Pole core

A method of producing a direct current motor having a pole housing and a field winding, the method comprising the steps of making a pole core having a central pole body and pole lips formed of one piece with said central pole body and extending from opposite sides of said central pole body so that said pole lips are connected resiliently and springily with said central pole body;

• and arranging said pole core so that the pole lips which are resiliently and springily connected with said central pole body, press the field winding against the pole housing in an elastic springy manner without additional spring elements.

A direct current motor, comprising a pole housing;

• a field winding arranged in said pole housing;
• and a pole core having a pole housing and a field winding, said pole core comprising a central pole body mountable on an inner side of the pole housing and pole lips which are formed of one piece with said central pole body and extend from opposite sides of said central pole body so as to press the field winding against the pole housing, said pole lips being resiliently and springily connected with said central pole body so that the field winding is pressed by said pole lips which are resiliently and springily connected with said central pole body, against the pole housing in an elastic springy manner without additional spring elements.
