Dimond ball cleaner RPM

[Nyquil]

The funny thing is, if I didn't design and build my ball polisher in order for you guys to copy, thereby eliminating the need for your own creativity, what other ball polisher would you be copying in order to build your own?

I already did the hard work, I didn't just sit around and wonder who's ball polisher I could copy, I INVENTED this ball polisher, made it real instead of just an idea!

What pisses me off, is that I don't even get the respect from people like you who copy my design in order to build your own!

Respect is saying something like, Hey, RKC, thank you for designing such a great ball polisher, you made it an extremely simple machine, and yet so effective. Would you mind if I copied your design and build my own personal ball polisher?

I'd just say sure, go ahead, knock yourself out, thanks for the compliment!!

But what I hear is I'm going to build my own ball polisher just like the Diamond ball polisher, because I think I can build it for about 50% of the cost of a new one, because I'm pretty good with my hands! And when I get done building it I'll post up the pictures of it on AZB so everyone can praise me for my accomplishment!!!

Well Glen I am just one guy on this big forum, but I love my diamond polisher. It's built like a damn tank and is really quiet. There is no better product on the market than the diamond polisher that is for sure. I have no doubt it will last me for years and years. This is one thing also I like about diamond they are putting out well sorted commercial-grade products for consumers and supporting American jobs in the process.

Thanks for making such a solid machine (that makes others want to replicate). I know you have provided a lot of esoteric insight over the years to diamond and all of us benefit from that from a player/product perspective.

Cheers
Brent

So what faults does the ball star polisher have compared to the diamond polisher?

I was gonna get the diamond one but found the ball star one abit cheaper on the shipping side so went that route.

I just finished an app using an AB PowerFlex 527 VFD that spun a 1.5hp motor at 1/3rd of the nameplate 1725rpm that moved a conveyor 5ft wide and ~50ft long, for continuous production run. The fan cooled motor has zero threat of burning out.

Nothing, if you don't mind the mess from the liquid cleaner solution. Can only clean 8 balls in that crock pot design, ball still spin in a centrifical circle, and don't believe the bs about cleaning in one direction, then shining in the opposite direction, the balls are still in the same track requardless of which direction the platter is spinning. And its noisy, and built in China.

Read the following, I've already mentioned thus before

Maybe that's because it's NOT an AC motor!!

An AB PowerFlex 527 VFD is a cip axis drive and is used to control 3ph AC motors.

Again, I had no clue what's used in treadmills. According to your digging, it looks like DC. That makes sense as I believe it's still the cheapest way to produce great low spd torque and speed control.

Where are you thinking this unit would play a role in a ball polisher??

I honestly wouldn't touch AB for any application. Let alone a ball polisher. The point was, I just recently drove a 1.5hp AC motor with a VFD at 1/3rd of nameplate (1725/3=575rpm) under waaaay more load than a ball polisher would present, and that application runs 24/7. The post was meant to debunk the notion that an AC motor ran at a comparable spd to a ball polisher would overheat.

Yes, there are overly cheap motors that would crap out. However it doesn't take much to get into something far more robust.

A VFD can make a motor run slower than rated speed, however a major point of consideration at low speed is cooling. A typical electric motor is cooled by a fan on its shaft; at low speed the fan moves less air and at some point the motor will over heat. This is generally not a problem with centrifugal loads such as fans, pumps, and blowers because the torque required by the load drops drastically with decreasing speed. In this case, the motor is doing less work, and there is less waste heat to dispose of.

A VFD can drive a motor faster than its nameplate speed, however, above the rated speed, the motor looses torque (twisting force). At higher speeds, less and less torque is possible. The maximum continuous power (speed times torque) is limited by the motor design, therefore a VFD cannot deliver more power than which the motor is thermally capable.

A VFD can also make a motor more efficient, but only at reduced load and/or reduced speed. A drive system will not use less power when the motor is running at rated speed and rated load. In fact, it uses slightly more due to the losses within the drive.

A VFD can make a motor reverse without the use of contactors, but it can’t make the reversal faster than the combination of the motor’s max torque and the load’s inertia allows.

A VFD can make a motor produce more than its rated torque but only briefly. The amount of time is limited by either the drive’s overload capacity or the motor’s thermal capacity. A drive cannot make a motor produce more than its maximum torque. Max torque or Stall Torque is generally not shown on the motor’s nameplate. The iron in the motor can only sustain a certain amount of magnetic flux density, even if iron is driven harder, the flux density will not go up. The amount of torque a motor creates at the flux limit is the most torque that can be achieved.

Did I accidentally go to the electrical engineering forum?

Good info, I'm glad it's being shared. There's so much stuff that marketing fluff, or repeated incorrectly by someone who has no germane knowledge, it's nice to see actual knowledge being shared.

And just out of curiosity, is that 1.5hp motor you're referring to, being powered by 110v, or 220-240v???

I love that RKC is like the bad guy in a Bond movie, who, once he has Bond tied to a chair over a trapdoor under which are a bunch of hungry sharks, can’t help but boast about the awesome details of his plan.

“You’re plan is nothing new, Gold-Elbow. You aren’t the first two-bit criminal to steal the launch codes, and you won’t be the last.”
“Oh really, Mr Bond? Did those other average criminals also plant an agent in the IT department to code a back door hack for the firewall and double ID security protocol??”

This thread started with people being dumb assholes who don’t understand the details of the Diamond ball polisher and are butt heads to boot for copying someone else’s design, and is now basically a DIY resource for building your own diamond ball polisher

Does anyone know a source for these without waiting 10 weeks?

But you're overlooking one vital part of your equation, load resistance. Spinning a fan only has a load resistance of the air its pushing, and how fast you want to push that air.

Its a whole different load resistance to mount a 3/4" x12" platter on the motor shaft, then create resistance to that platter from spinning freely, by placing 8 balls, or even 16 balls on the platter, with a wax cleaner solution on them, separate the balls creating even more friction by placing barriers to which the balls rub against, and even more friction if you're using a belt drive system, that if the belt is to tight, will alone stop the motor from starting up.

I have been an Automation specialist for 37 years. The drive can handle this load with out burning out the motor or harming the drive. The problem is cost of the drive and nothing else.

Glen I posted a single phase low 120v hp drive that will work.

You keep saying that, I guess you're just going to have to show me how that'll work

Problem is, Diamond can't build them fast enough, and two, no Diamond dealer can hang onto them long enough to have a stock inventory, as they sell out as soon as they get them.

I love the fact that no other ball polisher on this planet has such high demand worldwide as the Diamond ball polisher has, I must have done something right, because the price tag sure isn't holding back sales

I have roughly 25yrs in automation as well. That won't matter though...lol.

This application argument is a glowing example of the 'Dunning Kruger effect'.

Talk is cheap, lead by example! You already know my example, where's yours??

I'm sorry. Did you want examples of the automation equipment I've worked on for the last 25yrs that uses small hp VFD/motors, or an example of a pool ball polisher that I haven't made. If the latter is what you think motor application knowledge should be basd on, then industry is in big trouble. I'd wager an exceedingly extremely small percentage of automation specialists have diy pool ball polishers on their resumes.

Just simply pointing out that standing outside of the box giving advice is just moving your lips. When it comes to following through with your own advice is where the breakdown takes place. While you're sitting back giving your advice on something already working, mind you is not an improvement on what has already been designed, built, and in production. I unlike you, don't need to copy the Diamond ball polisher to come up with an new design that supercedes Diamonds current model design as even better, cheaper, and even more efficient. The only question I have to ask myself is do I need to
