Capacitor start, these currents will suddenly appear a peak, and then will be very slowly reduced to a very small value, then this value will leakage current, there is a general thing called leakage, then these voltages need to be increased slowly from 0 directly to a relevant value, and will lead to leveling off, which led to the damage of the capacitor.

1. Servo drive motor speed regulation

Servo motor it is used in recent years on the automatic winding machine, it belongs to the kind of more suitable for high-precision winding equipment, precision moving parts, it is with a special drive to realize the closed-loop operation control, and the most important feature of this kind of motor is the constant torque, as well as the closed-loop operation, used to meet the requirements of a variety of high-precision coil processing.

2、DC motor speed control mode

At present, we often see the following two types of DC motor brushless and DC brushless. DC motors also need to convert the power supply to DC to drive the motor. Therefore, DC motors are equipped with DC speed control boards or brushless drivers to drive and control the motor. And because of the small size of the motor, it is larger in small winding equipment.

3、AC motor speed control method

AC motor this is our most common motor, and this kind of motor itself is no speed control function, it needs this electromagnetic speed control device or installation of frequency converter to realize the speed control function, and in the winding equipment we often see is the frequency converter speed control mode, but through the winding equipment control system to control the motor with speed control function, this way to energy saving has a certain effect.
