Hello, I am trying to control a bldc motor. But encounter a problem.
In OPEN loop, when I send PWM with duty cycle increase gradually(from 5% to 80%), motor works fine. But when I assign directly 80% duty cycle PWM signal to standstill motor. It turns a little bit and then stacks. Also it achieves current limit very soon and stay.
So I am wondering to know is it possible to assign a very high duty cycle to bldc motor directly ? or I should increase duty cycle gradually ?
Thanks in advance.
