Natural Sound

[Bruno Rivademar]

I think the Falcon controls the speed by hunting and correcting. The AS2000 has no correction. It relies on the 150 lb platter mass, very low bearing friction, and high quality motor for speed stability. The motor spins at a constant speed based on voltage. It does not need the Folcan for correction.

It is just a different approach to speed stability and it affects the sound.

Is it an AC synchronous motor?

Is it an AC synchronous motor?

As far as I know, the Papst hskz 32 80 440d three phase motor. Peter was mistaken in his answer , the speed is controlled by frequency, not voltage. Voltage is adjusted for best torque with minimal noise.

Turntables with synchronous motors can be extremely speed accurate - the user adjusts the frequency of the controller at start up for desired speed.

Some TechDas turntables do it automatically at start up using the platter tachometer and from there on, the frequency is locked - no more feedback.

Some people prefer using these motors with three phase controllers, other prefer single phase with a de-phasing capacitor.
