hey /diy/ !
I just got a 1/2hp 120v motor (circa 1980/90ish?) that came with a recipricating scroll saw of the same time period (it's the good shit).
Unfortunately I'm having issues finding out how to wire the thing, or what cap to use, etc.
Most things I've been finding are for 5 wire motors, but mine has only 3 fast on connections.
The specs as written on the motor casing:
FSP PART NO. 88004
D397 MFG MODEL NO. C2490
1/2HP 115 VAC 60 CYL / 8.5 AMPS
1725/1140 RPM TYPE S P CLASS B CONT.
E-10250 RPGAY THERMALLY PROTECTED BK

Looks like an old motor fan a washing machine.
it has 2 speeds, the connector in the middle ist ground / neutral. only connect the live wire to one of the other inputs at a time.

take a volt meter and check continuity with those connectors and the bare metal case. zero resistance is the ground connector. the other 2 are your 120vac connectors. It really does not matter which one is black and which one is white.
you probably do not need a capacitor.

Hooked it up live and neutral and it went no problems. Its. Common and 2 speeds i believe, looked like different speeds but i wont know till i get the thing attached.
Thanks!
