Google it!

You know the criteria you've got to match, we don't!

For every one you admonish to do their own work, ten more will come and ask you to make them intelligent.

Do we know the criteria that the motor is required to meet?

The simple answer is no, we don't!

Re: Type of Motor Enclosure

well , I can only explain for TEFC and CACA, which can be used for one type of motor

TEFC- totally enclosed fan cooled, means for a type of motor which has a difference between inner and outer air for cooling. The motor lamination is totally closed in the stator housing and it is cooled by a flow of inner air (with rotating inner fans), and the heat exchange is through the pipes or ribs (or through water exchanger on the top). Pipes can be around the stator housing or in the heat exchanger on the top of the motor.

CACA- cooled air, cooled air - lamination is cooled with inner air (primary air), and secundary air is going through the pipes ( heat exchanger).

so, one type can be TEFC CACA....

TETV, I haven't heard about this one but totally enclosed it is....
