TMS320F28034: How to make HVPM Sensorless project to support IPM motor?

Jack Tan80

Part Number: TMS320F28034

Dear Champs,

The HVPM Sensorless from controsuit are just has one parameter(LS), stator inductance. If the motor is IPM, that Ls-q and Ls-d are provided and different, how to configure this parameter in this settings? Thanks...

// Define the electrical motor parametes (Estun Servomotor)
#define RS 2.35 // Stator resistance (ohm)
#define RR // Rotor resistance (ohm)
#define LS 0.0065 // Stator inductance (H)
#define LR // Rotor inductance (H)
#define LM // Magnatizing inductance (H)
#define POLES 8 // Number of poles

The example project is for non salient motor which has Ld=Lq. If the Ld and Lq are different, it is usually ok to use the average value of Ld, Lq for each axis. This may lead to a little error in angle estimate, but should be ok for most speed ranges and applications.

Ramesh,

Thanks for your comments. I will try with your proposal.
