You mean the bow-thrusters? I think the larger ones are hydraulic motors, but I'm pretty sure the smaller ones are likely electric.

No, it really isn't. Lots and lots of these motors are made, because the vast majority of them are used for pumping well water. The motor you see in the pic is sort of a "glorified" version of a well motor, with special bearings, etc. Because they manufacture these in such vast quantities, it helps keep the cost down.

And as we all know, we all have to get our water from a well of sorts, -somewhere.....

Daniel, known here as Dafni, can tell you some things about the future when it comes to energy delivering sources. (think in terms of fuel cells)

Only 7 posts young, and i like him already..... :p

I quite agree Jato Killer. One thing I have always wondered with the brushless motors we use in our rc's is that they really can't be that expensive to manufacture. Brushed motors have far more moving and fiddly parts to manufacture and assemble than brushless motors. Surely, with the higher demands that I'm sure will come in the future, the manufacturing costs of brushless motors will dramatically decrease.

Nope..

a friend of mine is chief engineer on a large passenger ship (280 meters long)
every motor that drives the ship (named Pods) works on electricity. those things are H U G E! the big Diesels and Gasturbine are used as energy generators..

a few megawatts..

Thanks for the kind words! -I'm just a realist. It really irritates me when someone won't look ahead and "get on board" with some of this stuff. Instead, they would rather live in a cacoon somewhere. I agree, not ALL new technology is great. My Mom just bought a computerized dishwasher that does everything but wipe your......

-At any rate, it would be great, except it has been through three circuit boards in a months time, the parts are on backorder, etc. etc. This is a brand new piece of equipment that is less than two months old, -and it's a POS. Some "new technology" stuff is just plain uncalled for. However, some of it is also very cool.

In regards to the fuel cell thing, -yes, I've been reading about it. That is truly something that could make batteries obsolete.

I can hardly wait!

Exactly. Look at how inexpensive you can find CDRom motors and fan motors. They crank those things out by the tens of thousands.

Admittedly, comparing a CDRom motor to a Lehner isn't a fair comparison, especially considering the magnets used, the windings in the stator, etc.

The motors we are playing with are very much a hybrid in terms of construction.

I have another brushless motor here in the shop I've been playing with. I'll post a picture of the motor and controller in a post or two. I'm at work right now and gotta get busy before I get busted!!

It's small, -5 amps at 110V. This sucker has some pretty serious torque. I tried to hold it with my hand and roll the speed control up, -that was a mistake!! OUCH!!!

I'll get back with you guys in a bit.

To an earlier post: Why would anyone grumble about BL motors? They are superior in just about every way (except maybe for cost) to brushed motors.

As far as new BL technology, I can see maybe better magnets, and better starting (low speed) control. I really think battery technology (or some type of fuel cell) is what is going to get better by leaps and bounds. I too like new technology and am usually willing to give it a try, just gotta watch out for those stupid "computerized dishwasher" type things. I like my manual dishwasher just fine - one of the kids. :) Just gotta apply new technology where it makes sense, not just for the sake of having it.

Oh, I've ran into several older guys who were so stubborn that they insisted their original RC-10 running a 15 turn motor was just the way it was meant to be. I had one older guy make the comment, -"man, you can't even control that thing at 50 mph, -what's the point?" People with that type of attitude will never be convinced, -they simply won't allow it. As to your comment about BL being far superior, -those of us that have gone BL, -well, let's just say that we'll NEVER go back!!

I agree 100%

That is a good size motor. I think in a small car or so it would be pretty cool.

Ok, here's one of those smaller units I was talking about. These are basically brushless stepper motors that are driven off of a brushless controller that is slaved to either a PC, or a PLC.

This one is one of the smallest one's we get to work with. These motors also act as positioning devices for manufacturing, etc. and are used for indexing stuff for robotics, etc. They replace complex mechanical positioning devices of yesteryear.

Here is one of the larger ones we work with. This is the one that almost wrenched my hand off!! After reading the 2HP rating on the nameplate afterwards, I really felt like an idiot!!

Attachment 1077


Here is the LVD-5 brushless controller. This unit is one of the smaller ones made. It is rated at 5 amps continuous at 110 volts. This unit can be controlled remotely via a PC realtime, -or even operate off of a PLC remotely.

mmm gocart :017:

Mmmmm dual BL gocart!:027:

Jato Killer, what engine is that in your avatar?

I would guess a 572 cubic in big block chevy. I think they put out about 650 hp out of the crate. Depends on the options you get.

Could you get me a couple of 100 hp models for my real truck?:005: :027: :018: Just kidding, but the way gas is going up up I'm considering it.
