Flywheel-induction-motor drive

MANY DRIVES with fluctuating loads must be equipped with flywheels in order to reduce the size of the motor required and the load peaks taken from the supply mains. This problem has been discussed in many papers and technical books, and it is obvious that the general-purpose induction motor cannot be used for flywheel drives. High-slip motors are most suitable as energy stored in the flywheel can be made available.
