[0013] Specifically, the speed control circuit includes a first relay J1 and a second relay J2 provided inside the six-bit counter controller. The first contact of the first relay J1 is connected to the first contact of the second relay J2 and is commonly connected to one end of the first resistor R1. The other end of the first resistor R1 is respectively connected to the anode of the first diode D1 and a fixed end of the adjustable resistor W1. The other fixed end of the adjustable resistor W1 is connected to the cathode of the second diode D2. The cathode of the first diode D1 and the anode of the second diode D2 are both connected to the second resistor R2 and the timer discharge end DISC. The adjustable end of the adjustable resistor W1 is connected to the third contact of the first relay J1. The first contact or the third contact of the first relay J1 is connected to the second contact of the first relay J1, the second contact of the first relay J1 is further connected to one end of the first capacitor C1, the timer threshold input terminal THR and the timer trigger input terminal TRIG, the other end of the first capacitor C1 is grounded, the second relay J2 is further provided with a second contact and a third contact, the second contact of the second relay J2 is respectively connected to the anode of the first diode D1 and a fixed end of the adjustable resistor W1, the second contact of the second relay J2 is further connected to the first contact or the third contact of the second relay J2, and the third contact of the second relay J2 is also connected to the open circuit.

[0014] Specifically, the source of the switch tube Q1 is grounded and connected to the anode of the fourth diode D4 , and the cathode of the fourth diode D4 is connected to one end of the third resistor R3 and the gate of the switch tube Q1 .

[0015] Specifically, the power switch is connected to one end of the fuse, the other end of the fuse is connected to the anode of the sixth diode D6, the cathode of the sixth diode D6 is respectively connected to the cathode of the fifth diode D5, the motor and the input end of the three-terminal regulator U2, and the anode of the fifth diode D5 is respectively connected to the motor A and the source of the switch tube Q1.

[0016] Working principle: The power switch provides 18V / 2A DC power supply to the circuit system. The voltage is supplied to motor A after passing through the sixth diode D6, and then reduced to 12V by the three-terminal voltage regulator U2, and then supplies power to the speed control circuit; Motor A is connected to the six-bit counting controller through a bidirectional Hall device. The bidirectional Hall device detects the magnetic field changes of the motor and converts the magnetic field signal into an electrical signal and transmits it to the six-bit counting controller, realizing the bidirectional counting function of the forward and reverse turns of electrode A; the automatic deceleration turns value and the automatic stop turns value are set by the six-bit counting controller. The automatic stop turns value is the total number of turns that the coil needs to be wound, and the automatic deceleration turns value is set to The number of turns required to be wound is set to 100 turns less than the total number of turns required; the coil assembly is wound at a high speed when it starts to be wound, and starts to slow down when the automatic deceleration turns value is reached.
