|To reduce the pressure of the axle, which carries the mass of the moving parts, on the bearing point, Sheffield Hallam University, under the leadership of Dr. Faris Al-Naemi, developed a magnetic counterforce design using two powerful N30H neodymium iron boron magnets. This minimizes bearing wear while still providing sufficient force for efficient energy transfer from the platter to the FrACTal motor chassis.
The OMEGA Drive motor is driven by the ALPHA Drive, which Dr. Carl Broomfield and Neil Broomfield of CAAS Audio developed in parallel. For the reasons mentioned above, it only needs to deliver a low torque. To overcome the considerable air gap between the stator and rotor in the OMEGA drive during the start-up phase, an integrated microprocessor provides a special starting algorithm. The ALPHA Drive then accelerates the motor until it reaches synchronisation. A further microprocessor in the control electronics then maintains a constant speed. The electronics generate three pure sine waves based on the time base of the integrated 11.2896 MHz quartz crystal, which are processed by three discrete, linear Class A amplifiers. The result is three low-distortion, high-quality sine waves, each with 1.2 amps: one for driving seven of the 21 coils. Together with the high inertia of the turntable due to the externally inserted stainless-steel weights, the synchronous motor guarantees the extremely high speed stability of the OMEGA Drive.

Even though the Continuum Caliburn with Cobra and Castellon cartridges was in my listening room 18 years ago, and the Techdas Air Force One with the Graham Phantom Elite tonearm and the Techdas TDCO1 cartridge, which even then carried a six-figure price tag, was in my listening room 12 years ago, I am quite sure that no other turntable has had so many technical solutions questioned and so often re-evaluated as the combination of the OMEGA Drive motor and the ALPHA Drive control electronics.
