Replace normal motor with PM motor
- Project NameReplace normal motor with PM motor for air conditioner fan of thread spinning factory
Project Information
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.
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 factory required the installation of an inverter for the overhead crane. Song Nguyen conducted a survey, provided consultation, and installed the Yaskawa GA700 inverter for the factory’s crane to enhance system efficiency and protect the motor.
The system using Bonfiglioli inverter often had problems during operation, Song Nguyen consulted and replaced it with Yaskawa inverter for the factory.
The factory needed to replace a damaged Fuji inverter. Song Nguyen conducted a survey, inspected the issue, and installed a Yaskawa E1000 inverter as a replacement. After the inverter replacement, the factory’s system operated smoothly and efficiently.
The system was using an old Danfoss VLT5000 inverter model that has been discontinued, leading to high maintenance costs and a shortage of replacement parts. Song Nguyen conducted a survey, provided consulting, and replaced it with a Yaskawa A1000 inverter, helping the system operate more stably, reduce costs, and improve operational efficiency.
The old pump system required an additional pump. Song Nguyen conducted a survey, provided consultation, and installed the additional pump system, including a new pressure alternating control panel and remote control. After the installation, the pump system operated smoothly and efficiently.
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.
