CNC spring machine at present are to use the servo motor, the servo motor drive the CNC spring machine organism operation, and makes the organic composition of each part of the combination of coordinated operation, achieve production efficiency optimization.
   Servo motor is very important for CNC spring machine, then what is the servo motor? Servo motor, often referred to as the servo motor, a motor in the servo system to control the operation of the mechanical components, can be said to be a servomotor.
   Servo motor to control speed and position of mechanical components to achieve very high accuracy. In theory, the voltage signal into torque and speed to drive the control object. Servo motor can be divided into two categories: DC servo motor and AC servo motor. The DC servo can be divided into motor with brush and brushless motor; AC servo motor is a brushless motor, synchronous and asynchronous motor with the other, motion control in general use synchronous motor, the scope of its power, can do a lot of power.
   Servo motor plays a role in the overall operation play a decisive role on the CNC spring machine. For the 2/3 axis computer spring machine, with a spool, the cam shaft and screw pitch axis, with three servo motors, three can be independent or simultaneous operation. Using servo motor, so that the production speed CNC spring machine is improved, the stability has been consolidated, accuracy can effectively guarantee. For the 5/6 axis computer spring machine, using five / six servo motors, a wire feeding servo motor, upper / lower cutter servo motor, servo motor, 1 pairs of cam screw torque servo motor, the shaft can realize independent and synchronous operation. For NC 3/4 axis universal spring coiling machine, a total of four axis, that is to say the 4 servo motors, in particular to a cam shaft, a shaft rotating core wire, a shaft, a shaft curly (match). For the 12 axis without camshaft CNC spring forming machine tool axis, independently controlled by eight servo motors, that is to say knife 8 axis, plus line of a shaft, a shaft rotating core, a shaft, a rotating line curled shaft.
   Kaichuang spring machine R & D and CNC spring using machine production and marketing are the servo motor Yaskawa Japan Sanyo or production. Sanyo or servo motor Yaskawa, through long-term practice has also been recognized by the industry, the motor performance is relatively stable, customers and friends with more assured.
