An electric vacuum pump is used in the flywheel energy storage system to create a partial vacuum inside the flywheel cavity. A closed oil circuit cooling system maintains a safe working temperature for the shaft and bearings. Five thermocouples measure surface temperature at various locations.
The motor on flywheel energy storage should have the following basic characteristics: The motor is required to have high speed and output power. The design specifications of the YASA motor are shown in Table 2. Figure 1 shows the external characteristic curve of the motor.
As the core component of the flywheel energy storage system to realize the mutual conversion between electrical energy and mechanical energy, the performance of the motor directly affects the performance of the entire flywheel energy storage system.
After the first test phase, nine more stationary flywheel storage systems will be added to reach a capacity of 100 kWh. The stationary flywheel mass storage systems from Levisys use rotary vane pumps of the DuoLine, HiPace turbopumps as well as vacuum gauges to generate and measure the needed vacuum conditions.
The results of several experimental and numerical investigations demonstrated that a 40 % reduction in the operating pressure can reduce the flywheel surface temperature and windage loss by 20 % and 30 %, respectively. Consequently, a partial vacuum environment can achieve better energy conversion efficiencies.
