Abstract
The invention is directed to a cooling system for a electric machine. A reliable tightness with respect to the coolant to be used is ensured with respect to the machine to be cooled as well as with respect to the ambient. The cooling arrangement is convenient and does not constitute a hindrance in the event that repair or maintenance work must be conducted on the machine. The electric machine includes a stator and a cooling jacket defining a hollow interior and having an inlet opening and an outlet opening for connecting the cooling jacket to an external cooling circulating system for facilitating a flow of coolant through the interior. The cooling jacket has a hose-like configuration and is made of a flexible, elastic material so as to cause the cooling jacket to lie in close intimate contact with the stator to facilitate a transfer of heat from the stator to the coolant. The cooling jacket is made of rubber or silicone.
