Abstract

This chapter is presented as a guide to engineers who require electrical prime movers for their mechanical drives. It deals with the various existing specifications, sizing requirements, and the ventilation and enclosure of electric motors. It is the ultimate responsibility of the final user to specify the operational requirements and prevalent environmental conditions in as much detail as possible in order that the motors eventually supplied will perform satisfactorily. For this reason the basic conditions which can influence the type and size of machine are outlined.
