May 10, 2019 The ideal location for the drive of a belt conveyor is the place which minimizes belt tensions both during the acceleration and running periods. Although circumstances may dictate that a drive be located somewhere between the ends of a conveyor, locating it at the head end when the conveyor has to be powered to drive it is preferred.
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.

The calculation is actually quite simple. If the speed reduction of the chain or belt drive is N1, then the gearmotor output speed should be N times the speed calculated for the conveyor roller and the torque output should be 1/N times the torque calculated for the conveyor roller.
A further object of the invention is to provide an improved form of torque arm reducer drive for a conveyor belt, in which a torque arm reducer has direct connection with the roller for driving the conveyor belt and the drive to the reducer is located between the edge of the belt and the inside of the reducer so as to more uni- I formly distribute the drive loads and to avoid the necessity

Location For Backstop Installations. A low-speed backstop generally refers to units that are running at conveyor drive pulley speeds. Most frequently, low-speed backstops are mounted directly on the extended head pulley or drive pulley shaft opposite the drive, as shown in Fig. 3. This provides the most positive means of controlling belt reversal.
