Totally Enclosed DC MOTORS

Motors are recomended for installation in dusty and highly moisturised atmosphere. In this type of motor, there is no direct contact between the internal air and the external atmosphere. Motors with different cooling arrangements as shown below are manufactured:

• Natural cooling without any cooling contrivance - upto 3.75 KW
• Self fan cooling by a fan and cowl mounted at one end of the motor.The cooling air passes over the surface which is normally having ribbed construction giving increased cooling area - upto 11 KW
• Force cooling by a small A.C. motor driven cooling fan (blower) cooling the surface of the motor - upto 30 KW
