A good example is a drum-type hoist, where the torque required varies with the load on the hook, but not with the speed of hoisting. An example is shown in Fig. 11.7

    Variable torque loads include most centrifugal and axial pumps, fans and blowers and many mixers and agitators. As the speed is decreased, the torque will decrease by the square of the speed decrease and the horsepower required decreases by the cube of the speed decrease. As an example, when the speed of a variable torque load is reduced by 50%

    To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r) . If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.

DC motors are relatively simple machines: when the load on the motor is constant, speed is proportional to supply voltage. And when supply voltage is constant, speed is inversely proportional to the load on the motor
