New User Looking to Configure STEVAL-IPM30B with ST32

[beheisey]

I am a new user looking to configure the STEVAL-IPM30B evaluation board to drive a three phase dc motor.  I am uncertain which of the many STM32 boards I require.  Also, what type of cable is needed to connect the two boards?  My application requirements are basic on and off control of the motor at different speeds with open loop operation (I am using a three phase stepping motor).

Hello @beheisey , to know the boards compatible with the STEVAL-IPM30B in the MCSDK, you can download the mcsdk at this link:X-CUBE-MCSDK - STM32 Motor Control Software Development Kit (MCSDK) - STMicroelectronics
Then launch the Workbench and finally select your STEVAL-IPM30B on the power board, it will offer you compatible control cards, be aware that if you choose a NUCLEO you should taking a Bridge.

Hello @beheisey ,After rereading your question, I would like to add that our MCSDK solution offers to do Openloop in FOC but not stepper.
If you want to do a stepper, it won't work.

Dear Zied,

Could you please tell me that  STEVAL-IPM30B power board can be used in 24-48 volts range?

Datasheet said operating voltage is between 125-400V.

I just wanted to test in low voltage first. Then i will go to high voltage.

Hi, @Zied b. 

Is there anything else than the bus voltage divider (126.33) that limits the voltage range to 125V? This divider would give a low SNR for lower voltages. But I can't find anything else in the schematics that would limit the voltage downwards? Also the IC does not specify any lower limit.

Hello @Lukas47,

The bus voltage divider ensures that the +3.3V ADC input is not exceeded for the DC bus voltage measurement.
You can use the STEVAL-IPM30B at voltages lower than 125V. This value ensures optimal power board performances.
