Vertere RG-1 Reference Motor Drive
The motor is the heart of a record player. It drives the record at a constant speed, which is essential for accurate sound reproduction. Any noise or fluctuation in the motor's speed will degrade the quality of the sound. Detail, dynamics, timbre, timing and musicality will suffer as a result. The RG-1 Reference Motor Drive is a high-performance motor that delivers smooth, accurate rotation, resulting in music that is incredibly close to the original master.

Vertere RG-1 Reference Motor Drive
RG-1 Reference Record Player utilises a synchronous motor for its drive. Synchronous motors, unlike DC motors, can only run at one constant speed as they effectively ‘lock’ onto the frequency of their drive signal. A well-designed motor drive can ensure a constant rotational speed
The RG-1 Motor Drive, under development for over two years, was envisioned to match the performance of the Reference Tonearm/RG-1 record player combination and realise their full performance potential.
Another requirement was to provide fine steps in speed adjustment for those records that required small speed correction. These speed errors can occur during the cutting process or could even exist on the tape. To achieve this, RG-1 motor drive utilises a microprocessor and generates the exact frequencies that are required to drive the motor at the desired speed steps.
After the microprocessor, a high-quality internal D to A Converter then converts the frequencies to analogue Sine & Cosine waves that are vital for driving the motor. The Sine & Cosine waves are subsequently amplified to the required levels using 20W audio amplifiers that then drive the motor. The entire circuit and process are designed to ensure absolute motor speed stability without unwanted noise and distortion.
Fully programmable, RG-1 Motor Drive allows any necessary adjustment in order to achieve all speed steps required making it totally future proof. There are no less than three dedicated toroidal transformers to provide the power required for the output amplifiers and the different sections of the internal circuitry.
Three fully regulated and decoupled power supply rails power the microprocessor, the DAC and all the operating circuits. The microprocessor is programmable via a RJ11 on-board socket and its entire circuit is fully isolated using a solid copper shield can. The highest quality components are used to ensure the theoretical design is implemented fully and the performance optimised.
There are 7-speed adjustments via the front rotary knob allowing fine and exact ‘fixed’ speed selection of +/- 0.25%, 0.50%, 0.75%, 1.00%, 1.50%, 2.00% and 3.00% about the original 33 & 45 rpm.
There are two switches for 33/45 selection and Sleep/Operation modes. The entire motherboard is mounted on an aluminium chassis and housed in a solid machined aluminium alloy cover.
Fine tuning of the residual motor noise is easily carried out from the underside of the unit.
