Sume punctum motorium maximam efficientiam ut obiectum studiorum designandi, primum rem intelligas Brushless motorem et calces reductionem Brushless motorem secundum proprietates mechanicas.

Take the motor point maximum efficiency as its object of study design, the first thing to understand brushless motor and gear reduction brushless motor in the relationship of mechanical properties of
(1)Brushless motor with gear box, equivalent to add an additional load, so the gear reduction of brushless motor current is bigger than ordinary brushless motor current some
(2)Gear reduction is to enlarge the output torque of brushless motor, the ratio is the reciprocal of gearbox reduction ratio K, but the torque will be loss
(3)Gear reduction can minish the brushless motor celeritas output, proportio est K, celeritas archa calces ad retardationem stricte secundum rationem reductionis
(IV) Capsula Gear torques motoris constantis KT per K augetur proportio. Aureus motor apparatus apparatus constans est KT2 Aureus motor assiduus KT1 multiplicatus secundum numerum dentium pixidem calces proportionis K, multiplicata per efficientiam archaη phaleris; hoc est,
KT2=η 2KKT1
（5) De efficacia archa calces pro
η 2 = KT2 / KKT1
