rotor speed उदाहरण वाक्य

Therefore, the term d? m / dt represents the deviation of the rotor speed from synchronism in rad / s.
This has the benefit that the rotor speed in the generator is constant, thus the frequency of the AC Voltage is fixed.
An unloaded squirrel-cage motor at rated no-load speed will consume electrical power only to maintain rotor speed against friction and resistance losses.
It is also necessary to modulate the throttle in conjunction with the pitch so that the model maintains a constant rotor speed.
Sensorless control requires derivation of rotor speed information from measured stator voltage and currents in combination with open-loop estimators or closed-loop observers.

The manual throttle may also be considered a flight control because it is needed to maintain rotor speed on smaller helicopters without governors.
An additional drawback stems from the high rotor speed of this type of pump : very bearings are required, which increase the cost.
where N is the rotor speed, P is the number of poles in the generator, and f is the frequency of the output Voltage.
In some cases, complete destruction occurs, e . g . body panels, fuel tanks, and engines are torn away, even at normal rotor speed.
The throttle setting must maintain enough engine power to keep the rotor speed within the limits where the rotor produces enough lift for flight.
