Hello

I am using

''

ACIM

and

BLDC

motor control

firmware

library

V1.0''

BLDC

motor

and

a

hall

sensor.

In closed

loop

speed when

the motor

decelerates

the system reduces the

duty cycle.

Finally,

there is no

PWM

signal

and the motor

slows down

freely.

Is

the library

prepared

to stop

the motor

in closed loop (

Four-Quadrant)?

Best regards

In the STM8 BLDC libary is implemented an active brake strategy injecting a DC current in the motor. It is done imposing a prefedined power switch configuration like the one of the alignment phase with a modulated PWM and can be enabled using the GUI.
