Abstract
A female contact element for a slip ring motor with a power output >1 MW. The female contact element is configured for engagement with a male contact element to make an electrical connection between the female contact element and the male contact element. The female contact element is made of a Cu—Be-alloy.
Claims20
A slip ring motor with a power output of >1 MW, comprising a female contact element, the female contact element including
- two contact portions defining a slot therebetween, and
- a retraining unit restraining movement of the two contact portions, wherein the restraining unit is made of steel,
- wherein a plurality of projections project from free ends of the two contact portions,
- wherein the restraining unit engages the plurality of projections,
- wherein the female contact element is configured for engagement with a male contact element thereby making an electrical connection between the female contact element and the male contact element when providing the power output of >1 MW, the female contact element comprising a Cu—Be alloy,
- wherein a corresponding contact portion of the male contact element is insertable into the slot,
- wherein the two contact portions of the female contact element spread apart elastically when the corresponding contact portion of the male contact element is inserted into the slot thereby making the electrical connection, and
- wherein the two contact portions comprise the Cu—Be alloy.
