10-04-2009· Once you have all that you then need to consider when the motor is starting up, how fast you want it to come up to full speed as that will have a bearing on motor power and size. The inertia's and friction at start up plus the power to move the load will determine how much torque the motor needs to have and its susquent power rating.
13-05-2015· If you want to find load torque with respect to motor shaft, the steps are as below. The load torque is always understood as resistance torque. Load torque with respect to motor shaft = (Aforesaid torque) divided by { (Gear box ratio) x (Drive efficiency as a fraction of 1)}. Conveyor is composed of linear motion and rotary motion components.
