May 27, 2008 So motor torque = T/i x efficiency. After i decided the required speed i found that i=35 and efficiency 0.65 as you advised me. So motor torque = 523.26/35x0.65=23Nm Taking a safety factor of 2 this torque becomes 46Nm. So the required motor power P=Txn/9550, where T=46Nm and n=N/i=1400/35=40RPM (speed at the gearhead output shaft) P=0.193Kw.احصل على السعر
Mar 09, 2006 If I ever need to calculate approximate conveyor power, for example on simple in-plant inclined conveyors, I often do the following simple calculation. Power = t/h x lift x 2.72 x 1.3 kW From this you can easily calculate the torque, if you have the speed and pulley diameter from the following: Torque = 9.55 x power divided by pulley rpm kN-mاحصل على السعر

May 06, 2017 Linear speed times force = rotational speed times torque You know everything but the torque so you take rotational speed onto the other side to get the torque: Torque = linear speed times force / rotational speed (not forgetting the 2pi in my other post and to convert rpm into revs per second) That should do it.

Once you determined acceleration torque, to calculate the total torque for your motor add your frictional torque + acceleration torque. Usually, you want to add a safety factor of around 1.5-2 depending on what's available on the market.احصل على السعر
