What are the types of motor enclosures?

Ten Common Types of Motor Enclosures

  • Open Drip Proof (ODP)
  • Totally Enclosed Fan Cooled (TEFC)
  • Totally Enclosed Air Over (TEAO)
  • Totally Enclosed Non-Ventilated (TENV)
  • Totally Enclosed Force Ventilated (TEFV)/ Totally Enclosed Blower Cooled (TEBC)
  • Weather Protective 1 (WP1)
  • Weather Protective 2 (WP2)

What is the difference between TENV and Tefc?

Totally Enclosed, Fan-Cooled (TEFC) Motors have an external fan which circulates outside air to the motor. Totally Enclosed, Nonvented (TENV) Motors do not have air openings. While air does not freely move between the inside and outside, the motor’s construction is not air- or liquid-tight.
