How to know the motor power used by the coupling

       The main basis for selecting the coupling is the maximum torque transmitted. The maximum torque transmitted should be less than or equal to the allowable torque value. The determination of the maximum torque should consider the acceleration and deceleration torque and overload torque required for machine braking.However, it is often difficult to determine the maximum torque due to insufficient data or difficult analysis during design. At this time, it can be selected according to the calculated torque.That is, the calculated torque does not exceed the allowable torque value.The calculated torque Tc can be obtained by the following formula:
