what is the exactly parameters of the NEMA17 BLDC/PMSM 55W Motor in DRV8312-C2-KIT

Other Parts Discussed in Thread: CONTROLSUITE, MOTORWARE

Hi,

I viewed this post(). However the parameters are different from the parameters I saw in the sample solution. Could anyone tell me which one is correct?

Does anyone know the parameters? Thanks.

#elif (USER_MOTOR == Anaheim_BLY172S)
#define USER_MOTOR_TYPE MOTOR_Type_Pm
#define USER_MOTOR_NUM_POLE_PAIRS (4)
#define USER_MOTOR_Rr (NULL)
#define USER_MOTOR_Rs (0.4051206)
#define USER_MOTOR_Ls_d (0.0006398709)
#define USER_MOTOR_Ls_q (0.0006398709)
#define USER_MOTOR_RATED_FLUX (0.03416464)

values should be in this range

Hi Chris,

The parameters I found in controlsuite are different. Do I need to change the code before running the motor?

#define RS 0.79 // Stator resistance (ohm)
#define RR 0 // Rotor resistance (ohm)
#define LS 0.0012 // Stator inductance (H)
#define LR 0 // Rotor inductance (H)
#define LM 0 // Magnetizing inductance (H)
#define POLES 8

MotorWare / InstaSPIN / FAST use line to neutral calculations. The controlSUITE / eSMO use line to line. Note that
0.4 * 2 = 0.79
0.0006 * 2 = 0.0012
4 pairs * 2 = 8 poles
