Hello,
I'm developing a gimbal application and planning to use a DRV10975 for motor driver. Since I'm using a gimbal motor which provides me high torque, almost all of the gimbal motors do not have a hall sensor feedback. That is why I was planning to use sensorless sinusoidal driver DRV10975. I tried to spin motor but realized initialization of the motor is little bit worse since driver starts spinning motor in open loop. I'm wondering that I have an absolute encoder which is located in motor shaft. I'm also using motor as direct drive so which means that I have a rotor position feedback actually, can I use this information to start motor rotation better via sending this info through I2C.
Or, do you have any other recommendation to use another chip for this kind of application. But, mosfets, drivers and commutation logic must be in a single chip. I can provide the speed command and direction from another controller.
Thank you
