Hi champs

I am asking this for our customer. 
the user is asking examples and/or app notes for FOC motor control using single shunt current sensing because of low cost considerations. 
Example on F28E12x is preferred. 
Example on F280013x is acceptable.

do we have such examples?

    F28E12 based sensorless FOC with single shunt is still in development.  F28E12 based sensorless FOC with 3-shunt will be in SDK in 3Q MCSDK.

     F280013x based sensorless FOC with single and 3-shunt have had example in MCSDK as below.

    You may refer to the Universal Motor Control Lab for the newer C2000 device in motor control SDK. The universal motor control lab is available in the current MCSDK, which can support a set of hardware kits and control algorithms for BLDC/PMSM drive. The kits include LAUNCHXL-F280025C, LAUNCHXL-F280039C,  LAUNCHXL-F2800137 with BOOSTXL-DRV8323RS, BOOSTXL-DRV8323RH, DRV8353Rx-EVM,  BOOSTXL-3PHGANINV, DRV8316REVM, or  DRV8329AEVM (single shunt) inverter board for low voltage motor (max: 100Vdc) with 3-shunt or single-shunt current sensing. TMDSCNCD280025C, TMDSCNCD2800137 , TMDSCNCD2800157 , or TMDSCNCD280039C with TMDSHVMTRINSPIN inverter board and TMDSADAP180TO100 for high voltage motor (max 350Vdc). And The control algorithms include sensorless InstaSPIN-FOC with FAST, Sensorless-FOC with eSMO, Sensored-FOC with incremental encoder, Sensored-FOC with hall sensor.
