How to detect the rotor position reliably in case of locked rotor or very low speed

hi

 

 I hope that my motor driver can still work at a very low speed or locked rotor. The current scheme is NXP's official sensorless and square wave drive scheme. The back EMF generator cannot work at a low speed. Is there any other scheme for reference? Thank you.
