# Motor winding resistance and copper loss
# Scope: Copper resistive loss at supplied RMS current and winding resistance.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

current = 5 A
resistance = 0.5 ohm

loss := current^2*resistance [W]

check copper loss budget: loss <= 20 W

scenario alternative: current = 4 A
