Wilson Benesch writes: “A moment in time. A snap shot into the first full production of the new GMT System One Turntable motor chassis here at the Wilson Benesch factory. The motor chassis is machined from a solid 30kg / 66lbs aluminium billet to create the final motor chassis component which weighs 5kg / 11lbs.
The motor chassis forms the primary structural component and reference within the OMEGA Drive. The chassis is in turn fitted with a stator, a series of PCBs and 21x precision-wound coils, along with the platter. These housings on the underside of the motor chassis are machined in one operation which legislates for absolute precision and repeatable accuracy that is critical to the function and accuracy of each motor Wilson Benesch builds. The 0.01mm tolerance of our machining centres eliminates any potential discrepancies or variance in production that would affect the performance of the motor. By achieving such precision, we are able to establish harmonious synchronicity in the OMEGA Drive through the coils and surrounding NdFeB magnets. The result is optimal performance and accuracy.
The motor chassis component requires 6 hours of machining, split into two operations per chassis. No effort, nor compromise is spared. The OMEGA Drive is the world’s first and only, low torque, zero cogging, direct drive motor that has been developed from the ground up to deliver a new level of accuracy and performance in analogue replay.
