Commentary
This is a full auto-player system that allows computer control of almost all operations when combined with the HCC-8 control center that allows wireless remote control.
The motor is equipped with a unitorque motor based on Lordi's proprietary technology.
The Unitorque Motor is a motor which obtained perfect circular motion from the principle. It consists of a doughnut-shaped rotor magnet magnetized with 8 poles and two sets of star-shaped flat coils offset by 22 ^ 5 degrees. The torque generated by these two coils and magnets is constant at any moment. This principle is called sin2Θ + cos2Θ = 1 ". The Uni-Torque Motor also adopts a simple structure that is brushless, slotless and coreless, and has significantly improved durability.
Equipped with full auto functions such as auto return and auto cut.
Equipped with an oil dump type arm lifter.
Howling countermeasure is taken by special insulator and vibration-proof tone arm.
Head shell can be replaced.
