Upgrading confusions

Postby kiark82 » Mon Jul 24, 2017 11:27 am

Hello!

i decided i wantet to upgrade my stepper motors. im using nema23s now, but they are on the low end of power.

Rated current: 1.7 A
Rated voltage: 6.8 V
Phase resistance: 4 ohm
Phase inductance: 1,4 mH
0.88 N·m, 125 oz·in

im using a 36v 10A power supply and as stated a gecko drive g540

now i want something more powerful and the problem i have is finding a good motor for it.

Some motors have 3,8mH wich would mean i need a 62V power supply, but gecko takes only 50V.

i couldnt find any motor that really fits, either the mH were too high or the A. it wouldnt be a problem to change the power supply.

what confuses me is, that i could find bundles with the gecko driver and 380oz-in motors at a 48v power supply and that didnt make any sense to me. im not very good with electronics though.

i dont want to change the motor on the Z-axis, does this make any problems with the rest of the motors/the power supply?

I hope somebody can give me a good suggestion.

Thanks,

kiark
