Answer Posted / kunal
Motors are generally cooled by three methods :
1. naturally ventilated: no special ventilation cooling by
natural conduction and radiation.
2. blower ventilated:
separate blower, with small external motor and filter
provided. which allows motor to accept additional external
air and force heated air out
3. separately ventilated motor:
separately ventilated by ducted air flow through the enclosure
