One advantage of the gear drive turntable is the ability to locate the motor
far from the pickup. A 30' teleflex cable is optimal for the purpose.
Otherwise, remoting the motor a sufficient distance requires drilling a hole
in the floor. This can result in difficult relations for apartment tenants.

It's completely unnecessary. A good AC motor built with a nonmagnetic
armature shaft will be undetectable with any known cartridge from even
one foot.
