Hello,

I have a HBL1650. I would like to know the its accuracy for measuring the velocity of a three-phase motor with the three Hall sensor signal A, B, C, which is the HallSpeedRPM parameter in Roborun.

Thanks in advance.

It should be pretty accurate as it gathers that data by looking at the phase transitions.

If you are looking for accuracy to be spot on, then we suggest you go with a high resolution encoder instead.

Thank a lot.

How about the accuracy of MotorAmps that HBL1650 measure? Can you tell me?

See page 28 and 29 of the user manual that explains how motor amps is calculated.
