3 Lead Reversing Motor

[calstar]

Got this from the scrap yard, need some info on the motor like how do I hook up a manual switch for it, what type of switch, etc. Unless it was on a fairly long run I don't get why it used #10 wire for only 4 amps. Why is there no ground wire, was it relying on the flex conduit for the ground? . All made in USA; had a short section of 1/4" stainless cable on the drum. Pretty nice unit; if possible I want to make some sort of shop lift with it.

thanks, Brian

14 AWG would be plenty large unless a very long run. 10AWG might have been the only wire he had available. You would need a single pole, double throw center of, momentary contact switch. Make sure the switch is rated for 120v and at least 6 amps. 10 amps would be better.

looks like it will be a very nice winch!

I don't understand, are there 2 hot wires coming in to the motor, red and black, white neutral? No ground; or conduits the ground path? And both throws are momentary?

Thanks, Brian

you will make L1 your neutral connection @ Motor terminal 4
L2 will go to the common (center) terminal of the SPDT switch
the #1 motor terminal gets a wire from one side of the SPDT switch
the #2 motor terminal will get a wire from the other side of the SPDT switch
when you throw the switch either way you'll be completing the motor circuit in it's respective bias,
the neutral has already been supplied and is not switched in this scenario.

Previous owner used either the mounting metal for ground or the greenfield. Greenfield with proper connectors is usually NEC compliant for grounding under 20 amps. Some cheap greenfield isn't listed as a grounding conductor.

Let's complicate matters!The power from the control switch will have to go through the proper limit switch before the motor connection. To test, carefully run the motor so that the switch activator is near the center of the lead screw. Run the motor and manually trip the switch the activator is moving toward. If the motor stops you have it wired correctly. If it doesn't stop you'll need to reverse the wires to the switches.

I should have clearly stated I do not want to use the rotary limit switch, just one switch for direct manual control.

No ground; or conduits the ground path?

As stated above, some jurisdictions allow flexible metallic conduit to act as a ground conductor, but there is a green ground screw provided on your motor electrical box for a ground conductor.

thanks, didn't even notice that Brian
