The parts Timestep remove: unscreened switch mode power supply at top, plastic shield and arm.

 

Technics use newly designed pancake shaped drive coils, fed by power transistors driven from a VNQ6040S-E motor driver chip (2015) whose data sheet doesn’t make good bedtime reading. It is controlled by a Renesas R5F104 microprocessor (2015), part of the RL78 family billed as suitable for motor control – and of nightmarish complexity. Since both parts became available 2015 the motor is a very new design. Three Hall effect sensors, that sense the magnets in the rotor, provide positional feedback, as is common in BLDC motors. Rotational speed is sensed by a ‘hybrid encoder’ at the base of the platter bearing shaft. In all, the control electronics is vastly complex and Technic’s own motor parts and platter (rotor) very sophisticated. 

   It’s all a little awesome and very different to the outgoing SL-1210 Mk2. A look underneath at the die cast alloy frame that supports this new twin rotor platter and bearing assembly shows how different it is to the simpler base plate and single rotor motor of the SL-1210. Technics have enormously improved both strength and rigidity of the chassis and the plinth to avoid vibration and colouration. 

  Don’t miss our comprehensive review in the forthcoming September 2016 issue of the new Timestep-Technics EVOke with SME IV arm and external power supply to see what we think of this advanced new turntable.
