Electrical machine has housing have inlet and exit side recesses so that cooling medium radially enters into inlet-side recess and axially flows to outlet-side recess through cooling channels and radially discharges from outlet-side recess

摘要

The electrical machine has housing (7) in which stator that has stator core (1) with stator winding (2), and radially surrounds a rotor (3) is arranged. The stator core has extending webs so that adjacent webs in tangential direction and housing form cooling medium channel (9). The housing has inlet and exit side recesses (10,10') formed in inlet and exit side end portion of stator core so that cooling medium radially enters into inlet-side recesses and axially flows to outlet-side recesses through cooling channels and radially discharges from outlet-side recesses.
