How Electric Motors Work
The voltage is less as one phase is always in reverse. We can calculate this by 400Volts divided by square root of 3 which is 230Volts. As the voltage is less, the current will be too. If this coil also has an impedance of 20 Ohms, then 230Volts divided by 20Amps =11.5Amps.

Flywheel Energy Storage
This results in the storage of kinetic energy. When energy is required, the motor functions as a generator, because the flywheel transfers rotational energy to it. This is converted back into electrical energy, thus completing the cycle. As the flywheel spins faster, it experiences greater force and thus stores more energy.
