- Looking for Definition of Rotor WR^2 1 - Eng-Tips
Wk2 is a particular “simplified” constant for moment of inertia It has “weight” instead of “mass” and it is used on the expression: t = Wk2 (rpmf - rpmi) (308*Tavg)] t = accelerating time in seconds rpmf = final rotating speed in revolutions per minute rpmi = initial rotating speed in revolutions per minute (normally zero at stand
- (WK^2) Weight Moment of Inertia? - Eng-Tips
Trying to figure out the minimum HP required to accelerate a fan (blower) wheel Nema publishes the Load Wk^2 values for motors at different RPM HP I have modelled the fan wheels in cad and have the inertial properties ie mass moment of inertia in the axis of rotation (Iz) Is this the
- Inertia Constant - Generator - Electric power transmission . . . - Eng-Tips
I am trying to calculate the Inertia constant of a generator for testing purposes using collected data I also have software that will model transient stability studies When I provide the model with the following information: H=2 MW = 50 MVA = 156 25 I recieve the following data, simulating
- Pump Runout condition? 3 - Eng-Tips
On startup the motor can drawin 250-300% FLA which supplies the torque to get it going There is an mass inertia factor (WK2) which determines how much torque you need If the application involved variable speed drives you would have to ensure you didn't exceed the breakdown torque I probably have you completely confused So mission accomplished
