ZHCSDA7G July 2014 – February 2018 DRV10983
For the motor parameter measurement, see the DRV10983 and DRV10975 Tuning Guide.
The motor phase resistance and the BEMF constant (Kt) are two important parameters used to characterize a BLDC motor. The DRV10983 requires these parameters to be configured in the register. The motor phase resistance is programmed by writing the values for Rm[6:0] in the MotorParam1 register. The BEMF constant is programmed by writing the values for Kt[6:0] in the MotorParam2 register.
