not 100% sure what you’re asking. Are you talking about the starter capacitor??

A motor runs when the appropriate wires are connected to a source of electricity. There is usually a device called a switch to turn the motor on and off just like a light bulb has a switch to turn it on and off or ‘make it run’. So are you asking about a switch to allow the motor to be turned on and off or are you talking about the electricity which in fact is actually the source of power that ‘makes the motor run’?

a switch can be purchased just about anywhere. hardware store, home improvement store, even walmart. just make sure the current rating on the switch is equal to or greater than the motor.

ok thanks, so I buy the motor and the switch.

So when I get the motor just open the compartment where the wires are and connect to switch?

Usually you’ll use a 3-wire double-insulated cord. You wire the
3 wires to the motor on one end (follow wiring diagram on the
motor or look your motor model # up online for the diagram) and
a 3-prong plug on the other. Then you cut the cord in half
where you want your switch-box to be and you wire the 3
wires to the 3 poles on either side of the switch.

Some old switches only have two poles and the ground wire
bypasses the switch entirely.

If it is a 230v motor, you will need a two pole switch., look for a HORSEPOWER rating on the switch equal to or greater than your motor, if you go just by the amperage, your switch will have a very short life.

If you are using a 3wire cord on 230, I like to paint the white wire RED as a reminder that it is HOT. black would also work . . .

Loren said…”Some old switches only have two poles and the ground wire

there is a green screw on the switch that both ground wires go. the white wire is the one that bypasses the switch.

bottom line: if you don’t know about electricity a life is worth a heck of a lot more than an electrician, and i kinda get the idea you are not that familiar with it from your questions.

cheers

It would be nice to see on the motor page for grizzly to show all in one page that says you should get this switch and that switch if your homemaking a grinder or etccc.

Sorry joez no Insult intended but I had a good laugh just reading the Title Line before even coming here.

”I know where to buy motors but where do I get the unit that makes the motor run.”

I was going to say it’s called JUICE and it comes out of that Thingy on the wall with 4 Slots in it. 2 over the other 2. (Just Funnin’ joez)

So now you have the Motor and the Switch and Know about the Three wire, Wire. Now you need the Plug. I’d suggest a Three Wire Plug with One of the Plug in Prongs a Ground Prong. That Prong is Wider than the other one. It has to be Plugged into a “JUICER” with a Corresponding Wide & Narrow Slot.

Actually….. I have 2- 3/8” Drills. One has a Ground Plug with a Forward and Reverse Switch but No speed control. The other one has a Non Ground Plug (Both Prongs are the same size) and a Speed Control Switch but No Forward and Reverse Switch ( an older B&D) and it runs in the proper direction regardless of how I Plug it in. Someone told me it’s “Self Grounding” so I just said “Oh. I see.” I DON’T Really.
