What is a DP motor?

An open motor in which the ventilating openings are so constructed that drops of liquid or solid particles falling on it, at any angle not greater than 15 degrees from the vertical, cannot enter either directly or by striking and running along a horizontal or inwardly inclined surface.

What does DP mean on a motor?

Dripproof/Open Dripproof (DP/ODP): Horizontal motor term indicating a machine in which the ventilating openings are so constructed that successful operation is not interfered with when drops of liquid, or solid particles, strike, or enter, the enclosure at any angle from 0 to 15° downward from the vertical.

How do I know if my motor is explosion proof?

An explosion proof motor is clearly marked with a nameplate that identifies its suitability for a given hazardous environment. Depending on the agency certifying the motor, the nameplate will clearly indicate the hazardous location Class, Division, and Group for which the motor is suited.

What is a totally enclosed air over motor?

Totally Enclosed Air Over/Airtight (TEAO)

This motor has a dust-tight frame or enclosure. It is typically installed in the airstream, and the air movement generated by the fan passes over the motor to provide cooling. TEAO motors would be used in areas with direct drive where the motor is in the airstream.

Can a Tefc motor be used outdoors?

A totally enclosed, fan-cooled (TEFC) motor is much more adaptable to outdoor locations and high moisture areas. With a bit of care, you can expect this type of motor to work well and have a long life.

Is DP same as transformer?

DP means distribution panel in a power supply system. … DP in the power supply system is different from the transformer, which can be called by different names according to construction, voltages, applications, cooling methods, etc.

What are 4 common types of motor enclosures?

The Most Common Types Of Electric Motor Enclosures

  • The most common types of enclosures are:
  • Open Drip Proof (ODP)
  • Weather Protected (WP1 / WP2)
  • Totally Enclosed Fan Cooled (TEFC)
  • Totally Enclosed Non-Ventilated (TENV)
  • Totally Enclosed Air Over (TEAO)
  • Totally Enclosed Forced Ventilated (TEFV)
  • XP (Explosion Proof)

Is a brushless motor explosion proof?

Regarding electrical ignition sources, explosion proof DC motors and associated electrical devices (i.e., wiring, conduits, connectors, etc.) … Explosion proof DC motors can be in any wiring configuration: brushed or brushless, permanent magnet or electromagnetic field.

Is a totally enclosed motor explosion proof?

TEFC motors are not secure against high pressure water nor submersible. They are also not explosion proof without additional modifications.

What type of motor is explosion proof?

An electric motor is considered explosion-proof when it is capable of containing an internal explosion without rupturing and putting the entire industrial facility at risk.

What is the difference between ODP and Tefc Motors?

An open drip proof or ODP motor is a type of motor that typically runs cooler and does not overheat. … On the other hand, a totally enclosed fan cooled, or TEFC motor has a closed off chamber which requires the use of an external fan to blow air over it.

What are the two 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 a WPI motor enclosure?

Weather Protected Type 1 (WPI) – As you might expect, the Weather Protected Type enclosures are for outdoor use. Their purpose is to prevent debris, dust, rain, and rodents from entering the motor.

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.

What is NEMA in stepper motors?

The National Electrical Manufacturers Association (NEMA) defines a set of standards used to dictate tolerances for many products, including step motors. Step motors are categorized by NEMA frame size, such as “size 11” or “size 23” or “size 34”.

What is C face motor?

A “C-Face” motor is a common American mechanical standard designed with a rugged flange on the face of the motor for mounting purposes. The weight of the. motor is supported by the flange, which is most commonly attached to a gearbox. The flange is strong enough to cantilever the motor.
