I would like to use this for balancing Compressor wheels for turbochargers, but I see the motor is connected directly to the shaft for this item. Is there an easy setup that can make that the motor doesn't have to be reconnected to the shaft every time a new compressor wheel needs to be balanced?
Hi, an alternate approach is to turn the wheel with compressed air. We have tried it and works fine. Just make sure that the wheel spins at constant RPM for balancing.
@@dynexhobby Would you need to install something into the airline to secure the constant RPM? I'm also interested in this setup with the air compressor integrated for power.
I,m not using a motor drive to speed up but compressed air , is this also possible as air will possible induce vibration ? or can I take the measurement right after when i,m reaching my target RPM?
That is fine, I have used compressed air as well. The software will filter out frequencies above and below the test RPM or 1X as we call it. However, if the shaft is misaligned or bent or has slippage then that might be added to the imbalance signal as these discrepancies occur between 0.5X to 2X which is close to your test RPM.
@@dynexhobby I have a grinding spindle I need to balance. It's service speed id 40,000RPM. Do you think I could balance that at 5000RPM with your tool?
can this balancer be used to balance an RC Jet engine? the engine is basically like your setup here, except it, can't be spun with a belt I'll have to use compressed air.
@@dynexhobby ok that makes sense. Your design is really elegant! I presume the bar linkage system allows translation primarily in one axis, aside from some slight arctuate motion? What does this accomplish? I was considering a similar system, only I would allow for motion in two axes using a flexure bearing.
I watched this whole video hoping you would show how to identify a precise angle for weight placement. such as suppose the software says put a weight at 243 degrees. other than eyeballing how do you identify location. Second thing I was hoping to see is how far out to place the mass. It appears the answer is "all the way to the edge". So annoying to have you go into detail about the math coefficients and not show the measure placement of the weights. The other question I had was why you identified the inner part of the dumbbells as plane 1 and plane2. Maybe because that is where you knew weights would go. If I had specified the distances in the software to the outer surfaces could I have placed weights on the extreme front and back as well?
Software has been updated to deal with the type of rotor arrangements since this video. The software will show you where to place weights and also how far out the masses are after each run.
@@dynexhobbyalso if plane 1 says add weight at for example at 92 deg. That’s perfectly reasonable. The issue is when doing plane 2. If I says like 234 deg, is that from front view or rear view? That’s confusing because from the front, 234 deg would be well at 234. But if you look from the back 234 deg would be opposite side.
I am so glad I found your channel. I was about to develop something for my own purpose :)
Glad you like it. Our products have been 8 years in the making. More to come this year.
Thanks alot Mark, Laser setup keeps me busy but getting there.

Hi Larry. The Mark 20 and Mark 10 use the same air bearing shaft ? Where did you buy your speed sensor detector ?
Muito bom mesmo obrigado pó as esplicações
I want to buy it, it could be delivered to China?

@@lissettelopez8331 we normally use a large compressor with regulator. That generally works well for test as the compressor recharges.
I want to purchase this setup possibly X2
Awesome ❤️❤️❤️❤️
Are these one piezo sensors ? If not would it be possible with piezo sensors ?
Yes we have high quality piezoelectric accelerometers available that plug into Impulse 2. Please visit our web store.
Thanks for this fast answer ill visit your store...
Is this laser method much more better to "accurately" balance or strobing with a light can provide the same level of "accuracy" of balancing?
laser method is much better as it can provide more accurate locations for imbalance. Strobes can sometimes be misleading if not calibrated correctly.
Sorry, omit that question.
The great Mark . dear can you provide us this software , interface and sensors plz
Of course! Plenty in stock. Please visit our web store at www.dynexhobby.com

What is the maximum speed you can balance for?
So far we haven’t found a limit as we normally balance between 2000-5000RPM. Can go as low as 500RPM using specific software settings.

@@car9167 it’s possible but proceed with caution as this can be a dangerous exercise due to the heavy rotor speeds.

Good question, I'm not 100% sure because the micro turbine balancing uses the magnet for RPM and positioning
Hey bro can you provide this product for large size of blower impeller balancing
The system is scalable.
Calibration is compulsory for every time's ??
Calibration is required first time you setup a particular rotor. However it’s common to recalibrate if balance solution appears to drift.
Nice setup! What is the name of the optical module? Is it just for an index pulse?
Laser sensor module. It’s for indexing so balance weights can be positioned correctly onto the rotor.

@@weirdsciencetv4999 yes that’s correct
Can the system be set to calculate for reducing mass instead?
You mean remove weight? Yes, there is an option for that.

Hi you can order online at www.dynexhobby.com we can provide advice what setup would suit your requirements
Which dc motor You using for spin the shaft?
Its a small brushless inrunner motor from Hobbyking. A 370 size motor.
hey mate do you guys deliver to New Zealand?
Yep we sure do. In fact most of our deliveries are global.
Really good one. Shall I use this balancer for the motor rotor? What is the minimum balancing weight in grams?
Aravinth Kumar can be used for any rotor. The system can detect small weights much less than a gram.
Can you deliver in India?
Yes we deliver world wide
