Kimble Electric motor

Greetings folks,
Does anyone have a 110/220 Kimble motor wired for 110 that has the specs plate? I’m wanting to convert it to 110 from 220 and can’t find an electrician that can figure it out. Looks like to me with my limited knowledge that you have a 50/50 chance of getting it right. All wires are black in the the motor. The 2 wires that are hot are still connected and the principal is that the controller just slows the motor by reversing the polarity. If the stop isn’t in place and you go too far on the controller it just reverses the direction.

Most Kimble variable speed motors have 4 wires and allow for low (110) and high (220) volt connection.

For low voltage:
Wires 1 and 2 connect to Line 1
Wires 3 and 4 connect to Line 2

For High Voltage:
Wire 1 connects to Line 1
Wires 2 and 3 are connected to one another
Wire 4 connects to Line 2

Be aware that these old motors are ungrounded and can be potential hazards.

Hope this helps,

Thank you for the help on this.

The old motors are only ungrounded if you don’t connect a ground wire :).

(If it only has a two wire cord, replace that with a new three wire cord.)

If you all get the figured out, please let me know what you find please.
I was wondering if one could trace the wiring in the motor by checking for conductivity.
I am also trying to figure out the best lubrication for this motor.

The best oil for electric motors, in my opinion, is turbine grade oil. It is sold for this purpose by motor shops and supply houses in small 4 ounce plastic bottles with a long spout, which makes it easy to apply. Here is an example:
