STPiXA2206C On-Board Controller and Power Supply

The STP-iXA2206C Maglev turbo-molecular pump utilizes a magnetic bearing and motor drive system and has an ultimate pressure of 10-9 Torr. This integrated controller series can be fully interfaced with advanced controllers to operate on a wide range of applications and processes. It eliminates the need for a conventional, rack-mounted controller and interconnecting cables. The fully integrated product offers easy installation and small footprint as an all-in-one solution for all application tools. The rotor is entirely suspended by magnetic bearings so all contact between the rotor and the remainder of the pump is eliminated. As well as giving very low vibration, the elimination of contact means no bearing wear and no requirement for consequent pump maintenance. The STP-iXA2206C can be connected directly to a terminal using a serial port and the STP-link Monitoring Software. The Software Displays, Rotational Speed, Motor Status, Temperature, Rotor balance status and Magnet bearing current.
