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.

Get PriceTo find approximate RPM the old machinists would follow the formula: RPM=(CSx4)/D which is essentially the same as what we use today: RPM = SFM X 3.82 ÷ Tool Diameter, just without the division. The "SCS" ("SFM") is the cutting speed in feet per minute, 4 is a constant, and D is the diameter of the cutter So simply put: ply the SFM by 4 and then divide the result by D. Let's take an ...
