Electromagnet for Class C Applications

Electromagnet for Class C Applications
our newly developed Class C Electromagnet Uses Mineral Insulation

SINFONIA TECHNOLOGY CO,. LTD. turned to various types of mineral insulation material and inn ovative construction to successfully develop a Class C electromagnet with heat-resistant properties that are far superior to those of conventional Class H magnets.

• Mineral Insulation Material
  Conventional organic insulation (used on Class H magnets) can only withs tand temperatures up to about 200_C. By using inorganic varnish and electri cal wire covered with mineral insulation, our magnet can operate with a coil temperature of up to 300_C. (Class C applications).
• Possible to Use Large Currents
  Compared with conventional Class H magnets, the Class C magnet can accomm odate a wider range of currents.
• Withstands Higher Temperatures
  Compared with a conventional Class H magnet with the same performance capa city, the Class C magnet can operate under higher temperatures.
• More Compact System
  Higher heat resistance means that only air cooling is needed, which improves safety and makes maintenance easier.
