Tip Speed Ratio: How to Calculate and Apply TSR to Blade ...

Understanding Tip Speed Ratio By definition, TSR is the speed of the blade at its tip divided by the speed of the wind. For example, if the tip of a blade is traveling at 100 mph (161 kph) and the wind speed is 20 mph (32 kph or 9 m/s), then the TSR is 5 (100 mph/20 mph).

How to Calculate Speed Ratio | Sciencing

If you know the speed ration and the speed input, you can calculate the speed output using the formula output speed = input speed ÷ speed ratio. For example, if you have a speed ratio of 3, and the input gear revolves at 180 rpm, work out 180 ÷ 3 = 90.

The motor's rotor position and speed is monitored in real time via a resolver or digital encoder to determine and control the motor's actual speed, torque, and power produced. By controlling the inverter section in response to actual load conditions at the motor in a real time mode, superior torque control can be obtained.

The Difference Between Low Gear Ratio & High Gear Ratio ...

High ratio gears are the opposite; the pinion has more teeth than the ring gear. So if the ring gear has five teeth while the pinion has 10, the ratio is now 2:1. For every one time the pinion spins, the ring gear spins twice to keep up, which is good for speed but not power.
