The VYCON Direct Connect (VDC®) system stores kinetic energy in the form of a rotating mass and is designed for high power, short discharge applications. The patented technology within the VDC system includes a high-speed motor generator, active magnetic bearings that are used to levitate and sustain the rotor during operation, and a superior control system that can provide information on the system performance. These innovative technologies enable the VDC to charge and discharge at high rates for countless cycles making conventional technologies like batteries obsolete.

VDC kinetic energy storage systems work like a dynamic battery that stores energy by spinning a mass around an axis. Electrical input spins the flywheel hub up to speed, and a standby charge keeps it spinning 24 x 7 until it is called upon to release the stored energy. The amount of energy available and its duration is proportional to its mass and speed squared. For flywheels, doubling mass doubles energy capacity, but doubling rotational speed, quadruples energy capacity, thus giving VDC a significant competitive advantage.
