Reversing Grain Mill Motor

[kj9tonne]

I have searched and searched for existing answers on this topic and I cant find exactly what I need and requesting help

I have a 1 HP Leeson Motor (with 10:1) Gear reducer and MM3 2.0. I also purchased a DPDT switch thinking this was going to be easy.

Can someone help me with a simple diagram showing hot, neutral Line wires and the motor wiring to the DPDT-CO switch? Any help would be greatly appreciated. I am able to manually switch the T5 and T8 wires without the switch to get both CW and CCW rotations. I just cant figure out how to do this with the switch I purchased.

Thanks in advance for any help or guidance. Brewing in the morning but doing so with hardwired for CW rotation and hardwired to extension cord

Thanks for the quick reply Bobby.

So center tabs are hot and neutral from power and tabs to the left in picture are T5 and T8? I am still confused what to do with the other L2 and Join leads.

Is your switch in the picture Center off ?

Thanks for the patience with me on this one.

fyi... love all the stuff I purchased from BrewHardware!!

The example Bobby posted provides the rotation switching capability that you requested.

You didn't indicate the model number of the motor, however, the linked diagram indicates that it is likely of the split-phase, capacitor start, type, if the component between T5 and T6 are a capacitor and a centrifugal switch. Otherwise, it could be a PSC, permanent split capacitor motor.

Regardless, I believe it's necessary to remove voltage from the run windings prior to inverting the start winding (T2/T8) and restarting in the opposite direction. You will therefore, also need to switch the motor on and off with a separate switch.

How about this:

Thank you for this. You even answered the question I did not ask about a separate switch for power. I think I proved to myself I didn't understand how this worked until I saw this diagram.

One final question - with the diagram above, with 110V energized, will I have an issue with the DPDT-CO switch in the center off position? I just want to make sure it is OK if the mill is running to put that switch in the Center Off position with power on, let the motor stop, and then reverse the direction by changing the switch.

Sorry about the last post. For some reason all I saw was the first line and not the remainder of the detail. Thanks again for the information.

Update - all wired with reversing switch and double pole for power and working great. Thanks Raouliii and Bobby M for your help on this! Very much appreciated.
