The main function of a fly wheel is to smoothen out variations in the speed of a shaft caused by torque fluctuations. . If the source of the driving torque or load torque is fluctuating in nature, then a flywheel is usually called for. Many machines have load patterns that cause the torque time function to vary over the cycle. .
