Electrical motor

摘要

The electric motor has a housing in the form of a spindle casing enclosing a stator and a rotor. A self-supporting cooling mantle (1) provides meandering cooling channels (2) extending in the axial direction of the stator. The cooling mantle is secured to the stator and the spindle casing via heat conductive connections, with deflectors at either end, for directing the cooling air flow in opposite directions. The cooling air connections are provided at one end or partway along its length.
