Newbie help, looking to set up cost effective servo/drive setup to backrun motors.

[Harryp]

I am building a test stand to backrun motors and am looking for a drive and motor setup with potentiometer speed and switch direction control. Could someone recommend me a drive and motor that wouldn't cost an arm and a leg. I've seen various packages on ebay but am not sure if I will be able to get the software for the drive anymore. Any input would help.

I'm not sure but this could be what you are looking for,you can run these with Mach software

Motion Control Products - DMM Technology

Thanks but thats quiet expensive for my application my budget was 5-600 trying to fish a deal on ebay.

How many axes do you want,one Axes from Dmm is only around or better than $300 or well within your $500/$600

You didn't tell us how powerful the motors to be tested are.

As Mach can run a step/dir drive at constnat speed and direction, you could do this job with any Step/Dir drive and a cheap PIII-1000Mhz or newer computor.

GECKO or CNCDrive both offer a range of Step/Dir drives. CNCDrive offer much more powerful drives, and also Servos to go with them. I bought the USERVO system from them, and was very happy with communications and delivery from them. There is a test on the web where some guy tested all the different Step/dir servo drives (CNCdrive/Gecko/Viper/Granite etc) and the CNCdrives came out on top.

How much torque do you need? I may have what u need. I have four running Drives Bosch Rexroth Ecodrive DKC1.1 with different size Servomotors. I can set them up for you so you can switch direction then using potentiometer for torque and speed.

Thanks guys I got my hands on a Yaskawa Servopack Drive SGDH-30DE now the question is would it be compatible with a SGMGH-44D2A61 UTSAH-B17BB motor :S

The torque on those motors seems real low, I need atleast 3000 rpm not sure about the torque but I'd guess 5-6 ftlbs? Its a test bench to back run motors to test ke value.

No they are not compatible,you would need for that motor SGDH-50 Drive

The SDGH-30DE drive is 400V, so you would need 400V 3 Phase to drive it

These are very large HP motors/drives you are looking at, what are you going to drive with them

[Harryp]

You are right, looks like I picked the wrong drive the motors are way too expensive. There is a list of matching drives and motors here if anyone needs it.

Why do you need an intelligent drive that requires software?
Surely you can use a simple PWM drive with analogue (10k pot) input.
There are many Advanced Motion on ebay that should do the trick.
A servo motor with an encoder back to the drive will maintain the rpm.
These drives you can get with self contained power supply up to 100amp drive.
The BLDC types will drive both BLDC and brushed DC motors.
The 25A20AC should be sufficient for what you want to do?
