Other Parts Discussed in Thread: DRV10983, DRV10983-Q1
Hello Guys,
Good day.
Our customer is planning to use DRV10987 on their design. However, they are confronted with the following questions:
1) it is mentioned that the driver is driving motors with sinusoidal wave but all they see on the oscilloscope is controlling with PWM. Is there any particular setup for that?
2) How can they initialize the chip that can keep the speed under load? In the other word, how can they initialize the driver to increase the torque in order to keep the speed of the motor when the motor is loaded?
3) For a motor like:

what would be Kt and Rm values? It sounds like it is not possible to initialize exactly those values into the driver. In these cases, what do you suggest to do if they cannot initialize the exact Kt and Rm values into the driver IC?
Thanks in advance!
