A 33VAC transformer will give you about 46VDC.īe sure to use enough capacitance to smooth out the ripple. A 30VAC transformer will give you about 42VDC. I would prefer a 500VA toroid transformer, although I have used a 250VA without any heat problems. My test bench theories are based on tests, not on long term usage. Remember that the G540 is limited to 50VDC. Anything in the 40VDC to 50VDC range will work very well. I agree with Brad about the power supply.
This forum as been an inspiration for so long and all the information in there is just gold, can't wait to start getting my hand dirty Are we going to sacrifice too much trying to save money ?Īnd last question is about the powersupply, would a 48V 12.5A be a good choice if this setup work ? are those motor with the belt reduction drive going to be strong enough for the mechmate or they will most probably overheat or die prematurely?ģ. will the speed be reduced too much to be efficient to drive the mechmate properly?Ģ. but the price!! 69$ eachĪfter seeing a couple post on belt reduction drive, I was wondering if those motor would work on a mechmate using a 4:1 ratio to increase the torque.ġ. the downside is the torque is only 465 oz-in. You can see the spec here the motor is a nema34 rated at 3.5A with an inductance of 4.2mH which make it perfect for the G540. I was thinking of reusing the G540 and get 4x K元4H260-35-4B We are currently using a G540 with a 24V power supply to drive 4 small nema24 stepper, for sure the powersupply will need to be upgraded and the nema24 are way too small to drive the mechmate. Me and a friend finally decided to seriously start putting on paper everything that we need to build one and see if we possibly can reuse stuff we already have in hand.
I have been browsing thru those forum for about 6 month's in the hope of one day start working on my own mechmate to replace my current cnc machine.
