# BLDC motor sizing estimate
# Scope: Mechanical power and approximate DC bus current at a supplied efficiency.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

torque = 1 N*m
speed = 3000 rpm
voltage = 24 V
efficiency = 0.85

shaftPower := torque*speed [W]
busCurrent := shaftPower/(voltage*efficiency) [A]

check bus current budget: busCurrent <= 20 A

scenario alternative: torque = 0.8 N*m
