Mr. Busche, I am assisting others in doing research on the potential for a fractional horsepower electric motor to catch fire after a locked rotor situation occurs. In the course of my internet research I came across the Virtual Conference Hall live compliance talk that occured in early 1996, the web address being (http://www.rcic.com/cnf/emc-pstc/1996/list401.htm) <http://www.rcic.com/cnf/emc-pstc/1996/list401.htm)> . Some of the things posed in that talk were of interest and in line with the research being performed. In general, we have a situation in which a fractional horsepower electric motor was the driving force in a powered attic ventilator that was itself manufactured in the early 1980's. The PAV was installed within a residential structure for a number of years, approximately 13-15. We believe that a locked rotor situation occured, caused the motor to overheat, (during which time the thermal protective device was either bypassed or was otherwise caused to fail), thus causing components within the motor and PAV to achieve a state that ultimately began the fire. The fire itself was contained to the attic area of the residence in question but,unfortunately, serious burn injuries were inflicted upon at least one individual as a result of this fire scenario. I would like to exchange with you further on the subject of the situation, if you would be so kind. I am looking into any possible leads that could help in our understanding of the possibilities. Any specific knowledge of a substantially similar sitation would be of use. If this in not something that you can do but you know of another or others that could share advice, please feel free to pass that information along also. It would be appreciated if you would respond to this message. My name is Eric. Thank you for your time Mr. Busche. ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com <http://www.hotmail.com> ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
