We repair, re-build and replace electronic variable drives: AC drives, DC drives and servo drives of all types and vintage. We service variety of brands including: ABB ACS600, ABB ACS800, Allen Bradley Power Flex 700, Bosch, Control Techniques, Fanuc, Infranor, MOOG, Okuma, Panasonic, Seidel Kollmorgen, Siemen, Stober, Yaskawa and many others. See examples here…..
Power converter designed to vary the speed of an ordinary induction AC motor. It converts f1 phase. The AC drive input AC voltage and frequency are fixed. The AC drive output voltage and frequency vary but the ratio of voltage to frequency is kept fixed allowing the drive to maintain, to a degree, constant output torque. The torque is constant only with motor speeds above 5HZ of the output voltage. Below 5Hz the output torque collapses and the motor stalls usually triggering an overload trip in the drive.
Allen Bradley Power Flex 700 Repair
This Allen Bradley Power Flex 700 was powering up a compressor. It failed during a power surge. The damage was in the power stack section. It has been repaired and power tested. At Data Factory we have spare parts as well as manuals, programming software, network interface modules, etc., needed to fix this type of drive.
ABB ACS800 is high power, high capacity AC drive. This particular drive was working in a critical part of a power plant driving a high power compressor. Due to a challenging working environment: high ambient temperature and frequent stops and starts, the drive failed destroying its power stack and bus bar system.
Mains synchronised power converter used to control speed of shunt or series exited DC motors. It is going out of fashion, replaced by the Vector drive but still very popular in legacy applications.
Siemens Simoverg Repair
Simoverg is a Siemens drive made in mid 1990s. This was likely the first attempt to build a DC drive with a digital interface. The client is still running a production line where a few of these drives are installed. We have developed a technique to re-build them so they can run for a few more years.
Eurotherm 590 Repair
Eurotherm 590 DC Drive is a modern design. It is no longer in production but it is still very popular as a replacement for old analogue units. Due to compact design quite a few of them fit into a tight space in a switchboard.
AC Servo Drive: It precisely monitors the motor speed and toque in order to allow exact control of the motor speed. It requires special motors with speed feedback devices. Far more expensive than a Vector drive.
DC Servo Drive: It works on similar principal to AC Servo Drive but delivers far higher speed accuracy and much higher torque.
OKUMA VAC Spindle Drive Repair
OKUMA does not support spindle drives of this vintage. We offer comprehensive repair and rebuilt service. It extends the life span of this drive by 5 to 7 years. Typical turnover time is 3 to weeks.
STOBER Servo Drive
Data Factory excels in repairing and rebuilding exotic brands of electronic variable speed drives. STOBER drive, made in Germany is a good example.
Yaskawa Servo Drive
Yaskawa is a giant in the area of industrial automation. They make many diverse types of drives and other industrial gear.
