Specific embodiments and principles:
the middle layer of the multilayer PCB board can not pass larger current, but the single-layer double-sided PCB board can pass larger current, and the key is the single-layer double-sided PCB board which can meet the connection requirement of the coil.
Due to the requirements of the motor stator on the magnetic field: the magnetic field directions of adjacent stator slots are opposite, namely: the direction of one slot is the S pole and the direction of the adjacent stator slot must be the N pole. The polarity change of the small motor is realized by wiring of a multi-layer circuit board, and in order to reduce the layer number of the PCB,
this patent adopts:
the 2 groups of coils which are connected in series are welded on the PCB after the head and tail ends of the coils in the 2 nd slot are manually exchanged, so that the polarities of the adjacent slots are opposite. Adjacent 2-slot stators of the slots of the servo motor 12 are respectively connected in series to form a double star connection, see fig. 3 and 4; the PCB is quite smooth in connection, and the single-layer double-sided PCB can be used for connecting the motor grooves.
When the coil is welded with the single-layer double-sided PCB, the welding device shown in figures 6-7 is used, and is characterized in that after one welding position, the rotating motor 2 is required to start to work, so that electrons rotate for a certain angle to weld the next position, and when the rotating motor 2 is electrified to work, the electromagnetic coil 11 in the telescopic driving mechanism 7 is electrified to generate magnetic force at the same time, so that the metal plate 12 moves forwards, the welding machine 5 is pushed to move outwards through the telescopic rod 15, and the stator is separated. After the rotating motor 2 works well and is powered off, the electromagnetic coil 11 is powered off simultaneously, and under the action of the spring 14, the baffle 13 drives the telescopic rod 15 to reset, so that the welding machine 5 returns to the welding point position again for welding.
Based on the above, the double star connection method is formed by adopting a single-layer double-sided PCB and connecting adjacent 2 slots of the stator 12 slots of the servo motor in series respectively. The magnetic field directions of adjacent stator slots are opposite, and the single-layer double-sided PCB can be used for connecting motor slots and can pass high current.
