23lm-c355-p6v

[ozan]

Does anyone know the specs of this Step Motors, V/Phase and A/Phase values does not exist on labels, i checked many. I contacted with Astrosyn and Minebea, Astrosyn said that this is a motor produced by Minebea, searched on their site and saw closer models but not this one with C355, i mailed Minebea but no reply from them for weeks.

Found a site, he does some work with desktop-cnc and he uses "23LM-C355-P4", on the site it says "2.6V / 2.0A" for P4 ones, but not P6 again

Thanks.

Hi

by any chance you have spec sheet for 23LM-C355-P8w and 23LM-C355-P9V steppers, They have 6 wires so i am guessing they are unipolar, i have checked the Winding Resistance with a multimeter and they are 2.2 Ohm, but wanted to know the current rating.

Thanks

is that stepper useful to a cnc machine? i live in argentina and its hard to find good steppers. i would really apreciate if you could send my the pdf file.
thanks

I found this document also which describes that particular Unipolar Astrosyn 23LM-C355-P6V http://www.asr.org.tr/pdf/Vol14No2p139.pdf

I found one of these steppers in a junkyard Lexmark 2831 Plus Forms Printer which drives the dot-matrix print head. Another pancake stepper (55SPV2505NA) drives the paper feeder and is a 7.5 Deg. 8 Ohm coil with a gear. Lots of other goodies which can be cannibalized - toothed belt/pulleys, .54" dia. (14mm) shaft x 18", bushings, 1.5A driver chips/transistors, power supply etc...

Most of my CNC is comprised of recycled printer parts, and the bigger/older the printer the better steppers they have. Big enough to make a Dremel based router and hopefully manage a palm sized router when I get it developed to that stage.

I too would like the datasheet for a 23LM-C355-P9V stepper motor, they should be 1.5A but I'd like to check!

[mrgadgeteer]

Liander, if you refer to firat kocak's post in this thread the "P9V" suffix indicates the drive pulley or gear pressed on the shaft the type of connector on the motor. I would suspect that it will have the same specs as my "P6V" as I use. I use this to run a Z-axis and 1/4-20 threaded lead screw with no more than a Dremel tool for a load (or a small laser). There seems to be very little documents available so best 2 out of 3 searches says it is a 1.5 amp/coil motor. It is also a unipolar (only type I use so far).

From the PDF link I posted which agrees with previous postings:
MARCA MINEBEA Co. Ltd – ASTROSYN, Stepper Motor, Type 23LM-C355-P6V
Rated Current: 1.5 Amps Detent Torque Nm (g-Cm): 0.0540 (550)
Winding Resistance: 2.2 Ohms Rotor Inertia (Kg-Cm2): 0.110
Inductance: 5.5 mH 1.8 Deg/Step
Holding Torque Nm (Kg-Cm): 0.614 (6.2) 200 Steps/Rev.

Good luck, Mike

Thanks Mike, I've done a few tests and they seem to be 2 ohm per winding and 2A though, they have an IBM P/N so maybe they are a custom order?

[mrgadgeteer]

Mine also labeled with Astrosyn, and Minebea, made in Taiwan. They could have been custom order for Lexmark, but also may just be "extinct" under that numbering system. I found this also (Google is amazing) with very similar specs in Minebea catalog - look at 23KM-K355U http://www.eminebea.com/content/html...pdf/23KM-K.pdf

I think you are close enough with the data at hand to be able to make an educated choice how to drive it.

[Liander]

thank you very much for the help!

If I can get a copy of the Data Sheet for the MINEBEA 23lm - C355 stepper motor.

I am trying to identify the correct external wiring. This unit appears to be hard wired I would like to validate the A A\ B B\ pairs and polarisation.

Could this Minebea stepper motor 23LM-C355-02 be used on Proxxon MF-70 with the
·3 Axis CNC Stepper Motor Driver Board Controller TB6560· found on ebay？

I pulled a few of these (23lm-c355-17) motors from a printer and am building a small cnc router, but there was no information out there, so I figured out the wiring.

The wiring is as follows:

blue a+
tan a+
red b+
black b+
yellow b-
white b-
green a-
