TEMPERATURE CONTROL SYSTEM FOR A PERMANENT MAGNETIC SYSTEM

摘要

A temperature control system for a permanent magnet system having at least one magnetic assembly, which is mounted in thermal contact with a yoke via a plurality of thermoelectric heat pumping devices, and having at least one temperature sensor connected to an electronic control circuit, said thermoelectric heat pumping devices being connected to and controlled by said electronic control circuit which controls the current passing through said thermoelectric heat pumping devices in dependance upon the temperature, so that the permanent magnet assembly is maintained at a desired temperature enabling the permanent magnet system to generate an accurate magnetic field. The temperature control system assures a constant temperature of the permanent magnetic material, essential for accurate magnetic field for a permanent magnetic system.
