Speed Servo Control
A set of control IC models : LHA31015
SSOP20 is Hall Sensor BLDC Motor servo control IC
SSOP16 is close-loop control IC
L X W : 120mm X 72mm
The phase of 120 degree angle Hall-effect sensor
Set by resistor divider :
1.SST , Soft start function ( or VR knob adjustment )
2.IDT , Initial duty set function
3.STP , Soft stop function
External 20K band switch to control motor speed
When there is no external band switch, the motor maintains a certain low speed after power-on
DC 16V external control system
Speed output signal (FG)
Alarm LED,Breakdown caution function
