They are the most common energy storage used devices. These types of energy storage usually use kinetic energy to store energy. Here kinetic energy is of two types: gravitational and rotational. These storages work in a complex system that uses air, water, or heat with turbines, compressors, and other machinery.
The stator magnetic field in a three-phase induction motor rotates around the air gap between the stator and the rotor. The direction of field rotation determines which way the motor turns and is controlled by the …
Like all electric motors, the synchronous motor converts electrical power into mechanical power. The primary difference in operation, however, is that the synchronous motor only delivers torque and power when it is running at synchronous speed. It is a true, constant-speed motor, providing the electrical frequency is constant.
