Permanent Field Magnets Of Synchronous Machinery

Abstract
Improved electromechanical drive, essentially characterized in that the adjustable power counter torque is constituted by a permanent magnet located in a cavity of the support base of the assembly of elements of the device, whose magnet is kept applied against the core, said magnet being susceptible to be driven in rotation to obtain the proper orientation of its polarity with respect to the polarity of the coil.
