This example describes the straw feed grinder control circuit,which can automatically control the working status of two electric motors. 　 The principle of circuit The straw feed grinder control circuit is formed by knife switch Q,fuses FU1,FU2,thermal relay,AC contactors KM1,KM2,time relays KT1,KT2, intermediate relay KA and control buttons S1,S2,which is shown in Figure 4-129. The main loop of cropping motor M1 is formed thermal components like the normal open main contact KM1-1,KR of Q,FU1,KM1. 　 The main loop of feed motor M2 is formed by normal open main contact KM2-1 of KM2 and Q,FU1,FU2.
