Abstract
An end shield is provided, particularly for electrical machines, which because of its design in sectors can be used to vary the natural system frequencies of the electric machine and foundation.
Claims9
An end shield for an electrical machine, comprising:
- sectors coupled to each other, a first one of the sectors having a different design from a second one of the sectors, a natural frequency of the electrical machine being varied on site by rotating the end shield in a plane perpendicular to an axis of the electrical machine.
An end shield for an electric machine, comprising:
- sectors coupled to each other, a first one of the sectors having a different design from a second one of the sectors, a natural frequency of the electrical machine being varied on site by rotating the end shield in a plane perpendicular to an axis of the electrical machine while the end shield remains installed on the electric machine,
- wherein the first one of the sectors is formed of a material that is different than a material forming the second one of the sectors.
A device for varying a natural frequency of an electrical machine comprising:
- an end shield including sectors, a first one of the sectors having a different design from a second one of the sectors, the natural frequency of the electrical machine being varied on site by rotating the end shield in a plane perpendicular to an axis of the electrical machine.
