Title:
MAGNETIC ENCODER
Document Type and Number:
WIPO Patent Application WO/2024/057621
Kind Code:
A1
Abstract:
This magnetic encoder has an annular support member made of a steel plate, and an annular resin magnet fixed to the annular support member, wherein: the annular resin magnet includes a polyamide resin binder, magnetic powder, and glass fiber; and the polyamide resin binder is a polycondensate of diamine and biomass-derived sebacic acid. The magnetic encoder has good magnetic properties, heat resistance, and calcium chloride resistance, and can reduce the burden on the natural environment compared to conventional magnetic encoders.
