X7625B 27.4.28. SEQUENCE STARTER MOTOR K.{Mr Kilner} Motor cold, current on teazer 20 amperes. Volts across teazer = 7.65 1/2 " " main = .12 " " armature = 1.03 Total. 8.80 on 12 volts with the motor stalled the current was 29.5 amperes. Motor warm after 5 mins. run on the teazer at 12 volts - Current = 21.5 amperes. Motor speed = 285 r.p.m. With the armature stalled the current was 24.5 amperes. EFC/H.E.West. | ||
