In order to adapt to the processing technology of the coil, the automatic winding machine needs to be equipped with the spindle speed control function. The winding equipment should be processed by the type and the configuration is also different. The types of spindle motors that we are more familiar with include AC motors, DC motors, and servo drives. For the three types of motors, the speed control methods used by these motors have their own characteristics. The following will discuss the speed control methods in the equipment in conjunction with the winding equipment:
1. Speed control method of AC motor: This kind of motor itself has no speed control function, it needs to realize the speed control function through electromagnetic speed control device or install inverter. In winding equipment, we are more common in the inverter. Speed regulation mode, through the control system of the winding equipment to control the frequency converter so that the motor has a speed regulation function, this method also has a certain energy-saving effect.
2. The speed control method of DC motor: DC motor needs to convert the supplied power into DC power to drive the motor. Therefore, DC motors are equipped with DC speed control boards or brushless drives to drive and control the motor. Because the size of the motor is small, it is small The application volume is relatively large in winding equipment.
3. Servo drive motor speed regulation mode: it is a precision moving part suitable for high-precision winding equipment, and is used with a dedicated drive to achieve closed-loop operation control. This type of motor* is characterized by constant torque and closed-loop operation. To meet the processing requirements of high-precision coils.
