Applications in closed loop speed control
Source: InternetPublisher:子丑寅卯 Updated: 2021/08/30
Directly connecting a small number of external components to this circuit can realize open-loop or closed-loop speed control of a small-power three-phase brushless
DC motor. The closed-loop control shown in Figure 3 26 uses
an F/V converter to convert a Hall sensor signal into a speed feedback voltage , which is input from pin 5 , and the speed command voltage
is input from pin 6 for speed adjustment.
