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
Output Power
Rotary Motors
Power Output [W] = Torque [N·m] * Angular velocity[rad/sec]
Linear Motors
Power Output [W] = Force [N] * Linear velocity[m/sec]
Rotary or Linear Motors Power Output [W] = Bemf [V] * I(rms) * 3
Power Loss = 3 * I(rms)^2 * R(line-line)/2
Power Input = (Power Power Loss) / EfficiencyFactor
DC Brush Motor
Power Output [W] = Torque [N·m] * Angular velocity[rad/sec]
Power Loss = I(rms)^2 * R
Power Input = (Pout + Ploss) / EfficiencyFactor
Linear Motor
Power Dissipation [W] = MotorCurrentPeak[A] * TotalBusVoltage[V] * 3 / 2
Power Input = (Power Dissipation) / EfficiencyFactor
