Read more →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).

Read more →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.

Read more →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.
