Hello all. My first time here.
I've got an old printing press that has a 110/220V AC motor. The name plate lists the following information:
General Electric Single Phase A.C. Varying Speed Electric Motor
Type: BSS546 4 1 1800
Form: 03
Voltage: 110/220
RPM: 900/1800
Number: 3756530
Patents; Various dates, the latest of which was April 1905
The motor includes a pedal rocker assembly attached by linkage to a cage of brushes surrounding a commutator that is part of the rotor. Operation the pedal moves the cage approximately 45 degrees of rotation around the commutator.
Wires to the brushes have been disconnected by parties unknown.
My initial research suggests that it is a "Repulsion" style motor. But troubling is that no mention of the word Repulsion is made on the name plate, and at least on all the on-line versions I've seen, GE lists 'Repulsion Motor" on the name plates. So I'm a little apprehensive assuming this to be a repulsion motor especially in light of the following:
The brush cage assembly has 4 brushes two of which are hard wired into the stator housing. the two which are wired are 180 degrees opposed to one another, while the other two are side by side at approximately 60 degrees and 120 degrees relative to the other two.
I could guess that this is a "Compensated" repulsion motor and the odd set of brushes are part of a compensating circuit, but I hate to make such assumptions. Especially since one of the wires to one of the brushes has separated, leaving a dangling end at each end, just begging to be rejoined togther.
But, before risking anything foolish I thought it wiser to seek expert help, wondering if any of you might have access to schematic info for such a motor specifying how the correct connections need to be made?
Further complicating this is that somewhere over the years someone has installed very out of place looking crimp-on spade terminal lugs to one of the non-wired brush assemblies( with no wires installed in the added lugs, however) making me wonder if the split wire was purposefully cut by someone intending to re route the wiring?
My main intent here is to try and understand the box stock schematic the way it was originally intended to be, so that I can comfortably ignore whatever the intent was of this later modifier.
thank in advance for any contextual help
