Which controller for this stepper motors?

[toneV8]

I have this stepper motors
I find them from old printers some stepper motors:

It is manufactured by Tokyo Electric Co., Ltd. - I have 9 stepper
Model: Sph-54C-8
Name : TEC CLA45-50101
Specifications:
voltage - 8V DC
resistance - 10 ohms/phase
step angle - 1.8 deg/step
6 wires

It is manufactured by Kyushu Matsu****a electric Co. Ltd -I have 1 stepper
C??45-01102
Specifications:
voltage 3V
resistance 3,5 ohms/phase
step angle 1.8 deg/step
6 wires



It is manufactured by Tokyo Electric Co., Ltd - I have 5 stepper
Model: SP-55a-16
Specifications:
voltage 16V
resistance 65 ohms/phase
step angle 7,5 deg/step
6 wires


It is manufactured by Fuji Electrochemical Co. - I have 5 stepper
Model: SM55-4813A
Specifications:
voltage 16V
resistance 65 ohms/phase
step angle ( do not know )deg/step
6 wires


Now question is:
1. which of them to use for small cnc mill maybe foam milling
2. what kaind 3 axis controller to use with this motors
3.how to know does it unipolar or bipolar motor
4.how much steps
5.how much torque

I already have machine design so I want now start with electronics

Please help me with electronics.
THANKS!

The good news: all the motors are 6 wire so you can run them either unipolar or bipolar. The bad news, I doubt any of them are very powerfull. The 16V coils are probably the least powerfull of the bunch. The first two might be strong enough for a real small machine, but it will have to be mechanically very efficient (real low friction, high efficiency rotary to linear conversion).

Before I could make any recommendations, I need to know how accessable parts are for you?

[toneV8]

Accessable for parts I think that I will manage somehow.

So what kaind 3 axis controller to use with first two motors.
I would like to use stronger controller because later on I will use controller for bigger machine, bigger stepper motors......... This machine is only for learning stage.

[PMinMO]

if you can get SLA7062's that would be my recommendation right now.

[toneV8]

So I need 3x SLA7062 ''Part list''. Approximately how much cost ''Part list'' for each SLA7062 Driver Board.

- on Allegro SLA7062 Stepper Driver Board does it possible connect limit and Estop switch and LED's for those switches
- do you have PCB's for Allegro SLA7062 Stepper Driver Board
- do you have schematic for connections 3xSLA7062 Stepper Driver Board with parallel port



parallel port

1axis 2axis 3axis


-when assemble all parts from ''Part list'' on PCB do I need test something: voltage,resistant..........


Sorry for my ignorance aboute electronics because I am beginner in this.

[PMinMO]

I would estimate the compenets to be less than $10 per board plus the cost of the sla7062 chips.

Use the 4 axis interface on my website to interface the parallel port to a PC, switchs, estop....

I don't presently have boards for sale on the sla7062, plan on it in the future.

[toneV8]

With 3x SLA7062 Driver Board I also need tu build 4 axis interface to connect 3x SLA7062 Driver Board.

-how much ampere....... have 4 Axis interface board from Chris, does it Unipolar or Bipolar.

[PMinMO]

The sla7062 is rated at 3A up to the 46V max. Chris's 4 axis interface is fine. You don't need the all the voltage regulators. The interface has no implication on the unipolar or bipolar driver. The sla7062 is unipolar.

[toneV8]

PMinMO: what you thing about this 3 axis unipolar stepper motors.Does it 1.25A per phase or total on board. FrankG at http://www.theworkshop.ca build this board using printer stepper motors.


http://www.electronics-lab.com/projects/pc/008/index.html

[PMinMO]

It should work, there is no current limiting so you either have to run with power resistors or accept the performance of the stepper at its rated voltage.

[toneV8]

Sorry to bother you so meny times.

Do you know something about this 3 axis unipolar stepper motor driver kit.


Does it wisely to conect my motors on bipolar driver board and how much torque will get. How much torque in percentage.

[PMinMO]

That is a HobbyCNC kit. http://www.hobbycnc.com Contact Dave at HobbyCNC and he can give you the details.

3 Axis HCNCPRO Driver Board Kit $79USD + $15 S/H Int'l Orders is little expensive because machine I plane to build cost me ~80$. Where can I buy sla7062 and how much cost.

What means on this web page '' request samples''
http://www.allegromicro.com/sf/97060/

[PMinMO]

Allegro supplies samples at no cost to projects that they believe will sell more of their product.

I can't advise you on the torque, too many variables.

[toneV8]

To build 3x SLA7062 Driver Board I need 3x SLA7062 Translator/Drivers.

So I need to request samples for 3 ''SLA7062MLF2102''.
What means this note ''MLF2102'' addition to SLA7062.
