I also go to great lengths and cost to get a drop in Brushless Motor to fix these motor and controller problems once and for all, only to fail miserably. Score: F-

What a coincidence! I have a very similar Kitchen-Table-Pressy-Pressy-1000™️ . Great job. I just can't stand bad quality products like this. We'll be installing one in our camper too, and we're happy to pay the price for quality, but surely they could have gone a little bit further with the quality on this one. Especially the corrosion on the PCB. So big thanks for this. It'll save us some head scratching in the future. 😎👍🏻👍🏻

I was able to chat with the folks that make the Maxaire fan today at Overland Expo West, he said that they have a deal to provide their fan rebranded for Ford, but Ford said they needed to make the motor brushless, so now we know what it takes for them to make improvements. It will be a Ford-only exclusive offering for some time, but the motor will be the same form factorwith an -IF suffix. He said it should be available thru Ford parts. Soon.

As I plan my campulance build, I was astounded by the high cost of these fans and their poor apparent quality. And they're the best on the market! This - along with wanting to cover entire roof with solar, and only admitting filtered air - has set me down the path of designing a contained, ducted HVAC system around EBM-Pabst electronically commutated centifugal fans, which have the additional benefit of internal speed control via PWM input (and available in 24V to match my electrical system). Kudos on your first-rate MacGyvering!

Bro!! My bearded savi bro !!! I fixed my Fan because of you !!!! Thank you for making me a better man and a better handyman today !!! We need more angels like you in the world. 🙏🏽👏🏽 All I did was take it apart clean it by hand and with the sham wham. And whammm smooth as original. It was driving me nuts when I didn’t have the music on. And was about to just throw oil inside its main shaft. That’s the ignorant me. But a little less ignorant because of you. Now I wonder if the main belt in my diesel transit is having not a bearing sound as I thought but a wear and powder inside the alternator. Cause it’s kind of the same thing but at it’s own annoying frequency. Well see. Thank you again 🙏🏽

A good brush bedding technique is to tape a strip of abrasive tape to the commutator (abrasive facing out) and reassemble the motor. Use a drill or similar to spin the rotor slowly and the abrasive tape will make the brushes conform to the diameter of the new commutator. It won't take long so keep checking progress and when done strip motor and clean out any carbon debris. Don't forget to remove abrasive tape!!

This was so helpful, thank you! I only ended up cleaning out my motor and using a little WD-40 on the bearings as I’m on the road with limited tools and supplies. Hoping to swap out the bearings, polish my commutator and maybe shape the brushes a bit (they don’t seem to sit nicely against the commutator). There really has to be a brushless solution out there!

@Everlanders 18 күн бұрын

In this case I'd consider the WD-40 to be a solvent to clean the grease out of the bearings... Consider regreasing them by putting them both on the long end of the motor shaft, about 1/2 inch apart and then roll a piece of masking tape 90% around the outer surface. Then fill the void in the middle with some thick grease and wrap all the way around with more tape... Then push the two bearings together, this will force the grease through the bearings and it will come out both sides. Remove all the tape and wipe them down with a paper towel and reinstall... I haven't had to touch mine since doing that.

To anyone considering changing their brushes using this tutorial, do it! The only addition I would add is be careful when changing out your transformer. The metal leads are rather frail so you’ll have to be gentle with them. Otherwise, just make sure you keep track of where everything was located so (take a pic) when you re-solder everything and screw everything back together, you’ll know exactly where to put everything back.

100% agree! We had to replace the circuit board AND the fan motor after they fried after only 2 years of use. First the PCB went out, got a new one, and then the motor went out, got a new one. We said no more and bought a DC to DC regulator to keep it at exactly 12v.

They used similar motors for heaters in 1960’s to early 2000 heavy duty trucks, buses etc. If memory serves me correctly the differences in motors were largely shaft length and mounting screws. probably could find motor guts in a wrecking yard, if not a motor that would fit. Most of the Peterbilts, Kenworths, Freightliners of that era used Red dot brand heaters. Hopefully the supply chain will catch up soon.

one thing I would have to suspect is the diameter of the brushless motor, going larger and lower power provides a smoother but weaker motor. This would make the motor more quiet.

I may look into winding a 3d printed prototype in the near future.

Couple thoughts come to mind. Would a 12volt, 12” automotive radiator fan fit or a 12” computer case fan?

@Everlanders 2 жыл бұрын

Great Ideas, most electric radiator fans I found pulled 20 or 30 amps which seemed overkill, the PC case fan was a winner however, I installed this one: kzfaq.info/get/bejne/fseYa5xy0pasqY0.html

@Everlanders 2 жыл бұрын

Much the same as a brushed motor, except the motor has no brushes and the magnets spin and the windings are stationary. Additionally, there is an external speed controller that pulses the windings in series. The timing of these pulses is calculated based on the magnets passing the unused coil, this would be a sensorless motor, or a sensored motor would have hall effect sensors imbedded in the motor which the controller then uses to time the motor.

how is your hot water diversion working?

@Everlanders 2 жыл бұрын

Perfect! I've since added additional logic to heat the water just a bit in the morning, and as the batteries get nearer to full, the temperature setpoint keeps increasing to a maximum of 80°c. Then it turns off when the sun goes down and it's still plenty warm till morning 🌄 I've also tied our 2 air systems to this logic, so as the batteries approach 95% the air compressors fill our air tanks for water pressure and pneumatics with excess solar...

@@Everlanders Very cool! I ended up with a robust looking radiator fan that was flat. The computer fans are 10,000 hour motors as well. I'm sure it will work out very well for quite a time. I think your major concern will be keeping dust from piling up on it, because it is lighter. It's a catch 22 though, because if you add a dust filter, you HAVE to change it regularly or you're choking off the motor. :P The world needs a self dusting motor. :D
