RE: any difference between magnetic drive & direct drive ?

Posted by Tedmc on March 24, 2010 at 12:22:03:
DIRECT DRIVE: Cheap drive system utilizing 7 magnets/poles mounted closely to the spindle.These were popular with cheap Japanese TT's. The worst place to mount a drive system is close to the spindle bearing.This creates a 7 pole motor generating energy directly into the chassis/platter in close proximity to the bearing/spindle.
MAGNETIC DRIVE: Elegant drive system as used by Grand Prix/others. Utilizes 192 or more magnets/poles at the outer rim of the platter (allows computer control of electricity to the drive system) Places the motor as far away from the critical bearing/spindle as possible.
