The sensor tracks the magnetic field direction only in the X-Y chip plane, with reasonable placement tolerances of the IC, especially for the operating distance to the diametrical magnet. Therefore, an axial play of the motor shaft can be tolerated without significant impact on angular accuracy.
The sensor signal is resolved by a high-resolution interpolator, featuring resolution-enhancing digital filtering and automatic signal error correction. The device ensures minimal angular error, excellent position jitter even at low speeds, and unmatched position noise at standstill.
