Roterande elektrisk likströmsmaskin samt rotor och rotorhärvstöd för en sådan maskin

摘要

The invention relates to a rotary electric direct current machine having a rotor (8) mounted on a rotor shaft (9) and being provided with axial winding coils, whereby the coil ends are supported by a generally ring shaped rotor coil support (7) that is centered with reference to the rotor shaft and is supported directly at the axial end of the rotor, adjacent the radially outer region thereof. According to the invention the rotary direct current machine is characterized in that the rotor coil support is provided with a surface area that is considerably enlarged in relation to its circumference. The invention also relates to a rotor for such a direct current machine as well as to a rotor coil support.
