How to Measure Electric Motor Torque Sciencing

Torque refers to the rotational effect produced when force is applied to an object and is measured in Newtonmeter (N.m) in metric system, or poundfeet in U.S. system. Electrical energy, measured in watts, can be used to produce torque, and an electric motor is a good example of electrical energy that can produce torque.

Torque Measurement in Wind Turbines HBM

Gear unit. In wind turbines, there is a "conflict of interests" between the rotor''s drive speed, limited, for example, by pitch speed, and the required rotational speed of the generator.With two pole pairs, a rotational speed of 1500 rpm is required for a mains frequency of 50 Hz. [4]. The solution is to use a gear unit. Gear units convert rotational speed and torque and transmit high power.
