Once you determined acceleration torque, to calculate the total torque for your motor add your frictional torque + acceleration torque. Usually, you want to add a safety factor of around 1.5-2 depending on what's available on the market. For example, if the sum of your friction torque and acceleration torque is 10Nm you would want a motor that could handle at least 15Nm-20Nm.

2 Conveyor Systems are mechanical devices or assemblies that transport material with minimal effort. While there are many different kinds of conveyor systems, they usually consist of a frame that supports either rollers, wheels, or a belt, upon which materials move from one place to another. They may be powered by a motor, by gravity, or manually

20.01.2016If we have a look at the motor power formula, we see that the speed of a motor (shown as rpm) directly effects the power of a motor; HP = (t x rpm) / 5252. Where; HP = Horsepower (1HP = 0.7457kW) t = Motor torque. rpm = Motor speed. 5252 = James Watt's original test data of 33,000 / 2π. So the simple answer is whenever you reduce the speed
