wireing 12 volt gearmotor
« on: December 05, 2007, 11:15:46 am »
 The gearmotor i got off ebay just has a black and red wire comeing out of it. As i previously posted i am going to use it to raise and lower the saw head, (my arm got really tired). What is the best way to wire this motor to reverse the current, keeping in mind cost and simplicity?,,,bedway

Tarp motor switch, call your local parts shop that sells auto and heavy truck/trailer parts.

It changes the current path without the messy relays.  Two wires to battery two to motor.  Worked on the one I built. I think it will handle up to 50 amps but should have a fuse or breaker installed just in case.
 

 

 

The knob is spring loaded and returns to center "off" position.  The knob shaft is threaded and will fit through a 1/8" piece of plate easily.

An other option would be a pair of push button starter switches, one for up and one for down.

It don't even need to be a knife switch.
A two pole switch is a few bucks at the store, less at a junkyard.
If you look a little bit, a self centering one can be found, think car window opening switch. :)
That's a double pole, double throw, self centering rocker switch if I'm thinking clearly.

Bedway - what kind of gearmotor did you get - what was the original application?  I'm thinking the same thing as you!  My shelby-type winch works great but it takes 20 turns to move the head one inch.  I was thinking along the lines of a 12v winch that you can power-in and power-out.  Not sure if it will hold the load in one position without creeping though.

Window switch is a DPDT but it usually only powers a realy that provides power to the motor.  They are not nearly HD engough to carry the current of the gear motor bedway is using.  Well, it will one time and then it will melt to your finger. :D
The tarp motor switch is about $30, how cheap do ya want?

Guess it depends on how big his motor is.
I use them all the time with no problem. :)

bedway temporarily connect the 2 wires to a battery.  Note the direction of rotation. then switch the 2 leads to the battery. If the motor reverses, the tarp switch should work fine. If it doesn't reverse when you switch the wires, the motor is a wound field (ie not permanent magnet) and it will require some internal modification to make it reverse.

Just get yourself a relay and run it off of the 12v supplied.  You could use as small of a switch as you want if you run a relay.  Very easy to wire.  Then the relay takes all of the current and the switch hardly ever fails.  Then you run the little switch and little wires into a sheathed cable right to a remote control (still attached of course).  Then you can have a small hand held remote that you can carry or set in a holder for easy operation. 

If you are not to familiar with relays read this once over.

There is a special contactor and rocker switch you can get from warn or super winch. It has the everything to reves the motor. May not be the most inexpensive system but works really well.
