Just to clarify for Brad, the platters on ANY direct drive are mechanically fastened directly to or are a part of the motor, hence the term "direct drive". In many cases, the platter is an integral part of the motor, forming either part of the stator or part of the rotor. In order for the platter to turn, the motor must contact the platter either indirectly (belt or wheel drive) or directly by being mechanically fastened or being an integral part of the motor (direct drive).
Also, ALL electric motors are electro-magnetically driven and ALL electric motors make noise. The trick is to minimize the noise as much as possible. Glass, acrylic or MDF dampen noise far more effectively than a thin piece of aluminum.
