The result? Incredibly stable platter rotation, exceptional signal-to-noise ratio, and high rotational accuracy. The SL-5OC is equipped with the same 12-pole, 9-coil, three-phase brushless DC motor used in the SL-1500C and SL-1200MK7 Turntables. So in essence, you're getting the same high rotational accuracy as the higher-end models at a lower price. Seems like a no-brainer to me. For reference, other companies' affordable direct drive turntables typically use an 8-pole, 4-coil, 2-phase motor with a startup time of 1.76 seconds and a wow and flutter of 0.08%. The SL-50C achieves a startup of over half that speed at 0.7 seconds, with a wow and flutter rated at 0.025%–specs that put it in the same league as some of the best turntables in its class.

Additional technology includes digital motor control, which enables precise detection and correction for even more accurate and stable rotation. The system achieves accurate rotational speed detection by increasing the FG coil pattern density, which improves detection accuracy and allows precision measurement of platter rotation for more stable speed control. The turntable maintains stable motor drive current through unit calibration and digital correction. During production, the drive circuit and motor reference voltage are measured, and tolerances in components and magnetic circuits are automatically corrected, enabling highly accurate rotation. And lastly, a microcontroller-based control generates clean sine waves for motor drive, which provides smoother and more stable rotation compared to previous analog models.
