Identify Motor with odd shaft
Identify Motor with odd shaft
(OP)
Attached is a picture of a motor I bought at a Habitat Re-Store. It is made by Westinghouse and the nameplate indicates it is 1/3 hp, 1000 rpm, 115 v, 60 cycle, single phase, 4.6 amps - Model # C1021142-1. The direction is reversible and I am not sure about the duty cycle. The nameplate says "HRS. INT. " I plan to use it for about 10-15 minutes at a time to spin a hub with magnets mounted to the hub (magnetic tumbler for small jewelry pieces). The shaft is 1/2" exiting the housing and then is machined to resemble four twisted strands. I would like to attach a die cast aluminum hub to the shaft. The hub has a hole for a 1/2" shaft with a set screw.
What might have been the original use for the motor and why the odd shaft? A search of the model number and a search of the Westinghouse site did not yield any meaningful results.

Was this possibly used on some kind of reduction gear?

You are judged not by what you know, but by what you can do.

I'd call it a helical spline.
Since the motor is reversible, I'm guessing that the spline fits into a complementary hub that slides/is driven axially in different directions depending on the rotation direction, and then engages some kind of friction clutch, or maybe a dog face clutch, in an assembly where the thrust is mostly self-contained, not reacted through the motor bearings except while changing state. It's the sort of motor I'd expect to find in a washing machine.
Just clean the spline, overmold it with a filled epoxy, and machine the result down to 1/2" diameter, by running the motor and filing the epoxy down until it fits nicely into the pulley you have. Always stop the motor before fit checking.

The device will not have much starting torque, and likely drove a relatively "light" load in its original OEM application.
A flow of air past/through the motor will allow it to run continuously.
Any kind of load other than "light" will drag the device down.
Study the performance attributes of a Shaded Pole motor, and you'll have a pretty good idea of what to expect from this device.

The common method of reversing a shaded pole motor is to take it apart, reverse the stator, and reassemble it.

Despite the name tag photo being blurry, it looks like a direction arrow indicating
clockwise rotation (as viewed from the shaft end) just above the words "thermally protected".
With the wiring diagram being blurry, it's difficult to note its meaning.
(Is it a switch, a run capacitor, duel voltage connection? etc.)
I still suspect it's a shaded pole motor given the motor's construction style/appearance.
A better photo of the paper name tag would be more revealing.

When the motor is energized the helical spline disengage a friction clutch to elevate the load and when the motor was off the load weight engages the friction clutch to hold it in place ... or something like that

Right above the "Thermally Protected" line is a Cap. #, which is unreadable, but indicates this is a cap start motor, not a shaded pole. The cap does not appear to be attached, which also lead me to believe shaded pole, but on OEM equipment like washing machines, they would often put the cap somewhere else, and instead of a centrifugal switch it may have used a potential relay. But that shaft is definitely the type used on old washing machine motors. In Rev, it engaged a clutch that would spin the drum, in Fwd is when it extended the shaft to engage the pump, saved them from using two motors.
