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 output speed, the ratio is K, the speed of the gear box to slow down in strict accordance with the reduction ratio, lossless
(4)Gear box of the motor torque constant KT by K proportion increased. Geared motor torque constant is KT2 motor torque constant KT1 multiplied by the total number of teeth gear box ratio K, multiplied by the efficiency of the gear box & eta; , that is,
KT2 = & eta; 2KKT1
（5)The efficiency of the gear box for
& eta; 2 = KT2 / KKT1
