What is IC 411 cooling?
1. Cooling systems. Standard construction electric motors are closed and self-ventilated with a fan mounted to the motor shaft which operates in both directions of rotation. This cooling system, per IEC 60034-6, is designated IC411.
How do you cool a Tefc motor?
An external fan blows outside air over the frame of the motor to cool it. This motor is arguably the most commonly used motor in ordinary industrial environments. TEFC enclosed motors usually cost more than open motors, but offer increased protection against weather, dirt, and moisture.
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 IC81W?
IC81W– is air-cooled and self-ventilated, and the motor is equipped with a heat exchanger (air-to-water). The water circulation is powered by an independent pump or water system. IC86W– motor is a fully enclosed motor with independent air / water cooler.
How do I keep my electric motor cool?
Another method to remove heat from electric motors is by providing forced air cooling. This is commonly done by providing an electric fan to blow air over the motor. Force air cooling can reduce the amount of heat transferred into the machine structure and allow the motor to be operated at a higher load point.
How do fan motors stay cool?
Another common method for keeping electric motors cool is forced draught air cooling. At low speeds the fan, borne by the motor’s shaft, becomes inefficient so a forced ventilation is needed to deliver the volume of air required to cool the motor down.
Can a TENV motor be used outdoors?
These motors are suitable for indoor use and clean atmospheres. 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.
Can Tefc motors 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.
What is FLP enclosure?
An enclosure for electrical apparatus that will withstand, without injury, any explosion of the prescribed flammable gas that may occur within it under practical conditions of operation within the rating of the apparatus (and recognized overloads, if any, associated therewith), and will prevent the transmission of …
What is the IC code for motor cooling?
The three most frequently used motor cooling methods have the following IC designated codes according to the IEC 60034-6 standard: IC 410, IC 411, and IC 418 are applied.
What kind of fan does an ic666 motor use?
IC666 – Fully enclosed internal air circulation with independent fans; independent blower heat exchanger (air to air) on the motor.
What is the standard for cooling electric motors?
The IEC standard defines suitable methods for efficiently cooling electric motors. The three most frequently used motor cooling methods have the following IC designated codes according to the IEC 60034-6 standard: IC 410, IC 411, and IC 418 are applied.
What is the code for the cooling mode?
The code “IC” indicating the cooling mode, the subsequent letters and characteristic numbers respectively indicate the circuit arrangement of various cooling media, the pushing mode of the cooling medium movement, and the cooling medium. Common cooling medium markings: “air” is A; “water” is W.
