The SME Model 10 Precision Turntable is built to exacting engineering standards providing reliability and freedom from critical adjustments. Build integrity,
sophisticated electronics and vibration free moving parts allow the full capabilities of any sound system to be fully explored.

The turntable is driven by a 3-phase, 6 pulse, inductance motor, with 8 pole Neodymium magnets and 3 integrated Hall position sensors.
The electronic controller uses a high performance microcomputer, optimised for motor control. The Hall position sensors on the motor provide accurate feedback to the micro controller allowing very accurate and stable speed control, including 33 1/3, 45 and 78 rpm. The reference oscillator is a 10MHz quartz crystal, which is multiplied by 4 to produce an internal microprocessor clock speed of 40MHz.
The driver stage has CMOS buffers/MOSFET drivers with 1.2 Amp peak drive capability.
The power output stage is six high power complimentary Mosfets in a 3 Phase Bridge Driver configuration.
Closed loop speed control is implemented using a pseudo sine wave commutation sequence and a proportional-plus-integral (PI) algorithm.
The design incorporates a 4 layer surface mount technology pcb with on-board user adjustable speed variation control.
