For example, one of ams’ recently released magnetic angle position sensors, the AS5147P, includes a patented feature that offloads motor controllers from performing a task that they would ...

It has 1024-position angular resolution with the data output serially as a 10-bit code. It suits harsh environments and, because it uses a ball bearing, can operate up to 10,000 rpm.

Part 2 of this article will describe a possible solution that eliminates the errors due to imprecise information from the Hall sensors in the measurements of the rotor angular position while improving ...
