MA710 - problem with interference magnetic field from stator on high current

Motor Drivers/Sensors

Hi,

we have some issues with sensor MA710. We use it to control BLDC motors Ri-70, and R-I80 from TMOTOR . We are usung STM Motor Control SDK as BLDC controller software…

Motor works well on low current, but on higher current we experienced some troubles. After few movements in higher current, encoder is unalighment to motor phases, and stops rotating. Reset of microcontroller is needed.

I looks like megnetic field from stator intererencing with magnetic field from rotor magnets.

What we can do to fix it?

Best regards

Hello Łukasz Łęcki,

Have you checked the placement of your sensor? MPS has a tool that can aid this placement: Magnetic Simulation Tool

Thank you,
