Application: Encoder device, drive device, stage device, and robot device (Patent ID: US20240100689A1)
The patent filed by Nikon Corp describes an encoder device that includes a position detection unit, a magnet with multiple polarities, and an electric signal generation unit based on a magnetosensitive part. The magnetosensitive part is positioned in a specific way relative to the magnet to generate an electric signal based on changes in the magnetic field associated with movement. The device is designed to detect rotational position information of a rotary shaft and generate pulsed electric power by rotation, with the option of using a battery for power supply.
The encoder device also includes features such as guiding magnetic field lines, generating large Barkhausen jump, and the ability to switch power supply from a battery based on the electric signal generated. The device can be used in various applications such as drive devices, stage devices, and robot devices for moving objects or arms. Overall, the patent outlines a unique encoder device design that efficiently detects position information and generates electric signals based on magnetic characteristics, with potential applications in different fields requiring precise movement control.
