How to embed four groups of embedded wires in stator main and auxiliary of single-phase motor? Answer: Four groups of main windings are embedded in the stator and evenly distributed into four poles. Just connect four poles along the first pole winding to form SNSNSN SN magnetic pole (or NSNS, that is, the opposite poles are the same) ... Please determine the current direction and magnetic pole direction with your right hand to check the correctness of the connection. Four groups of secondary windings and main windings are embedded with 90-degree electrical angle difference and evenly distributed into four poles. Four poles are connected along the secondary winding of the first pole to form the SNSN pole, and the secondary winding is buried (the primary winding and the secondary winding can be buried in the same layer). How to connect the main connector? Answer: The above answer has been said, that is, it is assumed that the current direction is from the head of the first winding (head in and tail out), the tail of the first winding is connected with the tail of the second winding (head in and head out), the head of the second winding is connected with the heads of the three windings (head in and tail out), and the tail of the third winding is connected with the tail of the fourth winding (tail in and head out). ..... At this time, after the embedding and wiring are completed (i.e., the distribution of magnetic poles SNSN is completed), the head of the first winding and the head of the fourth winding can be used as the lead-out ends of the main winding (the secondary winding is the same as the main winding, and both ends can be led out). Note: "Please check the correctness of the connection with the current direction and magnetic pole direction specified by your right hand", that is, open your fingers with your right hand and hold them vertically with your thumb. The direction of four fingers is the current direction of the coil and the direction of your thumb is the direction of magnetic pole N (north). Please ask my younger brother to learn some necessary electrical theory knowledge and guide maintenance practice with solid theory. Without the teacher's instruction, you will feel that the work in hand is always so simple!
