TMDSCNCD28069MISO: BLDC motor driver for a 36 pole three phase BLDC using TMDSCNCD28069MISO and half-bridge motor drivers

Part Number: TMDSCNCD28069MISO
Other Parts Discussed in Thread: TMDSHVMTRINSPIN, TMDSCNCD280049C, TMDSADAP180TO100, TMS320F280049C

Hi Team,

We have a customer looking for a BLDC motor driver for a 36 pole three phase BLDC washing machine motor having ten inch diameter with permanent magnets on the rotor using star configuration windings at terminals. He needs approximately 3 horsepower of torque with capability of 3600 rpm max at motor shaft. He have seen a working device consuming approximately a little over 1 amp at slightly over 400volts.

Can we use TMDSCNCD28069MISO together with the half-bridge motor drivers below for this application?;700



  • sure, you could.

    As a starting point you probably want to start with an EVM like TMDSHVMTRINSPIN to try out the solution (with the limitiations of this EVM) first.  This EVM comes with the 69M controlCARD.  You use for the software.

    This is an older product family. There is a newer version similar to this 69M device called TMS320F280049C.  It has a controlCARD TMDSCNCD280049C that can be used with this same EVM - by using an adapter board TMDSADAP180TO100  - and it uses for the software examples.

    good luck~
