Applications of Electric Drives

Where the mill shaft runs at a speed too low to permit economic flywheel design, the flywheel should be mounted on the pinion shaft of the gear unit in which case the peripheral speed of the wheel can be relatively high, and the weight correspondingly less, but the gears must be large enough to transmit the peak loads to the mill.
