Noise on the hall signal

It is custom board i am finding noise on the hall signals when the motor is running. When i run it at 48V using power supply it runs but observing noise on the hall waveforms



I am separating the power ground and digital ground using the Ferrite bead BLM21BB201SN1D but i do not observe any improvement, i am using a hall filter of around 2KHz cut off frequency, resistance is 10k and Capacitance is 8.2nF.

When i connect to 60V battery and try to run it gives hall fault due to noise. Is Schmitt trigger is the only option? Please help.

What hall sensor are you using, and have you tried swapping in another to rule out a defective part ? I just recently went through this whole signal integrity exercise only to discover the sensor was no good, fixed by simple replacement
