Product Overview

Description

       1. How to choose a suitable motor?
           The formula is :N.m=Reel pipe Radius(mm)*loading weight(kg)/100.

           For example, if the loading weight is 50kg ,and the reel pipe radius is                                 

           30mm,please figure out the torque of the motor. N.m=30*50kg/100=15N.m.

       2.How about the weight can the motor load?
          The formula is :Loading weight(kg)=N.m*100/ Reel pipe Radius(mm).

          For example: the torque of the motor is 15N.m,the Reel pipe Radius is 30mm                   

          please figure out the the loading weight.Loading weight(kg)=15N.m*100/ 30 Reel

          pipe Radius(mm)=50kg.
