Hi,

I'm a total rookie with electrical work and gear motors and need some help. I just bought a Dayton 1LPN7 gear motor from Grainger as part of a pig rotisserie build.

See link:

http://www.grainger.com/Grainger/DAYTON-AC-Gearmotor-1LPN7

I can't figure out what I'm doing wrong with the wiring. I connected the black and white wires from the motor to the black and white wires from a 14 gauge 3-wire plug (the motor doesn't have a ground wire, so I didn't connect the green wire from the plug to anything). When I plug the wire into the socket, the motor doesn't spin, it just vibrates a little and gets warm.

Do I need to get a capacitor? The motor instructions and specs make no mention of needing a capacitor, but I'm now reading on a lot of websites that you need a capacitor to run a single phase motor.

Also, this motor has a brake with two "C2 blue" wires. Any idea how to wire that?

Any advice would really be appreciated! Thanks.

How fast do you expect this motor's shaft to "spin"??

With a rating a 2RPM, it will take 30 seconds for ONE revolution of the shaft to complete.

Did you run it long enough for it turn at all?

kbsparky, thanks for the response. 2 RPMs happens to be the ideal speed for roasting pigs. I plugged it in and watched the shaft for about a minute and it didn't budge. So, it's not as if it was moving and I didn't see it. Is it possible that it takes some time to warm up or something?

You need to energize the brake coil to release it. If it's 120 volts, just parallel your power cord to the motor leads so both will be energized simultaneously.

Double check the installations diagram/instructions for the brake voltage. I would imagine they would be the same.

I like the idea of roasting a whole pig. We used to do that back home around Christmas. It looks like you only have to leads to connect? Is this correct? 2 RPM seems perfect. I can smell it now.
