Calculate the Acceleration Torque Ta If the motor speed is varied, the acceleration torque or deceleration torque must always be set. The basic formula is the same for all motors. However, use the formulas below when calculating the acceleration torque for stepper or servo motors on the basis of pulse speed. Common Formula for All Motors

In order to find the maximum tension is necessary to calculate the effective tension, that is, the force required to move the conveyor and the load at a constant speed. The calculation of the total tension is based on a constant speed of the belt including the necessary basic conditions to overcome the frictional resistance and tension forces.

If you plan on driving your conveyor pulley directly by your motor shaft you do not need to consider it. The conveyor belt will always have some belt efficiency so this must be considered and it can be easily looked up. The above equations are mainly used to calculate the torque required by the motor due to frictional forces .
