    Sam Cho
    Hi TI, Can you inform if I can setup DRV8829 to run DCM, but only control it with ENBL and PHASE? Can you inform if I can use external resistor to set up 100% current? Regards, Sam,

    Dear Sir/Madam, We have a DRV8312-C2-KIT and played it for couple weeks. We noticed that the GUI (InstaSPIN-BLDC_GUI_DRV83xx_v104.exe) was reset in some conditions. We found this issuein the velocity control mode. We set the Ki to zero and adjusted the Kp. The motor cannot turn from static state...

  • Forum Post: RE: InstaSpin vs FOC

    Danny Miller
    I'm primarily interested in FOC. I have many potential applications. One that stands out is a direct-drive router motor, which may have two or even one-tooth tooling. The rotational inertia of this system would be low. As such the load and accompanying phase lag is highly variable with rotor angle...

    Matt Baxter
    I have a related question about the included motor: I'd like to use this kit for feedback control of a stick-balancing cart. For the feedback I intend to add a shaft encoder. Will the motor in the kit be double-ended, so I can mount the shaft encoder to the back while driving a load in the front...

    Jaime Boal
    Ryan, Thanks for your quick reply, but I had soldered the component correctly, the problem must be elsewhere. Let me explain the problem in more detail, as I have been carrying out several test over the last few days. I have ensured that the control signals for the MOSFET gates match those of the...

    Jaime Boal
    Hi everyone! I am trying to control a BLDC motor using the DKD8332. However, two of the three FET pairs of the bridge remain always active, which results in a short circuit between PVDD_X and GND_X. The short cirtcuit persists even when the device is not connected! I have checked the control signals...

    Hello, I am reading through the datasheet for the DRV8332 and there is a section regarding Under Voltage protection. Is there a similar feature for Over Voltage on the VDD input? What is the failure mode of this part if VDD goes beyond 13.2V and how far out of spec does VDD need to be before damage occurs...

    Hello, I recently completed a test that required control of eight BLDC motors (48V/5A/10k RPM) using eight DRV8301-HC-C2-KIT eval boards running lightly modified Instaspin software and a Stellaris Launchpad to control them all over SPI. This worked well, but required a huge box, so the next stage of...

    satish bhogineni
    The motor that you are supplying with DRV8312-C2-KIT is 1 NEMA17 BLDC/PMSM 55W Motor. When I see details of the motor it is a delta connected motor, it can not be used as BLDCM. Here the phase currents will be there through out 360 and sensorless control have problems. It is not a practically used...
