AlNiCo Ring Shaped Magnet for Speedometer

Speedometer magnet for motorcycle can be regarded as one of the biggest user of Alnico magnet over the past decades, Alnico magnet is fixed on the drive shaft and rotate with the shaft. A metallic cup cover Alnico magnet which acts as coils, and there exists a certain gap between Alnico magnet and cup. Low end of speedometer’s needle fix together with metallic cup while connect with a hair spring. Hair spring will ensure help needle swing steady and reset timely.
