How to selection?
Knowing the required output torque of inner and outer shaft T2(in), T2(out), output speed n2(in), n2(out),
—– T2(out)÷η×n2(out)÷9549= P2(out)； T2(in)÷η×n2(in)÷9549= P2(in)。
Must be：P2(out)+ P2(in)≤P1；T2(out)×f1=T3(out)≤Tn2(out)；T2(in)×f1=T3(out)≤Tn2(in)。
Remark：T2(out)=output torque of outer shaft；T2(in)= output torque of inner shaft；n2(out)=output speed of outer shaft；n2(in)=output speed of inner shaft；
η= efficiency；P2(out)=output power of outer shaft；P2(in)=output power of inner shaft；P1=motor power；T3(out)=drive machine equivalent torque；
Tn2(out)=rated output torque of outer shaft（sheet 1）；Tn2(in)= rated output torque of inner shaft（sheet 1）；f1= drive machine loaded factor（sheet 3）
For example:
Knowing the required output torque of two output shafts T2(outer)=5000N.M；T2(inner)=2000N.M；output speed n2(outer)=20rmp；n2(inner)=30rmp。
Liquid mixer，work every day 16h，opposite rotation direction of inner and outer shaft
——-5000÷0.94×20÷9549=11.14KW； 2000÷0.94×30÷9549= 6.68KW。
11.14+6.68=17.82KW；5000×1.1=5500N.M；2000×1.1=2200N.M；
