Frequently Asked Questions
What angular measurement range and resolution does the Honeywell HMC1512 achieve in a rotary position system?
The HMC1512 provides full 360-degree angular measurement using its dual magnetoresistive bridge outputs, with angular resolution below 0.1 degrees achievable through arctangent computation of the sine and cosine bridge voltages. This resolution level is sufficient for servo motor commutation and precision shaft positioning applications requiring better than 10-bit angular accuracy.
How does the dual Wheatstone bridge output of the HMC1512 allow unambiguous 360-degree angle sensing compared to a single-bridge sensor?
The HMC1512 outputs two bridge signals 90 degrees apart (sine and cosine), which when processed with an arctangent function cover all 4 quadrants of a full 360-degree rotation without ambiguity. A single-bridge magnetoresistive sensor provides only 180-degree periodicity, requiring additional processing or mechanical quadrature to distinguish the full rotation, while the HMC1512's dual output solves this in a single 8-pin SOIC device.
What supply voltage and temperature range does the HMC1512 support for industrial and automotive applications?
The HMC1512 operates from a single 5 V supply voltage and is rated for a temperature range of -40°C to +150°C, making it compatible with automotive underhood environments and industrial high-temperature installations. The wide temperature range ensures stable magnetoresistive bridge output over the full operating conditions without requiring bridge output recalibration.
In which motor control topologies does the HMC1512 replace a traditional optical encoder or Hall-effect sensor array?
The HMC1512 is a drop-in contactless replacement for 3-Hall-sensor arrays in brushless DC and PMSM motor commutation, since its sine and cosine outputs provide the rotor angle needed by field-oriented control (FOC) algorithms at all 6 commutation sectors. Unlike optical encoders that require a mechanical slot disk, the HMC1512 mounts over a diametrically magnetized magnet within a 5 mm air gap and tolerates vibration above 50 g.
