motor so powerful it needs a motor to cool it?

@EZ4U2Say11 5 ай бұрын

All of my rc car motors have a separate fan motor to cool it i guess they are powerful too 😊

@waynec369 5 ай бұрын

Got nothing to do with it. Motors that run at lower than base speed, i.e. controlled with a VFD, the built-in fan can't provide adequate cooling. Therefore, an auxiliary blower is used. You can see this done on fractional HP motors all the way up to 1000 HP motors.

@rfreaky4717 4 ай бұрын

It's pretty normal for these types of motors as they can generate heat even when not turning so it cannot cool itself and need a separate motor for that.

It's indeed speed, and also if it's a synchroon motor. They usely run slow speeds and need separate cooling.

@pat8988 4 ай бұрын

From the looks of the motor interior, I’d say that the blower needs a filter.

This is what i call complete restoration..not just like you can see in many videos..aa all is fine just clean it new paint and done... Here it was done properly! Great job

Awesome stuff, it would be neat to see how you got the coils into the stator without messing up your insulation paper. Keep America working, thanks for sharing 🇺🇸

I am certified from Becker vacuum pump. I send my motors out when I see internal issues. What a art. I loved this video. Thank you. I simply change bearings and test amp loads before and after I rebuild, if there's ever a issue I'm forced to send them out. This is above my capabilities currently and I appreciate the video

This is really educational. I’m more on hightech side of the electrical spectrum. Never touch industrial gear, yet it’s the basis of everything. So it’s really nice to see it like this.

That looks a lot like the motor used on the big Cumberland B60 grandulator machine at a place i worked at. You did an awsome job rebuildiing it ❤

@zacharyl.5354 5 ай бұрын

Just stumbled on your page, very impressive looking work! Just wondering what the value proposition could possibly be on a rebuild like this versus ordering a new one? Seems like a ton of work 😬😬

@tomball3219 5 ай бұрын

Some motors have lead times of weeks or months which can lead to serious costs due to down time. Rewinds can be done in a matter of days avoiding those client additional business costs.

@connerlabs 5 ай бұрын

Well this is how they are made, the exact same thing happens in the motor factory when you order a new one! So the only scope for cost saving is if it happens in India instead of your local rewind shop. I doubt that is enough to offset the cost of the rotor, armature iron, and shipping.

@christopherleubner6633 5 ай бұрын

For a big one like this about a third to half the cost, but the real value is that you got a lot less downtime, a couple weeks vs months.

Really puts into perspective how cheap combustion engines are.

@dnomyarnostaw 4 ай бұрын

@nils1953 Not a fair comparison. To compete with the amount of work this motor has done, 2 years 18 hours per day continuous, you would need 4 or 5 15k Diesel engines, with all the maintenance they need, filters, oil, belts etc. If Ice engines were cheaper, they would be used instead. And don't forget, it took a flood to shut this one down.

@rkan2 4 ай бұрын

@@dnomyarnostaw Absolutely. For stationary applications it only makes sense to have combustion engines if there is no eletrical grid OR you don't have a reciprocating combustion engine OR it is a backup.

The rewinding seems pretty labour intensive. How is this more economical than replacing the unit with a new one? Assuming the same model can be sourced.

@WarmPudgy 4 ай бұрын

Aren't the stator laminations also lacquered? And by cooking it, you essentially turned the stator into a giant block and introduced eddy currents? Honest question, you rewind motors not me.
