Why large UV printer needs to use servo motor, Now let’s look at the difference between the stepper motor and servo motor:<\/p>\n

What are the defects of the stepping motor? The price is cheap, the control is simple, cannot operate precisely; The power itself is small, resulting in slow speed. Low level of technology, Plus the poor quality of the parts, the life of the servo motor is only one third.<\/p>\n

Servo means “follow” control signal. The basic concept of the servo is accurate, accurate and fast positioning. The role of the server to the motor is to provide a controllable voltage, a control voltage signal with a 90-degree difference between the voltage phase and the excitation voltage. The structure of the servo motor is different from that of ordinary motor, with encoder feedback closed-loop control, fast response, and accurate positioning.<\/p>\n

What are the advantages of servo motors?<\/p>\n

    \n
  1. Precision: closed-loop control of speed, position, and torque.<\/li>\n
  2. Speed: the rated speed of the servo motor can reach 2000~3000.<\/li>\n
  3. Adaptability: strong overload resistance, able to withstand three times the rated torque.<\/li>\n
  4. Timeliness: the dynamic time of motor acceleration and deceleration is short, generally within tens of milliseconds.<\/li>\n
  5. Stability: the operation is stable at low speed, and the stepping operation similar to the stepping motor will not occur at low speed.<\/li>\n
  6. Comfort: heat and noise are significantly reduced.<\/li>\n
  7. Operation: the servo motor stops running when the power is off; The stepping motor is unable to stop immediately due to some inertia, there will be out of step phenomenon.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
