C2000WARE: For Sine control of BLDC motor

Part Number: C2000WARE

Dear Sir/ Maam

I want to control sine control of BLDC motor. I have hall sensor which gives the position and speed. Now what will be the control scheme for the sine control. How will i do field weakening. 

  • Injecting a negative current on d-axis if you are using sensorless sinusoidal FOC. You may refer to the lab for the C2000 devices 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-F280039CLAUNCHXL-F2800137 with DRV8316REVM inverter board for low voltage motor.  The control algorithms include sensorless InstaSPIN-FOC with FAST, Sensorless-FOC with eSMO, Sensored-FOC with incremental encoder, Sensored-FOC with hall sensor.  You can refer to the device peripherals (ePWM, ADC, eQEP, or eCAP) configuration for motor control with the other C2000 devices including F2838x.
