The following equations apply equally to a magnetic engine or
a purely electrical device. For a purely electrical device,
substitute (Power Fed Back to Input) for (Alternator Output).
Without losses (Efficiency = 1.0):
Output Power = COP * (Power Supplied by the Operator)
When closed-looped (alternator and engine efficiency = 1.0):
Output Power = (COP - 1) * (Alternator Output)
Alternator Output = (Output Power) / (COP - 1)
Power Rating = COP * (Alternator Output)
Power Rating = COP * (Output Power) / (COP - 1)
With losses (Efficiency < 1.0):
Output Power = COP * (Power Supplied by the Operator) - Losses
When closed-looped:
Loss Ratio = Losses / (Alternator Output)
Output Power = (COP - 1 - Loss Ratio) * (Alternator Output)
Alternator Output = (Output Power) / (COP - (Loss Ratio) - 1)
Power Rating = (COP - (Loss Ratio)) * (Alternator Output)
Power Rating = (COP - (Loss Ratio)) * (Output Power) /
(COP - (Loss Ratio) - 1)
Output Power = (Power Rating) * (COP - (Loss Ratio) - 1) /
(COP - (Loss Ratio))
