The basic principles of the protection equipment for the protection equipment of the automatic winding machine? Basic principles of communication frequency operating: new frequency frequency technology is a technicality of changing the frequency of the switching power supply frequency through the frequency converter to change the power supply frequency, and then change the speed of communicating the speed of multi -threaded motor. The replacement to DC electricity is replaced through the frequency converter, and then the DC electricity is carried out to the replacement of communication through the inverter, and then the speed ratio of the communication motor is controlled. A amorphous three -dimensional rolling iron heart, non -crystal three -dimensional high and low pressure integrated machine

The automatic winding machine actively protects the control of the new project series series of the new project series of the inverter. Export the change of the frequency of the switching power supply.

The speed of the three -phase asynchronous motor is selected by the point frequency, the electrical pole pair and the rotation rate. The torque of the three -phase different step motor is caused by the influence of the magnetic flux of the motor and the middle of the current through the current. At the fixed frequency, if the operating voltage will inevitably reduce the frequency, then the magnetic flux is too large, and the magnetic control circuit is rich. When optimistic, damage motor.

Therefore, the frequency and working voltage must be a market share change, that is, the frequency of changing the frequency to control the voltage of the inverter, so that the magnetic flux of the motor is unremittingly inevitable, and the condition of the weak magnetic and magnetic vanguard is avoided. Because the universal inverter is generally controlled by V/F, that is, the transformer frequency frequency method is used, the frequency and working voltage are changed to make the better motor control method.

Therefore, the speed adjustment method of AC motor is picked up. AC motor speed adjustment is the adjustment method of changing the frequency of electric motor stator power supply, and then changing its synchronous speed. Its characteristics:

1. The overall planning is large, hard, and highly accurate.

2. High efficiency, there is no additional loss in the transmission link;

3. The overall planning is widely used, suitable for cage type asynchronous motors;
