SM320F28335-HT: 24V motor development for SM320F28335-HT

TMDSHVMTRPFCKIT: 24V motor development for SM320F28335-HT

Part Number: TMDSHVMTRPFCKIT

Hi There

i'm looking at using the SM320F28335-HT for a high temperature motor application, i already have the TMDSCNCD28335 plug in module and TMDSHVMTRPFCKIT motor dev kit. The issue i have is thaat i'd like to interface to a 24V motor. (note, its unopened and i will send it back if not suitable)

Question 1) can i simply supply TMDSHVMTRPFCKIT with 24V DC? (i know its HV but the literature doesn't  specify a minimum voltage.

question 2) if the above isn't possible can can i buy a DRV8301-69M-KIT and simply change the card (from the TMDSCNCD28069MISO to the TMDSCNCD28335)? or is there lots of modifications i would need to make?

Kind Regards

    Q1, Yes, you can do this, just to use the 24V DC power supply instead of the AC power supply on P1 connector.
    Q2, Right, this is a good choice for low voltage high current motor, it can support all C2000 controlCard, just need to change the device configuration file on GPIO, ADC PWM... modules.

    Just an update for anybody else reading this post: i have now successfully used a 24V BLDC motor with dev kit, i will say as the GUI is sensorless the motor struggles o start and you have to help it get going - fine once its moving. i suspect at 24 the back emf resolution is very low at 24V

    kind regards
