ABSTRACT:
An electromechanical driving device comprising a permanent magnet rotor mounted for rotation on a non-magnetic support plate, and a wheel train mounted on the support plate and driven by the rotor. A coreless field coil is mounted on the support plate and positioned to drive the rotor and thereby drive the wheel train when the coreless field coil is energized. The coreless coil is wound on a coil bobbin having an axial bore. The support plate includes a projecting portion dimensioned to fit within the axial bore of the bobbin to support the bobbin and thereby mount the same on the support plate.
