Carbon Fiber Flywheels

Carbon Fiber Flywheels

Beacon’s flywheel is essentially a mechanical battery that stores kinetic energy in a rotating mass. Advanced power electronics and a motor/generator convert that kinetic energy to electric energy, making it instantly available when needed. Our systems are modular and can be configured to meet the power capacity demands of a variety of applications, from 100 kW to multi-MW systems. At the core of Beacon’s flywheel technology is a patented carbon fiber composite rim, supported by a hub and shaft with an attached motor/generator. Together, the rim, hub, shaft and motor/generator form the rotor assembly. Power electronics and the motor/generator efficiently convert electrical energy into mechanical energy when the flywheel is charging and back to electrical energy when discharging. When charging (or absorbing) energy, the flywheel’s motor acts like a load and draws power from the grid to accelerate the rotor to a higher speed. When discharging, the motor is switched into generator mode, and the inertial energy of the rotor drives the generator, creating electricity which is injected back into the grid. Always spinning in the same direction, the flywheel system can instantly shift back and forth between charging and discharging modes. Beacon’s high-performance rotor assembly spins up to 16,000 rpm. The rotor assembly is enclosed in a sealed vacuum chamber which provides a near frictionless environment and also eliminates exposure to oxygen and moisture which extends the life of
