Topic: New motor ready for beta testing

Hi guys,

I have a new main gear motor ready for beta testing. If you'd like to participate, use code "BetaMotor" to get it for 50% off:

http://www.filastruder.com/products/gearmotor

Be sure to select  "New Beta Version" before ordering.

Benefits over standard motor:

Square driveshaft - no more shaft/dowel pin
66% more RPM
120% more torque

I will note that it is loud, at least so far. It should quiet down as time goes on and the gears wear in. It also pulls enough current to overwhelm the power supply that comes with the Filastruder, so you'll need a 12v source capable of 3A continuous, 10A peak.

Otherwise, it is a drop in replacement, and has a square drive shaft for slip-free extruding!

Re: New motor ready for beta testing

Got your order. Note that this motor is much more powerful, so you might want to start off with 9 volts and see how the enclosure handles it, if you're still using it.

In.  Added an E3D cuz I think I borked my stock Robo3D one (plus I want to play with the nylon I made!).

Re: New motor ready for beta testing

I'm in.  Order placed.  Can't wait to experiment.

If it's worth doing, get a proffessional, if it's worth doing right, get me.

Re: New motor ready for beta testing

so I could post this:
On the pricey side, but this looks like a replacement for the power supply that could handle the new motor (it might cut out if you stall and are heating it though...):

Re: New motor ready for beta testing

If peak current is the problem but not really continuous, and if you have junk lying around,  you can consider running a small SLA battery in parallel with the 12v output.  I dont remember the specs on the stock PSU off the top of my head.

Personally I have a few 12V 50A power supplies lying around because I purchased 5 server power supplies off ebay for $50 and converted them. If you're a hobbyist it can be worth it to prep a batch of those sometime.

I love meanwell, but that jameco link is not a very good price. You can get 300/350W meanwells genuine on ebay for $60ish and clones for $40.

Re: New motor ready for beta testing

Man, I have to say, 28 Nm is a little terrifying. Even my 13 Nm motor was bending the 2x4 I put everything on. I'm currently designing a controller that would sense the current on the motor, possibly implementing PID to provide constant current / torque and variable speed via PWM. This would provide a safety buffer in case it stalled, although I'm pretty sure stalling that motor would probably just destroy everything smile

I think it would too, which is why it is in beta and recommended for advanced users only.

Yeah.  The only reason I kindof liked it was that it was enclosed.
I ended up getting this one from Amazon b/c I'm a cheapskate:

Re: New motor ready for beta testing

Arrived today (Georgia)... what's the metal sleeve on the motor supposed to do other than block the cooling fan?
I'm going to (try to) power it with a 350W ATX power supply until the new one from Amazon arrives...

I also have a 10A 12V meter (I think it came from Harbor Freight) -- it's not true control, but it'll give me piece of mind...

Re: New motor ready for beta testing

Start with the 5v wires if you can. The motor is a torque monster.

I'm still using the enclosure. But if this motor is more than 2x the torque of the original motor, I'm not sure it'll survive the experiment. Though that'd be a good excuse to replace the enclosure with a 2x4 and some hefty bolts.

So if it's got a square coupling, does that mean that there's no washer (yay!) and that it'd be a good idea to have a fuse on the motor to blow when it's working too hard? If so, any recommendation on the amount of current I'd want to aim at? Or is this "experimental" in the sense of "watch closely while it's running to see what it destroys first"? :-)

Re: New motor ready for beta testing

Square coupling means no washer. It is definitely not going to slip, so you either want to limit voltage or current (a fuse does the latter).

I'd aim at 2A for starters, but this is definitely a beta. Things could go wrong. smile

Nm (Newton metre) 28 Nm is 20.6517388 pound-foot which is a lot of torque.

vs the 12 Nm 8.8507452 pound-foot of the current motor which is stronger than the original motor I think.

Re: New motor ready for beta testing

I got the new motor. Sounds like I should pick up a circuit breaker and a variable power supply, before wiring it up. Your first post said 3A continuous, 10A peak. That's a lot of power! What current should the fuse be rated for - something like 5A slow blowing? 12A?

Re: New motor ready for beta testing

2A to start with, I'd say. It has a lot of torque and can damage the barrel if allowed to stall.

What do you think of RioRand (TM) 12V-40V 10A PWM DC Motor Speed Controller w/ Knob--High Efficiency, High Torque, Low Heat Generating with Reverse Polarity Protection, High Current Protection http://amzn.com/B007TH4EN6 ? Plus the power supply above should do the trick...

Re: New motor ready for beta testing

Does "High Current Protection" mean that it is fused?
