Default Where can I get a faulhaber 3557k012cr motor?

Anyone know where in US i can get a faulhaber 3557k012cr motor? I checked on ebay and I haven't found one with a CR suffix series and 12 volt. And plus everything on ebay comes with a gearhead attached to the motor.
This will go on a wedico Cat740 unless someone recommends a different motor to replace the stock Buhler motor? Looking for a little more power out of it. Thanks

It needs to end with 12CR.
There are 3 variations.
C = weaker than original buhler motor
CS = slightly stronger than buhler
CR = much stronger than buhler.

Also 12 for 12 volts. Alot of them on ebay are 24cr for 24 volts.

Thanks though for the search.

the Faulhabers are great motors, especially where on need much power in a compact unit. The 3557 is a pretty pricey engine, and possible quite overkill when it comes to power on a 740) Can recommend to test the Servonaut TM120 motor, strong and a good price. (The one with a gearbox is called GM32U450) Use them with Tamiya trucks with semi tippers, twice the weigth of a 740 I would suppose, gets the job done. I'm not familiar with what motors are in the 740 originally, but have heard several complained about the power. Some even throw out the 3 speed, and put a 1 step planetary gearmotor.

Here is a hobby dealer in Germany that have the Faulhabers, possible a bit better price than the industrial dealers, that likely also are in the US

(the Faulhaber motors does not have the same 'engine brake' power as standard DC motors, more feels like turning a brushless motor, even they are not brushless)

Will the servonaut s20 speed control be able to apply brakes? Or will the truck roll on it's own if it's on a hill?

The S20 is suitable also with braking Faulhaber motors/ 'coreless motors'

Default Re: Where can I get a faulhaber 3557k012cr motor?

So I just bought a faulhaber 3557k006c (6 volt) version and I confirmed with faulhaber that I can run it on 12v but I would need to lower the speed since it will be running twice the speed with 12v. So I'm thinking if I limit my esc thru my radio and somewhat match the drive speed with the original buhler motor, do you guys think it will work out? I mean the motor I bought was $15 shipped so if it fries, I'm not too worried. Any thoughts?

Yeah, limit the ESC top speed through the radio. Congrats, quite an investment I can guess, an top of the line engine) Buy the way, the question needs to come, was the 12v version not avaiable?

Thanks for the tip!!
I was not able to find any 12v version without a gearbox attached on ebay. I did not want to spend $400 for a new 12v CR version which is the one that I really need. I found the 6v C version for $15 shipped so I thought to myself as long as it does not harm the speed control, I'm ok if the motor burns out at $15.

Small update. I ended up getting a 6volt version for the faulhaber 3557k006c.
I'm going to limit the speed thru my radio so I wont over spin the motor since I'm using a 3s lipo. I sorta explain in the video. I'll have to test with actual load to see if it's any better from the original motor.
