Working Principle

The working principle of 1301850076 is based on the principle of a DC motor. It is divided into a power system, a control system, a DC drive and a monitoring system. The power system is composed of three-phase AC, rectifier, filters and ripple filters. The rectifier consists of a semiconductor bridge and a controlled resistor. The powerful semiconductor module can make the output current within the range of 0-100%, so as to make the motor run uninterruptedly and achieve the purpose of variable speed. The control module is composed of the amplifier stage, the voltage forming phase and the current forming phase. Through the comparison of the input signal and the output signal of the voltage forming phase, the current entering the control module is controlled. The trigger pulse generated by the trigger pulse generator is used to form the voltage forming signal, and the control capacity of the motor is realized. In addition, the monitoring system also has a remote monitoring and fault diagnosis function, which can be used to monitor and alarm the parameters of the system.

All in all, 1301850076 VFDs have a wide range of applications and are well suited for various engineering and industrial applications.
