Introduction Ndrive HPe 10/20/30
1.2.1. 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. An EfficiencyFactor of
approximately 90% should be used in the following equations.
Brushless Motor
Output Power
Rotary Motors Pout [W] = Torque [N·m] * Angular velocity[rad/sec]
Linear Motors Pout [W] = Force [N] * Linear velocity[m/sec]
Rotary or Linear Motors Pout [W] = Bemf [V] * I(rms) * 3
Ploss = 3 * I(rms)^2 * R(line-line)/2
Pin = SUM ( Pout + Ploss ) / EfficiencyFactor
DC Brush Motor
Pout [W] = Torque [N·m] * Angular velocity[rad/sec]
Ploss = I(rms)^2 * R
Pin = SUM ( Pout + Ploss ) / EfficiencyFactor
