Power = Torque x Angular Velocity. Power = Voltage x Current. Torque = (Voltage x Current)/Angular Velocity. Given the equation above, we can see that it is possible to find the torque simply by measuring the volts, amps, and rpm of the motor. If we then change the load on the motor, we can find a second point on the curve.

approaching zero at zero speed, increasing as the square of the speed up to torque or some lesser required torque at speed. Typical curves are shown in Fig. 3. As a result, successful starting depends on having adequate torque at a point where the load torque becomes significant and approaches the output capability of the motor.

A hammer mill consists of a feeding unit, a number of hinged or fixed hammers connected to a rotating shaft inside milling casing, and a sieve to control the size of the product. The impact takes place when the hammer hits the feed material when they are passing through the little gap between the hammer and breaker plate as shown in Fig. .

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 m = 1 Nm.
