanical power or mechanical energy. The arrangement further includes a first kinetic energy storage device having a first electrical energy exchange machine which is electrically connected to the first electric drive unit, and a second kinetic energy storage device having a second electrical energy exchange machine which is electrically connected to the second electric drive unit. The first kinetic energy storage device is coupled to the second kinetic energy storage device. | 09-29-2011 |
| 20120062154 | Flywheel System Using Wire-Wound Rotor - A flywheel is described having a rotor constructed of wire wound onto a central form. The wire is prestressed, thus mitigating stresses that occur during operation. In another aspect, the flywheel incorporates a low-loss motor using electrically non-conducting permanent magnets. | 03-15-2012 |
| 20130175953 | Sequential pulse firing of multiple motors in an flywheel array - A method of initiating sequential pulse firing of a motor to reduce energy consumption in machines that have both rotational and linear kinetic energy stored in them by pulsing the motor at variable frequency without reducing total kinetic energy in the machine below a predetermined level. | 07-11-2013 |
| 20160079826 | ENERGY STORAGE MANAGEMENT SYSTEM - An illustrative energy storage system includes an energy storage device, a processor coupled to the energy storage device, and a memory coupled to the processor. The memory is configured to store instructions adapted for execution by the processor to control and monitor operation of the energy storage device. The instructions are arranged into functional modules. Each functional module is associated with a memory cache in the memory. Control processes depending on the functional module read last known values from the associated memory cache. Reading last known values from the associated memory enables changes to the functional modules without shutting down the energy storage device. | 03-17-2016 |
