The speed control circuit is a special design, dedicated to the “Langer” motor. This circuit works completely analog. That means we compare an analog signal for speed feedback with an analog speed reference. Therefore, the output signal to the motor is also analog. In combination with a correctly designed platter, the signal to the motor is a simple flat line. During playback, the motor acts just as a precision bearing plus a little energy for the friction losses. Only during start mode or at higher break forces, it increases the drive current accordingly to the needed level. The result is a comfortable settling time for platter speed and absolutely low wow and flutter values during your listening audience.
