Cooling structure for linear induction motor

摘要

A primary of a linear induction motor has a plenum formed on its upper surface to receive cooling air from a fan. The upper surface of the core is formed with fins to promote cooling. Air flows from the plenum to side housings in which the end turns are located. A deflector plate directs air from the plenum over the end turns of the windings. Exhaust slots are provided in the housing above the end turns and a baffle between the housing and the end turns promotes flow through the end turns as it moves toward the exhaust slots.
