motor and driver compatible??

[nicotrial]

Hi il introduce myself my name is Nicotrial (it not realy my name its my nickname for the net) im from spain and im building a HOME MADE CNC!!!! WUHUUU!!.. i am thinking of buying this motors i found on ebay API M232-04-C2 STEPPER STEP MOTOR DUAL SHAFT
------------------

and this driver also found on ebay TA8435H Driver Board

ok now i am very NEW at this i started building my table (sort of based on the buildyourcnc.com website (well it actualy doesnt look anything like it).. and have it all finished now all i need are the motors.. so here is where i am stuck..
be easy on me im only in my first year of telecom engeniring on the university so not a pro on electronics....YET...... ok here i go..
*are these motor driver compatible?

*the motor has 8 wires and the driver goes only 4 and i find no technical documents of the motors on how to connect like many people in this forum find?

* i dont get the voltege thing.. the motor says Rated for: 4.3 VDC @ 1.8 Amps but the driver says Power supply: 12V - 24V DC Output current: peak value 2.5A per phase.. does that mean its 12 volts output and wont work with my motor???

*where do i plug in the limiter switches??

* i think thats all

well thanksss!!! ill keep you guys updated on how my build is going... if im on the wrong forum please move!!!

anyone

hello iv got more data on the motor and driver.. my biggest question is the voltage rating.. What does this mean.. i have found the wierin diagram too should i connect in series or paralel and what is the difference..

this is the stepper motor data
http://www.apicontrols.com/newapi/products/m23step.html

this is the driver board data
http://www.savebase.com/infobase/dow...435_Manual.pdf

and also this driver says
NOTE:
The interface of stepper motor shall be connected with 2-phase-and-4-wire/6-wire stepper motor (Model 42-57) within 2A current

can i still use this driver??

if not please recomand me a driver for these motors..

[nicotrial]

please answer somone i would like to finish my cnc!!!

Those are pretty small motors, how big of a machine?

Hi nicotrial
your motor got 8 wires means you can drive it bipolar or unipolar very flexible and the driver is enough to drive your motor. But at 100oz of torque it is too small to drive a cnc machine unless it is a super small and lightweight cnc machine.
You can connect it either in series or parallel difference only in at higher or lower speed.
Don't take this from me wait for otherss oppinion, I may be wrong

[nicotrial]

it is not that big and only for wood and small projects the motors do have 100 oz in torque so i think it will move the machine but do you think the driver is good for the motors???

[pminmo]

define not that big? what kind of screw or mechanics are you going to use? There are quite a few posts of users not happy with the TA8435H boards off of ebay.

hello im building a cnc similar to the one on the website builyourcnc.com.. it is a hobby cnc so im starting with very cheap stuff..(ill upgrade is i go and have the money) my screw is a normal 8mm screw that you can find at any shop for less then a 1€ for 1 meter.. it is 1x1 meter so its not that big and all made of wood aluminium and some steel for the rails.. i think 100oz is enough becouse i tried with smaller ellectric motor that i have here at home from rc cars and a small hand vacume clener motor and it moves it with no resistanse and you cant stop it either, by pulling or anything.. though since the screw is verry small it goes realy slow but with lots of strength.. thats why i thought 100oz would do.. and i saw many comercial hobby cncs that use 110oz in motors and where compleatle made of aluminium and looked very havy and about the same size.. thats why i guessed it would do on mine.. though it too late becouse i already bought them...

if by any chance the motors wont do if i buy bigger mottors would this driver still work?? i have no idea up tu how much you can put..

ohh and 15mgtar thank you for the info... and what would be the best way (in my situation) to wire the motors... ill see if i can get more info and if i buy it ill tell you guys how it went... well i hope this invention works....

nicotrial,
you want to wire them as bipolar parallel with it you will get higher torque at low speed vs bipolar series if I am not mistaken.

I suggest you spend a few evenings reading posts by pminmo, Mariss, ger, and some of the other senior members, pminmo has a lot of useful information on his website and Mariss's posts are very informative, check out the gecko faq. It is often easier and a lot cheaper to avoid pitfalls by doing your homework first.

ok thanks alot ill be wiering soon thank you all ill write back to tell how it worked out
