SOWAKAM VFD use for Industrial washing machine

As the industrial washing machine pays more attention to energy saving and emission reduction, a new generation of fully automatic washing machines with variable frequency speed regulation has been developed.

SOWAKAM Electric independently developed vector inverter has won good feedback in the washing machine field for its high stability, high reliability, and excellent response time.

1. Composition and working principle of industrial washing machines

Industrial washing machines refer to large-capacity washing machines that have the functions of initial washing, washing, rinsing, bleaching and dehydration and can automatically switch between functions without manual operation.

The working principle of the fully automatic industrial washing machine is to control the motor to continuously perform forward and reverse rotation under the CPU scheduling management through the inverter to achieve asynchronous operation of water and clothes, so that the water and clothes can rub against each other to achieve the purpose of cleaning. It mainly has the following washing procedures:

washing--- Medium ---spin--- End ---Start--- Evenly ---High spin

2. Advantages of SW200 inverter as a transmission drive for washing machines

The transmission system is an extremely important component of industrial washing machines. It participates in the entire washing process because it mainly provides power support for washing machines. The transmission system consists of a motor and a frequency converter. During the entire washing stage, the frequency is automatically adjusted to achieve constant torque speed change without impact and intermediate transition (gearbox, speed change device or coupling, clutch) devices, which significantly reduces the energy consumption of washing.

The SW200 series vector inverter meets the requirements of high starting torque, multi-speed, and wide voltage range of industrial washing machines with its unparalleled performance and absolutely excellent cost performance; automatic slip compensation and fast and powerful communication methods and other technical difficulties, and stable performance can adapt to various complex high temperature and high humidity environments.

The use of advanced vector control technology makes the washing machine start smoothly, which can widely meet the needs of various customers.

X1/COM and X6/COM are the inverter start/stop and forward/reverse switching terminals (corresponding to the forward/reverse washing process).

Terminals X1, X4, X5, and X6 are digital signal ports, and the common terminal is COM, which means that they are effective when closed and connected with COM. X4, X5, and the combination mode (X4+X5) are the three multi-speed settings of the inverter, which correspond to the three washing processes of the washing machine: uniform distribution; medium dehydration; high dehydration.

R, S, and T are power inputs, and U, V, and W are connected to the motor.

KA and KB are relay outputs, usually connected to fault alarms.

P and Pr are connected to brake resistors (select accessories according to the inverter power).
