Other Parts Discussed in Thread: DRV8823
Dear TI Experts
We are using DRV8823, when the temperature is -40℃,the motor is hard to start!
And the motor supplier told us to increase the input voltage to increasing Motor Torque,now the driving voltage is 18V
1. If we increase the voltage, eg 32V ,the designed driving current is constant, can the output torque of the motor be improved?
2. If we increase the voltage,Will the internal current loop become unstable, affecting constant current drive?
3.Comparing the two ways: increasing voltage and driving current by changing resistance, which way is more reasonable to improve motor output torque?
