Hello,

I bought an old Orbit DP (I have read they were sold by JET). This is your typical Taiwanese DP and there are several versions of it, but they are all more or less similar.
This is the first time I venture to restore a DP, but I had fun doing it…. until I got to the motor.

The DP was operational when I bought it, no humming, no smoke.
I changed all ball bearings in the DP, so I was tempted and took apart the motor to change the ball bearings and violated the old adage “if ain’t broke, don’t fix it”

Long story short, after putting everything together the motor would come up, but soon started humming and smelled funny. After inspection, I see some burnt wires in the windings and it doesn’t start anymore.

The DP is excellent and after restoration and a new chuck, it has virtually no runout so I want to keep it regardless of the issue with the motor (that was the plan in the first place anyway)

I’m reaching out to you guys, for some advice in regards to my alternatives.
Given the prices I see online for new 1/2 motors I suspect buying new is preferred.

These are the details from the motor – pictures attached.
  • 1/2 HP
  • Singe phase
  • 4 Poles
  • 110V / 220V
  • I can’t read the RPM data
  • I can’t read the AMP

Questions
  • Is there a path to repair here or it is not cost-effective?
  • What are the parameters I need to look for when it comes to buying a replacement?

Any advice or general wisdom you want to share? (yeah, you can repeat the part I learned already :) )

Thank you in advance!
R.

Any recommendations?
I’m looking at the Grizzly replacement and other options at Grainger but I was wondering if there is anything I might be missing when looking at replacements.

Thanks!

Not too much to go wrong since it is simply mounted. Basically confirm the shafts are the same diameter and if the offset of the mount plate is the same.

How about buying the DVR motor and controller from Rikon?

Other than that, just a generic Dayton. Known middle of the road quality. Who knows what you buy from Griz or others.

I’m your occasional homeowner, occasional DIY… This DP is going to see occasional use, I’m sure whatever I throw at it is going to be fine and I would be able to pass this to my son :)

Where would you get a dayton? Grainger?

Also, should I use this opportunity to go up in power (say something like 3/4 HP) while maintaining the RPM? Or you wouldn’t venture on this territory and would rather keep the factory specs?
I upgraded the chuck from 1/2 to 5/8.

The rpm is most likely 1750, or thereabouts. Since the motor installs vertically, I wonder if it has. or needs a thrust bearing?
