Project information
The old motor was running with a variable frequency drive at 35Hz. After Song Nguyen installed the Permanent Magnet (PM) motor and adjusted the speed accordingly, the result was a 24% reduction in electricity consumption.
Other projects
The Cau Bo lifting system uses 2 ACS800 frequency converters (discontinued) to synchronously control the position of 2 winch motors. Song Nguyen has replaced the new model ACS880 frequency converter, reinstalled the control program and changed the PLC program communication address to connect with each other.
The original system used DC motors with high maintenance costs, expensive and rare spare parts. Song Nguyen consulted and supported the conversion from DC motors to AC motors, helping the factory save on maintenance costs and spare parts for DC motors as well as DC drives.
The system using Bonfiglioli inverter often had problems during operation, Song Nguyen consulted and replaced it with Yaskawa inverter for the factory.
The system uses an old Danfoss VLT5000 inverter (discontinued), with high maintenance costs and rare spare parts. Song Nguyen advised and replaced the Danfoss VLT5000 inverter with a Yaskawa A1000 inverter for the factory.
The factory is facing the problem of old HMI, no longer visible and temporarily stopped production. Song Nguyen came to survey and upgraded to the latest Mitsubishi HMI and edited the interface to be larger, clearer and easier to operate.
The yarn spinning factory is using conventional motors for air conditioning fans. Song Nguyen has advised on switching to PM permanent magnet motors to help save energy, increase durability and optimize motor performance.
