When, the release of stop button TA, QC dead electricity is pressed, while TA normally opened contacts（What TA pins 3 and pin 4 were controlled）Closure, makes TC, SJ
Electronic work is obtained, the direct current after transformer T step-down rectifiers is electrically accessed motor M stator winding, start braking, reach setting time
Afterwards, the normally-closed contact SJ-1 that SJ time delays disconnect disconnects, and TC dead electricity release, braking procedure terminates, and TC simultaneously switches off the electricity of transformer T
Source.
In sum, the utility model motor braking controller uses three group relay QC, TC and SJ, makes inner control line
Road is simple, and reliable operation.
