Abstract
The intake of dust and dirt-contained outside air into the motor during the cooling process causes the requirement of dismantling and clean-up operation once every three years. Besides that, high speed of acoustic noise isi produced by the cooling fan mounted on rotor at high speed. totally enclosed, airtight-type motor was developed not only to deal with the dust intake problem and thereby eliminate the requirement of periodical dismantling and clean-up operation, but also for noise reduction purpose. Large noise of internal cooling fan was decreased by newly developed uneven pitch blade fan.
