TMDSHVMTRINSPIN: Understanding the motor drive kit power range

Part Number: DRV8301-69M-KIT

Hello all!

What is the power that I can draw from the DRV8301-HC-C2-KIT at 18V? The data sheet says  18V to 60V, 60A  so can I draw 60A at all range of 18-60V output?

In the same manner:

What is the power that I can draw from the DRV8301-69M-KIT at 18V? The data sheet says  18V to 60V, 40A  so can I draw 40A at all range of 18-60V output?

Hello all,

Hi Marco,

Your three questions have been combined here in this thread since they are strongly related and will be answered soon. Thanks!

Best regards,
Chen

Marco,
the current range of each of these kits refers to the peak phase current.

For a 500W 36V application I would recommend
DRV8301-69M-KIT 60V, 41A peak (This is the InstaSPIN-FOC version)
DRV8301-HC-C2-KIT 60V, 60A peak (This is the InstaSPIN-BLDC and SMO FOC version)
or
BOOSTXL-DRV8305EVM 45V, 23A peak paired with LAUNCHXL-F28069M

Thanks very much, 

DRV8301-69M-KIT  looks good. Can I have InstaSPIN-BLDC with this? perhaps if I can buy a different control board or flash the InstaSPIN into the mictocontroller?

Please also let me know if I can use the same board for the lower voltages like 14V input. Or maybe just recommend a different board....

Marco

if you only want to do InstaSPIN-BLDC buy DRV8301-HC-C2-KIT
they are the same inverter board

or buy the -69M kit and add TMDSCNCD28035ISO for the controlcard for IS-BLDC

Hi Chen, I am not quite sure I like the way they are organized now as I do not get them answered thoroughly. to me it looks like bundling questions does not work quite well. it's been a while I have posted a bunch of questions and still, some of the answers are pending. if you're not happy with the way I like them to be asked I'd rather remove the questions that are not being answered in this post and ask them later so I can move forward. 

I'll remove them by Sunday.

Best,

Marco

Hey Chris,
So the 60V and 41A means the board can handle a continios 2460W load? It doesn't seem it's the case. right?
Could you please help he understand the ti numbers. perhaps an example of pwoer calculation would be helpful here.
1- what is the RATED CONTINUOS Curent and Voltage that DRV8301-69M-KIT can offer?
Another thing you can help me a lot with is
2- Say I have a 14V 500W motor (10Krpm drone application) what board/s do you recemmend for development kit.

Best,
Marco

1.
DRV8301-69M-KIT
measures
66.32 V max
+/- 41.25 A max

there are of course practical limitations on the voltage so that you do not over voltage the system, and there are practical limits of the continuous current rms versus the peak current.

2.
none of the kits is ideal for this motor, but DRV8301-69M-KIT is the closest.
all of the kits have some limitations in regards to the noise picked up on the sampling. For this kit it is quite old and we have improved our knowledge of proper board design and layout since then. For the Launchpad and Boosterpacks it is primarily a limitation brought about by the format of these boards / connectors.

my suggestion for your application is to quickly build a board specific for your application.

Thank you for your help, Chris. I ordered the 69M board for preliminary evaluation of the work and also I am going to design a power board later for the full range of power I need.

I am thinking to purchase a control board for next phase from ti and incorporate it with my power design so I can use "Motorware" to work out the control and also have the right size of the power stage. So can you advise on controls? should I pick one the control boards from the website or do you think it's better to design the control part too?

Best,

Marco

I would recommend your design to use a controlCARD slot and TMDSCNCD28069MISO
