5 use cases

FDB motors (fluid dynamic bearing motors)

As next-generation devices evolve, drive motors are required to deliver superior quietness and precision. FDB (fluid dynamic bearing) motors solve these challenges, which are difficult to overcome with conventional ball bearings. By levitating the shaft with oil pressure to achieve completely non-contact rotation, they maintain low noise and high precision over the long term.
