Gear motor selection guide

In order to choose the most appropriate gear motor,it is necessary to understand the detailed

technical characteristics of the deceleration motor driven machine,you must define a using

coefficient of fB.Using coefficient of fB.The selection of electric vehicle motor gear motor first shall determine the following parameters:working hours a day; Start-stop times per hour; Cycle per hour; Reliability to O; Job machine torque T machine; The output rotational speed n; Load type; The environment temperature; The cooling conditions; Reducer is usually based on constant Torque,start stop not frequent,and design of room temperature. The www.dongfeng-motor.com allowable torque T be determined by the type:T=T out fB use coefficient X T-gear motor FB - reduction motor output torque using coefficient Transmission ratio(I)I=n into the P/n the motor power(kw)9550** n/P = T eta output torque T out(N.m)T=9550*P*eta/n type :n into - the input speed eta - reducer transmission efficiency When choosing gear motor,according to different working condition,must also satisfy the ac synchronous motor following conditions:1,2,T T a T work or machine machine type=fB*T always work :in fB - overall use factor,fB total=fB*KR fB1** KW fB - load characteristic coefficient,reliability coefficient KR - fB1 - environmental temperature The number; KW - cycle factor
