Unfortunately, the assumption is wrong. The current direction is changing from motor to generator operation. The shown circuit isn't able to "brake" for this reason. You would need a full bridge, that handles both current polarities.while changing from motoring to generating cannot reverse due to its inductive nature and continues to flow in the same direction
I understand, that you are suggesting a control algorithm. I guess, it can work. If it's good depends on the operation conditions of the motor, particularly the disturbing influences. If constant speed is an objective, most people would start with a PI speed controller. Because EMF is directly linked with speed, the purpose of using an separate estimated EMF in the control algorithm isn't obvious to me.is this aproach correct
Both circuits can be found.is the motor coils UVW conected as star or delta ?
No.but isnot this an error ?
