Description of variable frequency drive
A frequency inverter is an electronic device which enables the conversion of an electrical variable ‘current’
In this case, the frequency inverter transforms an AC current with a certain (fixed) frequency into a voltage
with variable amplitude and frequency. In short, this results in a voltage conversion. Frequency inverters can
power a wide variety of equipment, such as: three-phase motors, pumps and air-conditioners.
In three-phase motors, the speed and torque of the AC motor can be controlled by varying the frequency.
This control does not restrict the performance of a three-phase motor, it just improves its efficiency.
Such motors are often used in industrial environments, and are especially common in the drive technology field.
Hardware design advantages of variable frequency drive
1. Panel knob adopts encoder knob, high-speed precision, stable speed, long service life.
2. The operation panel adopts the latest design idea, which makes disassembly and installation more convenient and reliable.
3. Standard network ports are used to connect the control board and operation panel. Signal transmission speed is high
and the distance is long.
4. One communication port 485, supports Modbus protocol, RTU mode.
5. The heat dissipation fan adopts temperature control to ensure effective heat dissipation and prolong the fan life.
6. The fan partition is removable and can be pulled out directly. Easy for users to carry out daily maintenance.
Thus extending the service life of the machine.
7. Choose the cooling fan with long life and large air volume, effectively reduce the temperature rise of frequency converter,
and ensure the reliable and stable operation of products.
8. The wiring terminal is designed to be a pull-out partition, which is convenient to install when wiring. After connecting the
line,insert the partition board and evenly divide the line class.
9. The bottom of the low-power machine is equipped with the installation size drawing, and the whole series is
equipped with the mounting hole position of 1/1 proportion paper shell template, so as to achieve more convenient
and fast installation of electric cabinet.
Working principle of variable frequency drive
The first stage of a Variable Frequency AC Drive, or VFD, is the Converter. The converter is comprised of six diodes,
which are similar to check valves used in plumbing systems. They allow current to flow in only one direction;
the direction shown by the arrow in the diode symbol. For example, whenever A-phase voltage (voltage is similar to pressure
in plumbing systems) is more positive than B or C phase voltages, then that diode will open and allow current to flow.
When B-phase becomes more positive than A-phase, then the B-phase diode will open and the A-phase diode will close.
The same is true for the 3 diodes on the negative side of the bus. Thus, we get six current “pulses” as each diode opens
and closes. This is called a “six-pulse VFD”, which is the standard configuration for current Variable Frequency Drives.
