DESCRIPTION

16 ENCLOSURES 16a BLOWER VENTILATED, FULLY GUARDED (DPFG-BV)

For use on fully guarded motors where the application requires extended periods of low-speed operation by armature voltage control at full load torque. The amount of ventilating air is independent of motor speed, allowing constant torque operation with safe operating temperatures down to five percent rated speed with most power supplies. See application section page 5.3 for motor heating limitations. The standard blower motor is 230/460 Volt AC, 60 hertz and is suitable for (but not nameplated for) 220-240/440-480 Volt AC, 60 hertz. Refer to Wolong for 50 hertz blowers and special blower motor voltages. Filters are optional for applications requiring protection against particles in the air. For fine particles such as cast iron dust, a blower and filter is not recommended. For these conditions, totally enclosed construction or separate ventilation should be considered. Blower filters on frames CD5010AY and below are washable. Filters for frames CD6000-CD6900 are disposable. For use of splash - proof fully guarded on blower ventilated motors, see page 3.14, Item 16d. 16b SEPARATELY VENTILATED, FULLY GUARDED OR TOTALLY generator from an external source to the commutator end on frames CDL182AT-CD5010AY and to the drive end on CD6000 CD6900 frames. Openings have drilled and tapped holes for convenient duct connection. Price does not include blower, pipe or duct. See page 5.13 for separate ventilating air requirements. Separately ventilated motors with recommended air supply are suitable for constant torque operation with allowable operating ENCLOSED SEPARATELY VENTILATED (DPFG-SV) OR (TESV) For applications where a contaminated atmosphere is encountered, ventilating air is piped into the motor or

temperatures down to five percent base speed with most power supplies. See application section page 5.3 for motor heating limitations. On separately ventilated, fully guarded motors, air is expelled into the surrounding environment through air exhaust openings which are fully guarded. For use of splashproof on separately ventilated, fully guarded motors, see page 3.14, Item 16c. On totally enclosed separately ventilated motors, the ventilating air is ducted in and out of the motor and solid covers are placed on all other air openings. The motor is then inherently splashproof, and the addition of the splashproof modification to a totally enclosed separately ventilated motor is not necessary. Note: CD180AT motors must have an 8 1/2 C-Face. Totally enclosed separately ventilated CD180AT frames in hazardous locations are not available.
