Background Overview

In the field of industrial washing machines, equipment needs to operate in various harsh working environments, including high humidity and high temperatures. The operating characteristics of industrial washing machines require inverters to have specific functions to ensure stable operation and efficient performance.

Load Characteristics

• During the washing process, the running frequency is around 10Hz.

• Heavy load at low frequency.

• Frequent switching between forward and reverse running.

• Occurrence of large surge currents.

• During the spinning-drying process, the running frequency is as high as 130Hz or higher.

• The working environment is usually high humidity and high temperature.
  

  
  

Requirements for the Inverter

• Soft start of the motor to reduce surge current.

• Stable operation at high speed.
  

  
  

KD600 Inverter Solution
