4. Specification (turntable)
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.
Speeds 33 1/3, 45 & 78 rpm
