110V dc electric motor with 4 wires

[jurilica]

So to confirm how to connect motor to power supply like on picture.
( + ) 1 and ( - ) 4 to power supply
2 and 3 connect with wire

- to change direction of rotation of motor switch 1 and 4

 

[Les Jones]

You have it correct for one direction.
( + ) 1 and ( - ) 4 to power supply. 2 and 3 connect with wire. (It does not matter which is positive and which is negative.)

Edit. When I first posted I made an error. This should now be correct.
For rotation in the other direction link 3 & 4. Apply power to 1 & 2

You should only need to swap one pair, either the armature or the field.

I want to test to see in wich direction motor is rotating from post #21 if is not rotating how I want then I will connect to other position 1-2 to power supply and 3-4 connect with wire

 

[MaxHeadRoom78]

Use #23 connection and find out which way you want it to turn, if uni-directional application.
