the 5 is pushed in. Then the one from the wound Stand 5 and the can 3 existing structural unit impregnated with impregnating varnish. Be there Cavities between your can and the winding are filled with impregnating varnish. At the same time results there is an adhesive effect between Soaltrohr3 and Stand 5.

A preferably made of plastic ivappe 11 serves as a protective cover for the Motor part of the heating water circulation pump

For the rotor 12, the shaft 13 of which drives the pump wheel 14, a bearing on one side is selected This results in a short mean turn length for the stator winding and that in the winding The resulting electricity heat losses are small.

Furthermore, the result is a short and material-saving design.

Bearing bushes 15 and 16 are in a bearing bracket 17 arranged, which is inserted into the can 3. In this way, a safe centering can be achieved of the rotor to achieve the stator.

In Figure 2, the end wall 6 'of the can3 opened by a central tubular extension 18. This is between the end connecting conductors 7 and 7 'passed through. Between winding parts and the adjacent parts of the can 3 is a Insulating layer 8 'arranged. In the extension 18 there is a sight glass 19, which from the seal 20 is surrounded and held by the snap ring 21.
