Has Anyone Out There Delt With D.mauch For Stepper Motors. These Motors Are Rediculously Priced To Sell. Just Wondering What Strings Are Attached. This May Be Legit

I've not personally dealt with Dan, but many here have. I've seen a few people post that have already purchased some of these motors. He has a very good reputation in the community.

Can you post a link? I am sure someone here will know somthing about them.

Thanks.

I have bought motors from Dan before. Good motors, as advertised. No problems, good service.

34-026 Step motor 692 oz in 5A .62 ohm $89ea 6 avail

34-027 Step motor 785 oz in 2.5A 3 ohms $80 ea 22 avail

34-028 Step motor 802 oz in 5A .8 ohm $95 ea 16 avail


how come 34-027 is cheaper than 34-026? 34-027 has higher torque than and 34-026.

[Cold Fusion]

It seems that 34-027 has a lower amp rating and therefor a reduced power curve.

DAN is a great guy... not only sold me 3 great 280 oz steppers ,,, but he even took time out to email me a wiring diagram specific to my driver board...

The motors to be watching out for will be the 34-103 ones.

Dan Mauch sent me one to run dyno and linearity tests on and I'm very impressed. I have yet to run an instrumented linearity test but preliminarily I can say this is the smoothest motor I have ever tested. You cannot tell it apart from a servo.

Speaking of servos, it has power similar to a servo as well. The motor is an 8-wire single-stack NEMA-34 rated at 3A series, 4.3A unipolar and 6.1A parallel, having 452, 326 and 452 in-oz holding torque respectively.

My initial dyno test was run with the motor wired in parallel, current set to 4.3A, a 60VDC power supply and drive provided by a G201. Here's the inital dyno results:

Full Steps/Sec__in-oz___Watts (Power output)

500-------------312-----34.6
1500------------300-----99.9
2500------------270----149.9
3500------------217----168.6
4500------------180----179.8
5500------------150----183.2
6500------------127----183.3
7500------------108----179.9
8500-------------93----175.5
9500-------------81----170.9
10500------------71----165.5

This motor has a nearly flat power curve from 3,500 to 10,500 full steps per second (1050 RPM to 3150 RPM). Power peaks at 183 Watts; exceptional for a stepper.

Thanks All, I Went Ahead And Ordered Three. I Like When People Can Offer A Fair Price And Not Let Gread Get To Them.
