What type of surrounding enclosure is generally found on a DC motor?

Which type of motor enclosure is best?

When considering which motor enclosure is best, look at the type of cooling the motor requires and most importantly the environment that the motor will be operating in. Open Drip Proof – ODP motors are almost always the least expensive of all motors which often times makes them the preference of equipment OEM’s.

What is TENV enclosure?

Well – the answer is simply the motor is Totally Enclosed, and Non-Ventilated. Based on NEMA (National Electrical Manufacturers Association) definition, TENV states that the motor housing is fully enclosed and is not ventilated with a fan. The motor is being cooled unassisted (natural convection cooling).

What does motor enclosure ODP mean?

An open drip proof or ODP motor is a type of motor that typically runs cooler and does not overheat. Due to the fact that the chamber has open vents and air can flow directly over the windings, this open drip proof motor tends to be slightly more efficient because the windings are cooler.

Are motors rated NEMA?

NEMA Ratings for Motors. Is a motor, just a motor? No, not really, but if you want consistency, and the right motor for the right job, you better get up to date with the associated standards. NEMA offers three individual standards for motors: NEMA Insulation Classes, NEMA Frame Assignments, and NEMA Motor Enclosures.

What is Tepe motor enclosure?

A Totally Enclosed, Fan-Cooled (TEFC) electric motor is a type of industrial electric motor with an enclosure that does not permit outside air to freely circulate through the interior of the motor. An external fan blows outside air over the frame of the motor to cool it.

What is the difference between Tefc and TENV Motors?

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.
