Considering that you want to find out the maximum torque of the domestically used motors such as the motors of grinders, sewing machines , fans etc, using a practical approach at home, then how can it be done ?

any ideas ?

    We can find out torque using a electric generator type dynamometer. I think this is the most practical one.These are one type of dynamomoeters used for engine testing. If we are able to create a smaller one for measuring smaller motors.

    its simple, we know the power delivered based on present working conditions (Theoretical work done per unit time)by the machine, hence we can predict the value of torque even without using any Torque measuring devices.

    Keep in mind, I am not exactly talking about rated power as when the machine gets old, its power delivering capacity may reduce.

    Is this theoretical method of calculating torque, practical ?

    rated voltage x rated current = torque x angular velocity

    the rated voltage and current can be obtained from the motor tag. rpm can also be found in a similar way, else it can be measured by a tachometer.

    the angular velocity can be calculated from the rpm , using the formula:

    2x(pi)x(rpm)/60


    substituting all these values in the first mentioned equation, torque can be determined.

    what say ?
