Use a multimeter to measure the path and resistance. Then it can be divided into three groups, each with a different label. If you can recognize the second group, (for example, 1,1*; 2 、2*; 3,3 * like this), 1, 2,3, the heads are combined together, and the remaining three heads are combined together (two groups of three wires in each group are screwed together). Connect two groups (mechanical multimeter) with a milliamp multimeter and rotate the motor shaft. If your hands don't swing, the head and tail are right. If your hands swing a lot, it means your head and tail are wrong. Switch 1 and 1* and retest. If the pointer swings, reverse 1 and 1*, and then pour 2 and 2* on the watch, such as the pointer. At the same time, you can check the number of motor poles; After connection, the motor shaft can rotate, and the shaft rotation table is set only once for 2-pole motors and twice for 4-pole motors. Among them, analogy. The quality of the new wound motor can be seen by measuring the resistance. I hope it helps you.
