A nut torqueing device for a recessed nut is disclosed. The nut torqueing device includes a nut engaging assembly to engage a nut in a recess. The nut engaging assembly includes: a nut engaging element to engage the nut in the recess, at least one stackable riser element to stackably connect to one of the nut engaging element and an adjacent stackable riser element therebelow, and a transmission engaging element to stackably connect to an uppermost one of the at least one stackable riser element. A ratchet interface within the nut engaging assembly allows rotation of the nut engaging element in only one direction, while other stackable elements rotationally interlock. A low profile transmission extends within a small space to transmit rotational power to the nut engaging assembly. The nut torqueing device is applicable with a terminal nut of an electric generator.

Nut torquing device for recessed nut

A brush holder apparatus has a stationary support member having two opposing grooves, a fork electrical connector, and a conductive bar passing through a main body of the stationary support member. A brush holder is releasably affixed to the stationary support member, and has two rails that slide along the grooves. The brush holder's knife electrical connector mates with the fork electrical connector. A brush spring is clipped on the brush holder, and presses a brush against a collector. A brush lead connects the brush to a brush terminal. The brush terminal has a generally L-shaped body with a lower part thereof retained under a terminal compression plate, and an upper part thereof located on a front side of the terminal compression plate. The brush terminal is removed from or installed into a front side of the brush holder, and by hand or without the use of any tools.

Brush holder apparatus having brush terminal

Various embodiments include a brush holder apparatus. In one embodiment, a brush holder apparatus for receiving a brush includes: a first support member; a box member affixed to the first support member; and a cam member operably connected to the first support member, the cam member configured to retain the brush against an inner surface of the box member.

Brush holder apparatus

Various embodiments include apparatuses adapted to include a dynamoelectric machine rotor with a modified outer surface. In some embodiments apparatuses include a dynamoelectric machine rotor including a rotor body having a spindle, pole regions, the pole regions having a non-uniform radial distance from an axis of rotation of the rotor to an outer surface of the pole regions and a plurality of slots in the outer surface of the rotor body, the plurality of slots being spaced apart in a circumferential direction of the rotor body, each of the plurality of slots extending in an axial direction of the rotor body.

Rotor with non-cylindrical surface for dynamoelectric machine

A brush holder apparatus is disclosed. In one embodiment, the brush holder apparatus includes: a first support member; a second support member affixed to the first support member; a brush retainment member affixed to the first support member and extending substantially parallel with the second support member; and a cam member operably connected to the second support member, the cam member configured to retain a brush against the brush retainment member.

A system, method and computer program product for predicting collector flashover is disclosed. The method includes receiving a frame of measured data from a data acquisition system, fitting a statistical model to the measured data wherein the measured data includes a plurality of measured variables measured at multiple time instances. The statistical model and the measured data are used for estimating one or more parameters for the frame wherein the one or more parameters include at least one of field circuit impedance and field current noise. A flashover is predicted based, at least in part, upon the one or more estimated parameter for the frame.

Method and system for detection of collector flashover

An apparatus for holding a brush in contact with a moving conductive surface, the apparatus includes: a rotatable member disposed adjacent to the brush; and a spring coupled to the brush and to the member and configured to bias the brush towards the moving conductive surface; wherein the rotatable member in a first position makes contact with the brush to secure the brush from movement and in a second position releases the brush from the contact to allow the spring to hold the brush in contact with the moving conductive surface.

Pin-style collector brush holder with rotating spring plate, radial contact, and brush-wear indicator

An electrical generator having a stator assembly and a rotor assembly is provided. The rotor assembly has a rotor member, a first collector ring, and first and second rotor coils. The first collector ring is disposed proximate an exterior surface of the rotor member. The first collector ring has first and second balance resistors and first and second electrical terminals. The first and second balance resistors are disposed on an exterior surface of the first collector ring. The first and second balance resistors have first and second apertures, respectively extending therethough that are adjacent third and fourth apertures extending into the first collector ring. The first and second electrical terminals extend through the first and second apertures, respectively, and extend through the third and fourth apertures, respectively. The first and second balance resistors conduct first and second electrical currents to the first and second electrical terminals, respectively, that energize the first and second rotor coils, respectively. The first electrical current is substantially equal to the second electrical current.
