Possible Cheap DC Motor

**Yoshi** · 07-20-2004 03:15 PM

Hello everyone!

I came across a site that has a cheap ($6) DC motor that may be similar to the Titan. Here's the writeup: 12v DC Motor

Igarashi Motor. 1.46" diameter x 2.5" long reversible DC motor. 0.125" diameter x 0.4" long shaft. 16 Vdc @ 300 mA (no-load rating). Solder-lug terminals.

Here's the website: http://www.siliconsolar.com/small_DC_motor.htm

Whadya think??? I don't have time to research this puppy so I'll leave it up to you.

**arceeguy** · 07-20-2004 05:43 PM

I doubt that it will work in an E-Maxx.

If it is only drawing .3 amps at 16 volts, it will have very little power. (It indicates high turns on the armature) You want to see over 1.2 amps @ 6V with no load (similar to the Titans) for it to be considered a suitable replacement.

Thanks for the link (we really do appreciate it), and happy motor hunting!

Look at the one beneath it

It is a MABUCHI 550!

**Bjorn** · 07-20-2004 07:04 PM

The mabuchi is 3-6v.... I wonder how many seconds it would last at 12-16v

**maxxboy** · 07-20-2004 07:29 PM

Not seconds, but minutes

**Yoshi** · 07-20-2004 07:43 PM

Hey, at least I'm trying.

Any motor we can find that's as good as the titans for less $ is a good motor. If it's even better than the titans, then that's a great motor!!!

**DodgeRam88** · 07-20-2004 08:12 PM

It would awesome if we could find this motor. It looks perfect for the E-Maxx

**ldimick** · 07-20-2004 08:13 PM

If this motor is a Mabuchi RS550-PF then IT WILL run at 12 volts. Check this PDF link out and you can see it was run at 12 volts.

I say - GOOD FIND!

Look at this one. It looks like the same one

OK, we all know where we can find drill motors - in cordless drills (and saws). But where else can we find them? Well, they're in my kid's PowerWheels Jeep by FisherPrice (the electric jeep that kids ride in). In fact, this thing uses two titans - yes, titans. I'm trying to see if I can order replacement motors for this jeep for less than the cost of titans - I'll let you know.

So, where else can we find good e-maxx motors??? Look around everything in your house, at the store, etc and try to discover a source of titans or better yet, big block motors (755's). If you can find something for short dollars then canablilize the motore, you win!!!

Happy hunting.......now I'm off to take apart the blender....

**maxxboy** · 07-20-2004 09:21 PM

My power drill has a johnson in it, but it prolly too expensive. Ill try to get price info. on it.

**E-Maxxer20** · 07-21-2004 10:54 AM

my dad has a craftsman 18v drill in the garage it has a big motor in it....

**maxxboy** · 07-21-2004 11:17 AM

Heres my power drillhttp://www.canadiantire.ca/assortmen...=1090426586823 its gopt a johnson(its in candaian dollars)

EDIT: this drill is on salehttp://www.canadiantire.ca/assortmen...=1090426691496 Its the same price as titans in my lhs.

**Bjorn** · 07-22-2004 10:53 PM

I'm pretty satisfied with Titans, at least until I can afford to go brushless.

I know Titans are made for Traxxas by mabuchi.
(model rs-550pc-8021)

But is there someone that could explain the difference between this mabuchi and the one labeled as a titan?

**maxxboy** · 07-22-2004 11:39 PM

I think it just capacitators, longer shaft and a titan sticker.

**wamason** · 07-23-2004 11:01 AM

Any opinions on this motor?

**maxxboy** · 07-23-2004 11:21 AM

That thing is HUGE im not sure if pinion shafts get that big though.

**DodgeRam88** · 07-23-2004 11:41 AM

wow it is huge

are the mounting holes the same, i'd buy that

**maxxboy** · 07-23-2004 11:47 AM

The problem is i dont think you can find pinions with a hole that big.

**wamason** · 07-23-2004 12:25 PM

If you had a drill press or a vise and a steady hand and some good bits, you might be able to drill out a pinion....."might"... But I've never tried it. I wonder if one of those motors would equal the performance of two Titans? And if it would fry the EVX...

**DodgeRam88** · 07-23-2004 12:59 PM

i was thinking that too, and i do have a drill press

**wamason** · 07-23-2004 02:00 PM

I have a big vise and a very steady hand :-) If I knew that the motor wouldn't fry the EVX--and give enough power, I would buy it in a heartbeat.....any ideas?

**70camaro** · 07-23-2004 02:58 PM

if i bought a 5mm pinon would it even be possible to drill it out to a 6.37 mm pinon without weakening the pinon. if so i just might do it. dont know if it would fry the evx but i would be willing to try it out.
and what if i put it on this batt. setup what do you think the motor would do.http://cgi.ebay.com/ws/eBayISAPI.dll...tem=5910227943

**E-Maxx Beaver** · 07-23-2004 03:20 PM

I dont know, it looks a wholw lot like the 550 emaxx motor

**70camaro** · 07-23-2004 06:56 PM

ok i just bought the 2 970 motors. they should be here in a little bit and i will let you guys now how they look. then i am gonna get started on the motor plate. yoshi any tips you can give me other then whats on your site.also the guy that is selling the 755's wrote back to me that you can buy them direct from him and he has tons of them so i will post were you can get them from in a little bit.

Ryan,

When working with aluminum, be careful. If you've not worked with it before it is unlike any other type of metal you're used to.

First, be very careful of aluminum dust - it is very flammable. In case you don't know it, aluminum dust and ground up rubber is used a solid rocket fuel.

Second, don't use a grinder (bench grinder, dremel, or otherwise). You'll be tempted to grind down the rough edges with a grinder. Don't. The aluminum will melt, get into the grinding material, and cause it to shatter. This will result in your injury.

Treat the aluminum more like wood than metal. I used a wood blade on my jig saw to cut it. Use a fine wood file to smooth down the edges. Aluminum will choke a metal file.

All in all, once you get used to it, aluminum is no harder to work with than steel. In many ways it is probably easier. However, what makes it easier (softer and lower melting point) also makes it more difficult (traditional metal working techniques don't work).

Good luck and I look forward to the data on the 755's.

Yoshi

**IDMadMaxx** · 07-24-2004 11:23 AM

would it work to turn down the shaft to 5mm for a portion of its length? Like a stepped-down section that would also act as a shoulder for the pinion? Or, would that create a stress area?
Puleeezzzzzz let us know where those motors are for sale at.

Click on that link and then go to other auctions.

**70camaro** · 07-24-2004 08:07 PM

thanks yoshi for the tips. and the motors that i bought are 970s also i was thinking of getting the batt. setup that i posted a couple of post back wonding what you guys think of that sett up or the price or do you think to slow maroon could build one for cheaper

**70camaro** · 07-27-2004 10:58 AM

i just got my motors in yesterday and these things are massive.they haft to be atleast twice the size of the titan.these things are so big that its gonna be tricky on getting them to mount up without hitting the trans.i will haft to puts some pics of it so you guys can see what im talking about. im just waiting on the metal to get here so i can start the motor plate. also what do you guys think of this cvd setup and if i bought this what would be good for the centers

**wamason** · 07-27-2004 11:43 AM

I'm curious to see if they'll murder your EVX :-) Hopefully not!

**70camaro** · 07-27-2004 11:52 AM

ya i hope that it wont fry the evx either but if it does start to get really hot.by taking off one of the motors would that help.if i did fry it what about this for a new one

Ryan

**wamason** · 07-27-2004 11:59 AM

Yea I noticed that ESC. I've never seen or heard of it before. Anyone else know anything about it?

**70camaro** · 07-27-2004 12:13 PM

the part with the heat sinks looks like someone possibly made it or something.so that it would be able to take 2 motors or be able to take 16.8 volts

Ryan

**970KING** · 07-27-2004 12:42 PM

You can get a pinion gear from https://sdp-si.com/eStore/ that has a 6.35 MM Shaft. I just order me two 16T 32 Pitch stainless steel. I paid about $20. her are some parts links that all have a 6.35 mm bore and set screw, they differ in Tooth material used.

**wamason** · 07-27-2004 01:08 PM

I just ordered 10 Johnson's from robotmarketplace.com :-) Roughly $50 shipped. Not to bad. Translates to $5/motor including shipping.

**70camaro** · 07-27-2004 01:12 PM

wow thanks for the links.if i am unsure about the amount of power and how hot everything is going to get what would be a good gear ratio to start with to make sure i dont get the batts evx and also the motors to hot since i only have 2 of them right now.

Ryan

**traxxasdude4964** · 07-27-2004 01:17 PM

i used to have an E-Maxx and i ran it on drill motors( the 750's) and i still have like 8 left that i am trying to get rid of. pm me and maby we could work out a deal.

**70camaro** · 07-27-2004 01:19 PM

well i am gonna try and get these 970's in for right now but i think there are some people on here that are looking for the motors you have.
