TMDSHVMTRINSPIN

Hi Rich,

I have moved your thread to the C2000 forum as they will better be able to assist you.

Hi Rich!

I haven't an experience in this area, but I would recommend you to describe your issues in details. You will get help faster.

Regards,

Igor

yes, I have quite a bit of experience using it. Just ran a washing machine motor on a dyno last week as well as a induction and high voltage BLDC used for opening gates arms.

I'll move this to the InstaSPIN forum as well.

Actually, what is the difference bet. this kit and DRV8301-69M kit??

It seems to me that both are based on Piccolo C2000 and InstaSPIN-FOC/MOTION. Also, both can drive ACIM, BLDC and PMSM. So, just at different power level?

TMDSHVMTRINSPIN
50-350V DC Bus (you provide bus or 110-230Vac input which is doubled to provide bus)
10A max
controlCARDS: TMDSCNCD28069MISO (InstaSPIN-FOC & -MOTION) and TMDSCNCD28027F (InstaSPIN-FOC)

DRV8301-69M-KIT
15-60V DC Bus (you provide bus)
40A max using the InstaSPIN software and external op-amp scaling. Can be changed to ~100A if required.
controlCARD: TMDSCNCD28069MISO (InstaSPIN-FOC & -MOTION)
you can use TMDCNCD28027F with this kit but you need to purchase an external emulator, like the $79 XDS100v2 from the eStore, and you should consider an Isolated version.

Both are fully supported through MotorWare, and the GUIs included in the www.ti.com/tool/motorkitscncd69miso download works on both kits with the 69MISO controlCARD.

I have an application for a compressor with the following conditions: bldc-750W- 270Vdc-3 phase-5k rpms-sensorless bemf FOC-10 poles-closed loop.  What is your estimate on the likelyhood that this TI MC kit will be able to run this motor and how much of an effort is involved ?  Right now I have another MC kit (not TI's) that looks like it can't handle this type of application.  I have spent 6 months with help from the MC application engr. and we basically gave up.  Note, a compressor has special dynamic torque requirements especially at startup.

Rich,

TMDSHVMTRINSPIN and InstaSPIN-FOC will handle this with ease. We are controlling many compressors today.

Yes, you will have some challenges, but they will be overcome.

1. Initial motor ID. This needs to be done with the motor unloaded and unconnected to any gearing/compression. Hard to do in a sealed compressor, right?  There are ways around this...I just reposted this information here.  If you are able though to do the motor ID on just the motor (or you already know Rs, Ls, and flux) this is not a concern and you can start right up.

2. start under full load. Please see Chapter 15 of SPRUHJ1 (User's Guide). 

3. highest speed operation into full over-modulation. With some applications we have seen some hardware design / sampling issues with highest speed operation (moving out of SVPWM and into trapezoidal modulation).  We are looking at some enhancements to the sampling, but you can operate at just under full speed with no issues, and no problems with "full speed" SVPWM.  Recall that you are responsible for testing the current controller (at high speeds and for stiffer control increase Kp up to 4x) and tuning your speed controller.
