Abstract
A hall rotary transformer comprises a rotary transformer stator (), linear Hall components (), a PCB () and a permanent magnet magnetic ring (). A ring shape soft iron core () is installed on the PCB (). Plural grooves () are uniformly distributed inside the peripheral surface of the ring shape soft iron core () and have the same number as the linear Hall components (). Every linear Hall component () is installed in its corresponding groove () and soldered on the PCB (). The magnetic sensitive surface of each linear Hall component () is aligned with the magnetic pole surface of the permanent magnet magnetic ring () each other. A Hall rotation angle encoder is made of the Hall rotary transformer.
