The "full load speed" is the speed at which a motor has been designed to turn - usually measured in RPM (revolutions per minute) - when it is delivering its full rated output power.

Is governed speed the same as full load rated power?
yes
What is the runway speed of a hydraulic turbine?
Runway speed is the speed at full opening of guide vanes at nominal head and no load on Generator
How the dc current shunt motor change from no load to full load efficiency?
decrease in starting and running torque and speed is almost constant from no load to full load. it's because the field voltage is consant and current is varied.
What is the reasons for the slight decrease in the speed of the motor from no-load to full load?
Without going into the math, the change in speed increases the torque the motor can supply. The further the motor speed and supply speed are apart (known as the slip), the greater the torque will be.
Why does the speed of the DC series motor rise to a run away condition if full voltage is applied while there is no load?
At no load, the speed of a series motor rises to a run-away condition if the full voltage is applied because the applied voltage appears directly at the terminals of the motor and drives it to a run-away condition since speed is proportional to the voltage.
What is the speed of DC series motor at no load?
No load speed is the speed that the motor run when it has no load, i.e., the motor is separated from the engine, that speed is than greater than the rated speed, because the rated speed is the speed whwn the motor are linked to the load and it is the full load.
Full load torque of induction motor?
full load torque is the torque which produces rated power at full speed
What is full load?
The "full load speed" is the speed at which a motor has been designed to turn - usually measured in RPM (revolutions per minute) - when it is delivering its full rated output power.
Is governed speed the same as full load rated power?
yes
Why is motor current draw lower at full speed?
Because full speed is unloaded. As you load the motor, speed decreases, and slip increases, with an accompanying increase in current.
What is the runway speed of a hydraulic turbine?
Runway speed is the speed at full opening of guide vanes at nominal head and no load on Generator
How the dc current shunt motor change from no load to full load efficiency?
decrease in starting and running torque and speed is almost constant from no load to full load. it's because the field voltage is consant and current is varied.
Where is the best place to look to find specific information about a motor such as horsepower voltage full load current service factor and full load speed?

What is speed loading?
The "full load speed" is the speed at which a motor has been designed to turn - usually measured in RPM (revolutions per minute) - when it is delivering its full rated output power.
What is speed regulation and state the formula?
Speed regulation is the percentage of speed change, generally this is only calculated on devices which are attempting to maintain a constant speed. For example, on some industry motors, they need to maintain a constant RPM. When the motor has weight bearing on it, it is called a load, and the speed may change slightly. Formula: high speed (or no load) = nL Lowest speed (or full load) = fL (nL - fL) / fL x 100 = % regulation. example: 1700 rpm no load, 1500 rpm full load. (1700 - 1500) / 1500 x 100 = 200 / 1500 x 100 = 0.1333 x 100 = roughly 13% speed regulation.
What is the reasons for the slight decrease in the speed of the motor from no-load to full load?
Without going into the math, the change in speed increases the torque the motor can supply. The further the motor speed and supply speed are apart (known as the slip), the greater the torque will be.
Why you use throttle valve in steam engines?
Athrottle valve controls the flow of steam to the engine. Without throttling the steam the engine will simply run full speed and vary in speed as the load increases and decreases. The throttle valve maintains a steady speed by opening as the load increases and closing as the load decreases.
