Section 4.3 - VSI driven Synchronous Motor Drives
ratio is maintained constant at all frequencies (speed). Note that this is very similar to the case of the induction motor supplied from a V/f invrter. Near base speed, the motor back emf Ef and V1 are much larger than the voltage drop in the stator resistance, so that the above conclusion is quite valid near the base speed (base frequency).
V speeds - Wikipedia
V-speed designator Description V BE: Best endurance speed – the speed that gives the greatest airborne time for fuel consumed. [citation needed]V BG: Best power-off glide speed – the speed that provides maximum lift-to-drag ratio and thus the greatest gliding distance available.: V BR: Best range speed – the speed that gives the greatest range for fuel consumed – often identical to V md.

V-Belt Drive Selection Handbook - Baldor
If the speed ratio is < 1 (ex. 1:4), we refer to a speed up system; if the ratio is > 1 (ex. 4:1 ), it's a speed reduction system. In both cases, the ratio is obtained using the dimensions of the input drive (driver) pulley and the output (driven) pulley. In the following ratio, RS is the speed ratio, D1 the diameter of the driver pulley, D2 .

Oct 10, 2008 · The following is an example of how power-to-heart rate ratio percentage of change is calculated. The same method is used for running by substituting speed for power. Determine power-heart rate ratio for first half of ride: Power average = 180 watts, Heart rate average = 135 bpm. First half power-heart rate ratio = 1.33 (180 / 135)
Tip-speed ratio - Wikipedia
The tip-speed ratio, λ, or TSR for wind turbines is the ratio between the tangential speed of the tip of a blade and the actual speed of the wind, .The tip-speed ratio is related to efficiency, with the optimum varying with blade design. Higher tip speeds result in higher noise levels and require stronger blades due to larger centrifugal forces. = The tip speed of the blade can be calculated .

The improved performance is the result of smaller steps between each ratio, maximizing engine power under acceleration, while a wide 7.39 overall gear ratio spread and a lower numerical top gear .
AC2 - Space Vector PWM VSI Induction 3HP Motor Drive .
At t = 1 s, the speed set point is changed to 1500 rpm and the electromagnetic torque reaches again a high value so that the speed ramps precisely at 1800 rpm/s up to 1500 rpm under full load. At t = 1.5 s, the mechanical load passed from 11 N.m to -11 N.m, which causes the electromagnetic torque to stabilize at approximately at -11 N.m .
VSI V-Ball Series | Industrial-Grade Ball Valves | Kele
The VSI V-Ball Series is a unique, industrial-grade valve with temperature, pressure, leakage, and close-off ratings that far exceed those of standard commercial grade valves. The V-Ball Series assures positive low-leakage control in higher pressure systems such as those with variable speed pumps.
All about Horsepower, Torque, speed, and acceleration.
The lower gears have underdrive ratios, like 3:1, meaning you'll have greater torque (and thus greater acceleration), but a lower top speed since the engine revs higher than the wheels.

How to calculate a gear ratio ? – x-engineer.org
Your source of power is let say an electric motor. Between the motor and the pump we fit the gear reducer. How do we calculate the gear ratio ? If you need to amplify the motor torque with a factor of 3 then you need a gear reducer with a 3.0 gear ratio. In order to calculate the gear ratio of the two meshed gears we need to know either:
