Synchronous motor soft start Unlike other electric motors, synchronous motors require special design consideration for critical motor characteristics such as transient startup oscillating torque and its torsional frequency. Typically, oscillating torque is controlled and handled by using a torsionally damped elastomeric coupling or even by oversizing the entire drive system to withstand high peak torque. Reportedly, the economical alternative to typically used techniques, the Safeset Autoreset coupling, offers increased reliability, minimum maintenance and maximum machinery protection. The coupling comes at a lower capital
