RE: [CAD_CAM_EDM_DRO] stepper controller - help

Not quite correct. The 65V is the maximum voltage that the manufacture
recommend those motors to run at. Those motors have a per phase
resistance of 1.52 ohm so the actual voltage would be about 3.5V. So I
would recommend a 36VDC power supply up to 65V maximum. But if you use
the L298 then you'd better stick with the 35VDC power supply.

Hello everyone!



I have powermax II steppers.

powermax II 1.8° step

model: m22nsxb-jds-ns-02

Vs (dc) 65V

Is (dc) 2.3 A bipolar series

Po 104W

8 wires

torque 253 oz-in



http://www.pacsci.com/products/step_motors/powermaxproducts.html



What kind of controller and power supply is needed for get best of this
stepper? Is it possible to make at home such controller? I know that is
good to have multiple voltage power supply, so I guess I must have
around 140V power supply. But I don't know any driver chips similar l298
that can handle that much voltage.



Any advice?



Boris
