“A wide hole was milled into the bottom side of the platter, where a large TMD (Transrotor Magnet Drive) bearing fits. Jochen Räke once talked about development of this bearing in an interview that he gave our magazine. It is a bearing with a magnetic clutch, consisting of three main parts – a spindle with a base, a low pulley to which torque is transferred from the motor and the upper, high part, which is actually a sub-platter. Around the spindle with a ceramic ball there is a milled space for oil.

The upper part of the bearing consists of two parts, separated from each other by a magnetic field generated by many small neodymium magnets. The idea is to separate these two elements from each other, and thus to reduce the vibrations transmitted by the drive belt from the motor. The belt is placed over the lower part and the platter rests on the top one.

Motor | Alto TMD is a design with a separate motor, placed next to the turntable. One can use such solution only in mass-loaders. Therefore, the motor features a solid, heavy cylinder housing. A small, aluminum spindle is mounted on the motor axis, and puts a rubber drive belt over it. The motor is placed on the side – Transrotor suggests placing it on the left side, but I would suggest to start your test by placing it on the line connecting the motor column and the platter’s axis.”
