Kilowatts to horsepower
|Kilowatt (kW)||=||Horsepower (HP)|
Generator capacity required for direct start (DOL) three-phase motors
|Motor horsepower (HP)||=||Required generator capacity (KVA)|
Note: Just fill in the data in the blue area in the table below.
1. Fill in the horsepower (HP) of each motor starting line by line according to the starting sequence of the motor. (If starting all at once, add all the horsepower.)
2. Select the method for each startup (direct startup or step-down startup).
3. Press the "Calculate" key.
The generator capacity you need will be displayed in the column.
* Note: The above calculation is only a rough estimate, because there are many factors that have not been considered. Such as: use environment, motor efficiency, and heat loss.
