Hi all!
i am using EVAL-M1-05F804
with dave and Micrium.
I have 2 Brushless Sensorless 2pole motor. ~20watt each motor (li-ion battery powered)
Motor is running quite well, even at low rpm.
My application is a robotic mower and i have 2 wheels to control (with gearbox reduction).
my questions are:
1- if i slow down the wheel, motor control give more torque to mantain constant rpm (good) BUT if i make the wheel spinning faster than set speed (like if my mower is going down in a slope), motor control doesn't brake/slow down the wheel speed..... In my application this is unacceptable!
i am doing something wrong or braking control is missing? i have a battery pack to store energy but also dissipating it is ok.
2- if i switch to hall sensor brushless motor, will i have speed control even if wheel is spinning faster than speed set?
3- if while motor is running i disconnect it, infineon motor control think that motor is still running!!! O_o is avayable a stall detection somwhere or i have to make it by myself?
Any suggestions?

hello? no one knows the answer?
seems like infineon doesn't know how it's own motor control works.....
