とした差動トランス。 It consists of a shaft with a screw, a magnetic core with a screw on the inside and a guide section on the outside, and a bobbin with a guide section on the inside and a winding wound on the outside. When it is transmitted to the magnetic core by the screw of the magnetic core and the screw of the magnetic core, the magnetic core makes a linear motion by the guide part of the magnetic core and the guide part of the bobbin, so that it is wound around the bobbin. A differential transformer that detects rotational displacement by detecting changes in coil impedance.
