Need advice to get an electric motor to rotate clockwise or counter clockwise

I recently purchased a Molon #EMR-63-1 electric motor for a whirlpool chiller project I am working on and need some help getting the motor to consistently start CW or CCW.

I want to try cooling one batch with the wort spinning CW, and another spinning CCW to see if the wort will cool quicker either direction.

I wired the motor to reclaimed power cord...red to black, white to white, green to green and the blue (on the motor) not used. It runs just fine but starts in different directions. The motor was also shipped with two start capacitors. I pretty much have no experience with this, so I was wondering if someone could help me with what I need to do to get the motor to consistently start either CW or CCW?

Below is a link to the motor. I can also provide photos or try to answer any question you have that would help you help me.

Thank you in advance!

The answer is in your link: It is a counter clockwise motor not a reversible motor. It might be possible to disassemble it and change internal connections but the practical solution is to return it and buy a reversible motor.

 

Welcome to the forums.

Since I can't find any wiring info on that motor we need to experiment with wiring. Do you have a small fuse and fuseholder..... maybe 5-10 amps. Something we could temporarily put in the hot line to protect the motor.

I don't know why that motor came with two capacitors. Are they both the same values ?
I'm actually surprised that they shipped it with the caps and no wiring info. Is there a little diagram on the motor.

Here what to try at first.
Leave white and green as connected.

 

Then why does it start CW one time and then CCW another time when I plug it in? How do I get it to start CCW every time? Because the cooling water flows through my immersion chiller CW, so I think the wort moving CCW via the motor and stirrer would work best anyway.

 

Thanks for the welcome!

I don't have a fuse or fuse holder. I'm just getting started with this project but can get something tomorrow. The caps are the same value. There is a wiring diagram on the side of the motor. I don't have much experience with electric motors so I wanted to come here to get some advice and direction.

I understand the diagrams you sent me and will try them tomorrow and report my findings.

Thanks!

 

You've got a lonesome wiring diagram on the side of that motor ?

Care to share ? Shoot a close up pic and post it here.

 

PJ, I'm not sure what you're trying to convey with that diagram, because it is not technically correct and is not accurately labeled. Motors of this type do not have "neutral" and "hot" connections and in the diagram, it is more concise to draw the capacitor between two motor leads... whichever two would put it in series with the start winding.

I'm not sure why this thread was even started as the motor information states that it is CCW only... this cannot be changed. Please do show us the wiring diagram provided on the motor. A white, blue and red wire is not typical for a capacitor start motor.

 

Here is a picture of the diagram on the side of the motor. I was having a hard time getting a clear image of the diagram with my camera. Let me know if you need me to be more specific about something that is not clear in the photo.

 

Looks clean and clear to me.
