Hi!
I have searched a lot and cann't find specification for that MINEBEA stepper motor.
I know that it's a unipolar stepper (6 wires) and as I measured resistance it's about
7 Ohm PH. So any help is appreciated.

Thanks in advance.

PS. Here is all what can be read from motor

Hi,

this site has(d) the info:
http://www.eminebea.com/content/html...or/index.shtml

but I can't open it now, maybe their server is down?

If you can't access it in the near future: I have several similar motors and might have printed or noted down info, just let me know.

Thanks for your answer.
I've searched their site and can't find docs for PM-H series
As I can see H series is also "hybrid" not "permanent" type and the base of the motor
is quadratic not circle.

I have attached image of motors label ...
In the mean time, I buy digital multimeter and measured resistance of coils. So from
the one end to the middle tap, resistance is 7 ohms. Motor has 6 wires.

After reading similar specifications for the minebea motors, I can suppose that current can
be about 0.6 - 0.8 amps but it would be much nicer to have original data.

Thanks in advance.

You probably have a custom motor, finding the exact data will be difficult if not impossible.
This page describes the model number digit information:

You will have to compare with a similar motor and eventually start driving it with lower amps and increase if needed.

hi
info for just helping you thank's

[PatriceRene]

Did you get the specification of this stepper motor
I've 2 motors of that type
Regards

[Ernst]

I have a home build CNC machine with on xyz axis steppermotor type
34PM-c042.

It seems the max stepping rate is about 1500 steps/sec. I don´t know if this is rather low or high? In the software I set 400 steps for 1rev, to move 2.5mm. The max speed to calculate is 9.375mm/sec.

The motor gets 2Amp. (This is not measured but a controller spec.)

Looking for specifications to. Wondering how to increase speed.

hi
i searched alot but i didn't find datasheet of 17PM-M008-10V stepper motor
can any one help me
how i can get detail about the features of this stepper motor
following data is written on the stepper motor i bought
i need to know about the current rating, step angle and voltage rating of this motor
