Abstract
Technique for reducing bearing current discharges in a system by increasing the surface area between the shaft and the frame of the system and thereby increasing the rotor to frame capacitance.
Claims17
An electromechanical device comprising:
- a frame;
- a bearing assembly;
- a rotatable member;
- a support member secured to the frame, the support member having an enhanced surface area;
- and
- a voltage reducing member secured to the rotatable member for rotation with the rotatable member, wherein the voltage reducing member is disposed between the bearing assembly and the support member.

A kit for modifying an electromagnetic device, the kit comprising:
- a first member configured to be slidably positionable along a shaft of an electromagnetic device;
- and
- a second member configured to be positionable along the shaft, wherein the first and second members form a capacitive enhancement mechanism which increases capacitance between the shaft and a housing of the electromagnetic device.
A system for reducing voltage between elements of a rotating machine, the system comprising:
- a frame;
- a bearing assembly;
- a rotatable member;
- an internal cap;
- and
- a voltage reducing member secured to the rotatable member for rotation with the rotatable member, wherein the internal cap and the voltage reducing member comprise a capacitive enhancement mechanism which increases capacitance between the rotatable member and the frame.
