DRV8412-C2-KIT -- The stepper motorNo Data Sheet for Stepper Motor

Hi Gary,

The information you are looking for can be found at:

C:\ti\controlSUITE\development_kits\DRV8412-C2-KIT_v131\Stepper\~Docs\Microstepping.pdf

See Page 9: Anaheim Automation 23Y106S-LW8

The documentation can be found by opening controlSUITE
Then expand English -> Development Tools -> Motor -> DRV8412 Integrated Motor Driver for Brushed and Stepper ... -> Documentation -> Microstepping

Also you can find here

The TelcoIntercon motor should have similar specs.

Of course I saw the Anaheim motor's specs.

"The TelcoIntercon motor should have similar specs." -- isn't very helpful. The motor TI sold me has 3.0A marked on it. The Anaheim motor says it's 2.1 amps. The inductance and resistance do not match either. That's not "similar". Of course, the marking on the TelcoIntercon motor doesn't indicate 3.0A at Unipolar, Bipolar Series or Bipolar Parallel.

What is the problem with getting the spec to the motor TI sold me? Why is this so much trouble?

This kit cost $200 and did not include documentation on the stepper motor. I am writing software for the driver and need to be able to evaluate the motor's performance under my software and against its specs.

Telco Intercon says they'll provide specs to me if TI says it's "OK". Why can't someone just get the spec from them, or tell them to release the motor's specs. It's ridiculous to sell an eval kit and then keep the motor data secret or unavailable.

The motor TI sold me is part number is 4T5618M3008. Manufacturer is TelcoIntercon. (telcointercon.com)

If TI had indicated there would be no specs for the stepper, I wouldn't have bothered to buy the kit. I bought it to save time, but it has been nothing but a waste of time hunting this stepper datasheet.

Gary,
this kit originally did ship with the Anaheim Automation motor that Rick linked. Anaheim has had issues over the years in meeting deliveries so our manufacturer of the kits got a different source from Telco. Telco is obviously supposed to be providing an electrically identical motor, so I'm surprised to see that you think the specs are different.

I sent an email to our CM to see if they have or can get a datasheet on the specific motor that now ships with the kit.

I understand. I'm just surprised that Telco has "orders" to not disclose the data sheet.

The Anaheim website's Torque Curves exclude the 23Y106S-LW8 as well as the other 23Y1xx models. I can live with the Bipolar Series at 2.1A if that's what the Telco motor is. It would be nice to see the expected Torque Curves (with step resolution and voltage).

When I program the IC for the current rating I don't want to be over or under driving the motor. This would make it difficult to develop anti-resonance routines and other stepper-related algorithms.

I appreciate the help, but I still don't understand why Telco just doesn't get instructed to release the data sheet. Their website recognizes the part number. The 5618 is a family of steppers they sell, but this part number has no data sheet on their site.

I talked to their tech support who informed me that motor is a TI exclusive. Further, without TI's approval they will not release any information about it. I told him that the motor was provided in an Eval Kit and is rather useless without the data sheet, but they insisted I contact TI.

They don't have "orders". This is a custom motor for them so they don't publish the material like their off the shelf products.

If you want to blame someone blame us (TI) for not including either in the kit or as a link on the website for the tool.

It's just what the guy said, but jokingly.

CYNTHIA - THANK YOU FOR THE DATASHEET!
