I have a Dayton motor ac/dc series. model 2m172. 1/15 hp 5000 rpm, 115v ac/dc 25-60 Hz. It's revisable with 4 wires red, blue, black, yellow. If anyone can provide a wire sch it would be a big help. Thanks very much. art

 

The Dayton 2M range include Universal motors, which would make sense,
Test the resistance and identify if there are two windings, if so it is most likely the field and the armature of a Universal motor.
Which would mean that the two pairs would be in series, and reversing one pair will reverse the motor.

 

Motors usually have a name plate with information on it. Even some appliance motors. But as it is a Dayton motor it really should have a name plate telling us at least the volts and the amps. Often there is at least some other information.
Now for a question to the TS: Do you have a meter that can measure resistance? Either a VOM (Volts Ohms Meter)or a DMM, (Digital Multi Meter)??? Given that if it is an AC/DC motor it must be a universal type that has brushes and a commutator.
When we have the resistance measurement information along with the wire colors it will be simple to correctly provide the correct connection information. Until then there are only guesses.
AND I see that the TS did not even mention the motor voltage, which matters a bit.

He stated AC/DC 115v which puts it in the Universal category !
Reversible type, hence the four leads.

OK, then the TS still needs to identify the two circuits, field and armature, as to colors of each. That is most simply done by measuring resistance. As I already suggested. The alternatives might be visiting the Dayton website or finding a copy of the Dayton color code .

Why? If they're in series then the motor will spin. If you swap two wires, be it stator or rotor the motor will spin in the other direction.

If the TS puts the rotor together or the stator windings together then nothing will happen. But it's kind of hard to get wrong.

I already suggested it in the 2nd post ?!!!

" then nothing will happen"... Oh yes it will ! It will be a very low resistance shunt wound motor and will run but overheat (fry) drastically on 120v or 240v

 

Applying power to only one part, armature or field, will result in heating far beyond the safe temperature.

Yup! Tried that. Discovered exactly that.

 

Per the Dayton 2M series catalogue, they show all consisting of Universal AC/DC motors!

 

The wire colour code has been obtained from the name plate of a similar Dayton motor.



The armature leads are black and blue and the field red and yellow.

The black and blue leads are to be interchanged to reverse the direction of rotation of the motor.



Nandu.

 

This is what I had in mind when I said nothing would happen:

 

Certainly that is correct!! But that is only two of the possible combinations.
I suggested not doing a random connection because there are two possibilities that would probably cause damage by burning up the armature.
