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.
