As someone who is planning on purchasing four of the 900W motors, I'd be very interested in the 100V driver they are working on. Do they plan to release a power supply to pair with it?
I don't plan on purchaing until 2-3 months from now. Think it might be available by then? I would hate to buy the 50V version and then have the 100V come out shortly after. Also how much of a price increase are we looking at (ballpark)?

At this time The 100v Drive Has changed track, it now will/is 120/240V AC input, there will be no need for a power supply, but this drive is just in the build stage, the front end is all done,
The Dyna-2 has also changed, & is now a max of 75V DC it would be good to run around 65V DC to the motors, These are being made right now, This will improve the performance of the 7.2Nm motor as well to around 1350RPM
Wow, very interesting! I guess we'll see what is around 2-3 months from now.
Hi Mactec
I have a new build started and will be using DMM Technology package
"Peak 7.2Nm(1015 OZ-In) high torque AC servo motor, 3 Axis CNC kit for MACH"
With the new drives being made, you said the rpm will be around 1350, but what about the torque?
I included a picture of the system case I'm putting together.

Mactec,
I was looking at torchmates machines and they give you two motor options for the same machine. You can order it with either a 380 oz. inch. stepper motors or 152 oz. inch. servo motors. I'm curious, do you know if a AC Servo torque 1015 oz = 1015 oz Stepper motor? Based on what torchmate offers it seems as though a servo motor is more than twice as strong as a stepper motor.

I have the price quote for the 3 axis 300 watt setup and will order as soon as I can get payment details.

Servo motors are rated in watts & N-m or in-lb, Only very small servo's will have a N-m oz-in rating listed, although you do see people using oz-in they have converted the in-lb to oz-in,to try & get a comparision, But this does not compare the two,in terms of performance
The one you posted at 152 oz-in would be around a 250watt motor, If the 152 oz-in is the rated output, but most likely is a DC servo with brushes, These are not the same performance as AC servo's
A Servos that is say 400W (.53hp) Rated output 181 oz-in, Peak output 542 oz-in
Will a pair of DMM 900Watt servos move my 500lbs gantry at decent speeds and have enough torque?I understand it is a vague question.I would be using 12DP R&P with 2"

Larry, check out the latest post in my build log. I have some number posted dealing with acceleration of a 700lb gantry.Originally Posted by lgalla
Depends on your definition of "decent," but the likely answer is yes.
Mactec,
Is there any time estimation on that new drive w/ 120V/240V be released? Do you think in 2 or 3 mo's be available?
I thought I had come back to reply with my experiance with the DMM servos' but I see I was mistaken.
Let me start by saying the tech support was outstanding and all my questions were answered promptly. The documentation was clear enough for a first time CNC person to have everything up and running with only 2 emails for help.
The documentation walks you through the Mach 3 setup with pictures and text.
I am extremely happy with my purchase!!!! The system runs very quietly compared to the whining I here on other video's from stepper motors.
Here are some video's of my first cut and some other things:

Thank you DMM !!!!!
Very interested in the timing on the release of the 120/240V controller.
Looking at a 300W 200V AC servo application.
Any updates ?
