Features of This Unit
Belt drive
We have introduced a drive system in which motor-derived
noise is attenuated via a belt and smooth rotation is achieved.
Circuit configuration
AC synchronous motor is driven by sine waves coming from
32-bit microprocessor, which are DA converted and amplified
by a high-power audio amplifier.
Stroboscope
This unit is equipped with a reflective view type LED stro-
boscope that is useful for adjusting the rotation speed in a
precise manner.
High torque motor
An AC synchronous motor with high torque is adopted to
achieve precise and quiet rotation.
Heavyweight platter
The platter weighs 5.0 kg, which is machined from aluminum
metal to improve accuracy.
Approximately 0.7 t·cm
2
of moment of inertia has been
achieved.
High rigidity main chassis
This unit uses an underslung vibration-damping structure ca-
pable of hanging internal main parts using machined alumi-
num plate with 15 mm in thickness as a base.
