Permanent-Magnet Motors for Flywheel Energy Storage Systems The permanent-magnet synchronous motor (PMSM) and the permanent-magnet brushless direct current (BLDC) motor are the two primary types of PM motors used in FESSs. PM motors boast advantages such as high efficiency, power density, compactness, and suitability for high-speed operations.
Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage. For discharging, the motor acts as a generator, braking the rotor to produce electricity.
The speed of the flywheel undergoes the state of charge, increasing during the energy storage stored and decreasing when discharges. A motor or generator (M/G) unit plays a crucial role in facilitating the conversion of energy between mechanical and electrical forms, thereby driving the rotation of the flywheel .
Ekaterina Kurbatova proposed a magnetic system for an axial-type same pole motor suitable as both motor/generator in combination with the integrated design of the motor/generator, which can be utilized in conjunction with the flywheel energy storage system.
