A flywheel is heavy metal wheel attached to a drive shaft, having most of its weight concentrated at the circumference. Main function of flywheel is to reduce speed fluctuation by storing extra energy during part load as kinetic energy and same is released during overloading. By slowly increasing the speed of a flywheel a small motor can store up energy which enables the motor to perform a function for which it is ordinarily too small. Shaft calculations incorporate a high safety factor and are validated by bending and torsion stress analyses.p1

Designing & Construction Process of Flywheel: –

–           Fully machined & bored on VTL up to Zero oddness
–           Statically, Dynamically & Mechanically Balanced
–           Ultrasonically Tested (As per Requirement)  
–           All Sizes within the Blasting Range of the Material
–           Flywheel is designed taking into account maximum possible energy fluctuation Encountered in service
