Hi all

Big gap since my last visit and im here to try to understand the principle operation of this condensor fan motor?

Its not the norm setup inside and six windings and a flat surface stator..

Motor is a woods from a Trane ERTAB 212

It goes round, you could say that it is a circular linear motor.

Hitachi brought out a hifi turntable motor like that in the 80's. Said to give a smooth linear action with less flutter. They called it the Uni_torque.http://www.radiomuseum.org/r/hitachi_uni_torque_direct_drive_automatic_turntable_ps_58.html
