Stator housing arrangement for internal rotor motor of railway vehicle drive

摘要

The stator housing includes a stator laminations stack cast into the stator housing (1) and in which at least one tubular cooling hose (3), encircling the stator laminations stack for cooling, is integrated into the unit comprising the stator housing and the stator laminations stack. The helix of the tubular cooling hose (3) is cast into the lateral wall (4) of the stator housing receiving the stator laminations stack, with the tubular cooling hose specifically comprised of a metallic tube having an oval or flattened oval cross-section.
