Delta VFD-A frequency converter motor number of poles set
According to the actual needs of the motor
To provide the required power supply voltage, and then to achieve the purpose of energy saving, speed control, in addition, the inverter there are many protection features, such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, frequency conversion
The device has also been very widely used.
Variable frequency
Drive, VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment. The inverter is mainly rectified (AC variable DC), filter
Wave, inverter (DC variable AC), the braking unit, the drive unit, the detection unit micro-processing unit and so on. The inverter is used to adjust the voltage and frequency of the output power by breaking the internal IGBT.
The frequency parameters of the inverter motor are not set, because the inverter will automatically detect the number of pole pairs of the motor during operation, and it will not need to be set.
