High Temperature Motors

At high temperatures, the principal failure mode is winding insulation failure and the resulting short circuit that occurs. To combat this problem, high temperature magnet wire rated to 180∞ C is commonly specified. Non-copper magnet wire that is protected with exotic insulation materials is used when the application involves temperatures over 200∞ C. Dry lubrication is used to avoid material loss.

Recent High Temperature Applications:

  • Furnace operation
  • Industrial baking
  • Engine testing

A step motor isn’t just a step motor anymore: more and more applications require that their inherent design reflect the operating conditions present. While these reliable motors are still the workhorse for many general motion control needs, their range has also extended into hostile application environments that have expanded their value, giving the design engineer a new “old” tool.
