DC Motor Calculations: Calculating Torque | MICROMO

Calculating TorqueSpeed Curves. One commonly used method of displaying motor characteristics graphically is the use of torque – speed curves. While the use of torquespeed curves is much more common in technical literature for larger DC machines than it is for small, ironless core devices, the technique is applicable in either case.

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 ofrpm is required for a mains frequency ofHz. [4]. The solution is to use a gear unit. Gear units convert rotational speed and torque and transmit high power.

Research of iron ore grinding in a vertical-roller-mill ...

Two Swedish magnetite iron ores were comminuted with a pilot scale vertical-roller-mill. In these experiments the mill parameters dam ring height, grinding pressure and separator speed were varied, according to a factorial design of experiments. Thereby it is possible to generate polynomial regression models for each dependent variable.
