Pa = absorbed power
Pm = nameplate rating of the electric drive motor (or generator) at the motor (or generator) rated base speed.
- These service factors SF are empirical values based on AGMA and ISO specifications and our experience.
They apply for "State of the art" designed driven machines and normal operating conditions.
They apply for electric motors as prime movers-if prime motor is a multicylinder combustion motor, 0,25 has to be added to the SF.
For multiple drives consider the actual load sharing.
Refer to us for special designed applications or special operating conditions.
