Hi,

Does 3PHASELV-KIT board support a 2 pole motor with 40,000 rpm max speed? the datasheet for 3PHASELV-KIT shows it supports a 6 pole motor up to 3000 rpm, so for a 2 pole motor, I would expect it can support up to 9000 rpm. what about higher? can I set higher RPMs in firmware?

Can you indicate the ST product part number of this kit? Even just a link can be sufficient.

I think

STEVAL-IFN003V1

is a valid part number.otherwise look online on ST or digikey and you get the answer.

Thanks

Taking a look online seems that 3PHASELV-KIT is not an ST product, so please, if you have question regarding STEVAL-IFN003V1 (that is ST product) you can ask.

Thank you

Hello Gigi

my question is about the ST board

http://www.digikey.com/product-detail/en/STEVAL-IFN003V1/497-14123-ND/3946012

. with datasheet here:

http://www.st.com/web/en/resource/technical/document/data_brief/DM00040669.pdf

Please ignore the title of my initial post.

1) Can this ST board and its firmware drive a two pole motor with 40,000 rpm, taking that the power stage ratings are within requirements.

2) do I need any other hardware/ software other than the board and Jtag programmer to make this hole system work? (any debugger, special IDE etc?)

Thanks

Ok, sorry for the misunderstaning

Teoretically yes. Let's make two calculation:

40.000 rpm -> 666.666 mec Hz -> 1.333k el Hz

To syntetize the sinusoidal wave let say we need 20 point -> 26.6 kHz of control frequency

According last benchmark with the STM32F103 (that is present in the STEVAL-IFN003V1) the maximum control rate is around 23 kHz.

I think that shall be challenge but feasible.

To work with it you need to download the PC configurator and FW library (STSW-STM32100)

An IDE. Two are supported IAR Embedded Workbench and Keil

And the programming debugging dongle like ST Link, Jlink or ULink

In the

http://www.st.com/st-web-ui/static/active/en/resource/technical/document/user_manual/DM00028241.pdf

, the Quick start guide, you can find a lot of information.

Hi,

1) Are the keil and IAR environments included on the cd that comes with the eval board or they need to be bought separately?

2) The document UM1080 you referred to seems to be for a different hardware as seen under figure 9 on page 21 of UM1080. Does this document also apply to the STEVAL-IFN003V1 board?

Thanks,

Morteza

Ciao Morteza

IAR and Keil are third party software and you have to get it directly from their website. The free evaluation version should be sufficient.

The firmware and PC configurator descibed in the UM1080 are compatible with the STEVAL-IFN003V1. You can find in the configurator (ST MC Workbench installed STSW-STM32100) a specific example project to start with the STEVAL-IFN003V1.
