High-Speed Permanent Magnet Motor Generator

The VDC systems’ motor generator design utilizes specialized rare earth magnets to minimize rotor heating and maximize efficiency and reliability. This type of motor design allows the system to cycle quickly without overheating and can, therefore, be used in difficult applications with high cycling and long life requirements. The motor generator is rotated at speeds up to 36,750 RPM, where the flywheel system is at a fully charged state. During discharge, the rotor speed decreases to a minimum speed, typically 10,000-12,000 RPM. This speed range is called the discharge range and can be adjusted for more energy or higher cycling depending on the application. The rotor assembly of the flywheel operates in a vacuum provided by an external pump. By removing air from the rotating area of the motor, all windage losses from the system are eliminated, increasing electrical efficiency. https://vyconenergy.com/technology/
