ELECTRICAL MACHINE WITH RADIAL METAL PARTITIONS FOR DIRECTION OF COOLING AIR

摘要

FIELD: electricity.SUBSTANCE: invention offers electrical machine with cooling through radial slots in sheet pack (12) of stator and sheet pack (7) of rotor, at that main flow of cooling air from two sides along the axis is directed to sheet pack (7) of rotor and radially through slots in sheet pack (7) of rotor and sheet pack (12) of stator. Part of air flow passes also through heads (15) of winding. Housing (1) of electrical machine has an outlet (18) though which heated exhaust air can be drained. At closed sides of housing (1) of the electrical machine exhaust air should pass only in axial direction between axial ribs (11) till the end of sheet pack (12) of stator in order to be released in direction of open side of the housing (1). Metal partitions (10, 20) are installed in order to prevent barriers at the side of exhaust air and part of cooling air flow.EFFECT: providing the most effective direction of cooling air in air-cooled electrical machine.3 cl, 3 dwg
