Yaskawa frequency converter

Main uses:

Mainly used for three-phase asynchronous AC motor, used to control and adjust the motor speed.

How it works:

A frequency converter is a power electronic device that adjusts the speed of a motor by changing the frequency of the input power to the motor.

The basic working principle is to convert the power frequency power supply into DC power supply through the rectifier, and then convert the DC power supply into the AC power supply with adjustable frequency through the inverter to supply the motor.

Power Electronics:

Yaskawa drives use advanced power electronics such as insulated-gate bipolar transistors (IGBTs) and SCRS. The IGBT is the core component of the inverter, which has the characteristics of high input impedance and low output impedance, and can achieve fast and efficient energy conversion.

Main parameters:

Rated input voltage and frequency: Support a wide range of input voltage and frequency range, the common rated input voltage is 220V, 380V, 415V, etc., rated input frequency is usually 50Hz or 60Hz.

Rated output voltage and frequency: Power signals of different voltages and frequencies can be output according to needs, the common rated output voltage is 0-220V, 0-380V, 0-415V, etc., and the rated output frequency is usually 0-400Hz.

Rated output power: determines the maximum power of the motor that can be controlled, and the common rated output power is 0.4kW, 0.75kW, 1.5kW, 2.2kW and so on.

Control mode:

Support a variety of control methods, including V/F control, vector control, vector control with encoder, etc. Different control methods are suitable for different application scenarios, can meet different control requirements.

Protection function:

It has a variety of protection functions, such as overcurrent protection, overheat protection, phase loss protection, overvoltage protection, etc. When the inverter internal or external failure occurs, these protection functions can cut off the power supply in time to protect the safe operation of the equipment.

Application:

It is widely used in various occasions that need to adjust the motor speed, such as air conditioning load, crusher load, large kiln calciner load, compressor load, rolling mill load, winch load, etc.

Operation and maintenance:

Yaskawa inverter can be set by panel operation or special programming software, users can adjust the control parameters, protection parameters and monitoring parameters of the inverter according to actual needs.

In the process of use, it is necessary to pay attention to avoid exposure to high temperature, humidity or corrosive gases in the environment, to avoid the instantaneous impact of zero voltage, regularly check the running state of the motor and the heat dissipation of the inverter.
