TMS320F280025: Starting point for sensorless drive evaluation

Part Number: TMS320F280025
Other Parts Discussed in Thread: MOTORWARE, TMS320F28027F, C2000WARE, TMDSADAP180TO100, TMDSCNCD280025C

Dear all,

A few years ago (2012-2013) we develop a sensorless drive using example in motorware and using TMS320F28027F.

For several reason, the final product was never commercialized but this was not related to the drive, the results with the drive were quite good (especially with help of ChrisClearman and 

Jorge Zambada), especially regarding low speed performance and flying start (reverse or forward).

In the coming month, we will start a new sensorless project and we will first start to evaluate the different supplier solution (including TI but also competitors).

I have spent some time to look all the documentation (C2000ware motor control SDK) and I want to be sure that I will use the right tool to evaluate the TI solution.

From what I can see, there is no longer need to use controller with specific ROM code as it was before, so we plan to use "entry" solution for cost reason.

Our choice for evaluation will be using TMDSCNCD280025C (+ TMDSADAP180TO100) which is compatible with the HVKIT we already have. Is it a good choice?

I plan to do the lab of this document https://www.ti.com/lit/ug/spruj26/spruj26.pdf , is it the best way to evaluate performance (low speed and flying start) with our own motor?

In level 2 what kind of motor should we connect? PMSM or ACIM?

In initial MOTORWARE, there was a GUI that was used to drive the motor (speed, direction and tune all KP,KI etc...) and show curves, I can't find any similar tool in Motor control SDK, I'm right?

There was a good guide for MOOTRWARE:

https://www.ti.com/lit/pdf/spruhj1

But according to this, it doesn't apply to C2000Ware MotorControl SDK:

Is there a similar guide for C2000Ware MotorControl SDK? I cannot find it.

Thank for your help!

Regards.

  • Hello,

    Our subject matter expert is currently out of the office, but he will be back tomorrow. Please be patient while he gets back to you.

  • Our choice for evaluation will be using TMDSCNCD280025C (+ TMDSADAP180TO100) which is compatible with the HVKIT we already have. Is it a good choice?

    Yes. The Universal Motor Control Lab has supported these kits.

    In level 2 what kind of motor should we connect? PMSM or ACIM?

    This lab only supports PMSM, so you may connect the PMSM in all of build levels.

    Is there a similar guide for C2000Ware MotorControl SDK? I cannot find it.

    There is no dedicated InstaSPIN User's Guide for C2000Ware MotorControl SDK. The https://www.ti.com/lit/pdf/spruhj1 can be still used for MotorControl SDK with InstaSPIN-FOC
