1. a kind of control system of electric clippers, including for sensing the sensing device of trigger station and receiving sensing device signalController, it is characterised in that the sensing device be provided with least one station Hall stroke plate and it is matched slidablyMagnet thereon, magnet is fixed on the magnetic receiver in trigger frame, and magnetic receiver one end is fixedly connected back-moving spring, the other endIt is connected with trigger, magnetic receiver is slidably received in trigger frame, the Hall stroke plate is provided with four stations, is sequentiallyThe switch Hall position of arrangement, big opening stop Hall position, small opening and stop Hall position and closure Hall position, and the controller includesOne driving plate for being provided with signal acquisition module, Logical processing unit and motor drive module;

  • Corresponded to not on the Hall stroke plateBe connected with the signal acquisition module in driving plate with the signal output part of station, the motor drive module with drive electric clippersMotor connection;

    Described control system also includes a servo conversion processor, and the input of servo conversion processor is connected with direct currentSource, the output end connection three-phase alternating-current servo motor of servo conversion processor, servo conversion processor is also connected with and third gear is controlledSwitch, respectively starting switch, rotating forward switch and reversal switch, starting switch are used to control the running status of total system, whenStarting switch is in when enabling position, and circuit system is connected, and DC voltage is input into servo conversion processor by dc source, is passed throughServo conversion processor, DC voltage is converted to exchange output by direct current input, drives three-phase alternating-current servo motor, makes three to intersectThe phase of flow servo motor three starts simultaneously, no matter can rotate forward switch with invariable power, permanent torque output to reach motor low speed highIt is positive for driving three-phase alternating-current servo motor, drive scissors bit to perform closure or expansion action, reverser is for drivingDynamic three-phase alternating-current servo motor is rotated backward, and drives scissors bit to perform the shear action opposite with rotating forward.
