Hello,
we use a SBL2360T to drive a BLDC-wheel-hub-motor. The motor is with SIN/COS-encoder (AS5115) and has 11 pole-pairs.
In general: when using another direct-drive-BLDC with Hall-sensors, the driving works in principle.
When changing to BLDC-drive, we are facing problems with SIN/COS-encoder (even without driving the BLDC with power).
The signal-detection seems very noise, the number of pole-pairs multiplies the noise, in fact we have the overal value-range in electrical-angle even when the motor is not turning.
This behavior does not change, when we use an arbitrary-signal-generator to generate the SIN/COS-signal
Is there any way to filter the signal internally? Or do you see any other possibilites? Or do you have any ideas?
See attached some screenshots.
=> No current, manual turning, 1 pole-pair configured (config is wrong, but only to see the electrical-/sensor-signal)
=> No current, manual turning, 11 pole-pairs configured
Thanks and best regards,
Josef
