Hello, I am using a DRV8312 Kit, TMS320F28035 chip and am running the PM_Sensorless project.
In this sensorless project i modified build level 4 to test an encoder as i require to go pretty slow and the smo/se macro works iffy below 120 rpm.

We have seen that happen, can depend on unpowered breakaway torque of rotor magnets to stator laminations. Check the lock rotor flag is not enabled at any point for SPM or…

Other Parts Discussed in Thread: DRV8312 , INSTASPIN-BLDC Hi all,
I am studying about methods of controlling BLDC motor (type of trapezoidal back-EMF synchronous motor). I also tried to control a BLDC motor with a TI's evaluation kit named DRV8312 C2…
Hello Maria,
Using the values from user.h, and userParams.h, i'm trying to form the transfer functions of s , F(s), so i can generate the block diagrams of the complete control system (motor and PID), so i can model that in Matlab/Simulink. I have mathematical…
Hi Chris and Jorge
I made the changes suggested by Jorge and the phase current starts to look sinusoidal. I had a Compiler 6.2.3 (I thought that it was enough) and I update it to 6.2.6, the figure below shows the before and after the updates:
Figure1…
I have a quetion to inertia calculation as well
i am using DRV8312EVM Rev D and the Anaheim Automation BLY172S motor that comes with the kit.
From Anaheim-data the Rotor Inertia is given J = 0.00068 oz-insec^2 = 0.00068*0.00706 =4.8e-6 kg m^2

Other Parts Discussed in Thread: MOTORWARE I arrived at the lab 06c but I do not understand how to change the values of the function STVELPLAN_addCfgState STVELPLAN_addCfgTran where can I find a full explanation what it means _IQ (0.1)
how do I know…
