(2) Dependent on total output power: efficiency increases with increasing output power.
1.1.1. System Power Requirements
The following equations can be used to determine total system power requirements. The actual
power required from the mains supply will be the combination of actual motor power (work), motor
resistance losses, and efficiency losses in the power electronics or power transformer.
Use an EfficiencyFactor of approximately 90% in the following equations.
Brushless Motor
Power Output = Torque · Angular Velocity ; Rotary
= Force · Linear Velocity ; Linear

· 3 ; Rotary or Linear
Power Loss = 3 · I

Power Input = (Power Power Loss) / EfficiencyFactor
DC Brush Motor
Power Output = Torque · Angular Velocity
Power Loss = I

· R
Power Input = (Power Power Loss) / EfficiencyFactor
