For any particular conveyor, there will be a certain amount of power required to move its load. The power is developed by an electric motor and then transferred to the conveyor belting via gearboxes and drive pulleys. On longer conveyors, soft starting devices are included such as clutches, fluid couplings or variable motor speed drive controls.

The load shown by the dotted line in Fig. 6.10 is stable at speed X, for example: if the load torque increased from T a to T b, the load torque would be greater than the motor torque, so the motor would decelerate. As the speed dropped, the motor torque would rise, until a new equilibrium was reached, at the slightly lower speed (Y).

This means the drive keeps going with these types of overloads. Probably one of the best examples is a conveyor that is being loaded with dirt. Each time a new load of dirt gets dropped on the conveyor the motor sees this as a shock load, but has enough overload to keep going.

Nov 20, 2013· Gravity torque only needs to be considered when the belt is not mounted horizontally. It is a positive number when the load is moved upward, and a negative number when the load is moved downward. Equation 3: T GRAVITY (oz-in.) = r WLOAD sin φ. In our example, the conveyor is not inclined, therefore φ= 0°, which means that T GRAVITY = 0.

Since the conveyor is a constant torque load, the percent loading of the motor is directly proportional to the percent loading of the conveyor belt. Therefore, at load the motor produces 100 horsepower; at 50% load 50 horsepower, and at 10 percent load 10 horsepower.

Let's assume 1800RPM since that's what most conveyor motors at our plant are, and 480V 3phase across the line start. I guess I could start with calculating the torque required: torque = force x radius. Is the radius in question that of the conveyor roll? And force = mass x acceleration. Mass = 6000lbs. Acceleration = (1800 - 0)/t.
