Three Phase Variable Speed Drive Controller 18.5KW AC Motor Frequency Inverter
Description of frequency inverter
ST310 inverter series is a powerful high-performance current vector inverter, which can realize the control of asynchronous motor, V/F control mode, one machine with multiple functions, can realize multiple frequency switching, and can be used for textile, Drives for automated production equipment such as papermaking, wire drawing, machine tools, packaging, and food.
Product Testing for variable frequency drive
Semi-finished product testing
After all semi-finished products are processed, the quality
department will carry out a comprehensive appearance test and
electrification test. After the test is completed, professionals
will apply three layers of three-proof paint, and some products
will undergo electrification aging test.
All test data are archived to ensure the consistency of product
testing. Abnormal test data can be recalled and investigated later.
The finished product testing
At least 12 hours after the production is completed, the aging
temperature is 55 degrees to ensure the reliability of the internal
electronic components.
After the aging is completed, load tests such as loading, impact,
rapid acceleration, and deceleration are carried out with the
excitation motor, and the input and output ports of the product are
tested to ensure the consistency of product performance and various
functions
