An electromechanical machine having a stator and a rotor, the stator including at least one stator module of N toroid shaped electromagnets, the electromagnets arranged along an arc a predetermined distance apart defining a stator arc length. Each of the electromagnets has at least one gap. The rotor includes a disc adapted to pass through the at least one gap. The disc includes a plurality of permanent magnets spaced side by side about a periphery thereof and arranged so as to have alternating north-south polarities. The permanent magnets are sized and spaced such that within the stator arc length the ratio of permanent magnets to electromagnets is N+1 to N, where N is the number of electrical excitation phases applied to the electromagnets.

A contact device having a plurality of nominally coplanar first contact elements makes electrical contact with corresponding nominally coplanar second contact elements of an electronic device when the contact device and the electronic device are positioned so that the plane of the first contact elements is substantially parallel to the plane of the second contact elements and relative displacement of the devices is effected in a direction substantially perpendicular to the plane of the first contact elements and the plane of the second contact elements. The contact device comprises a stiff substrate having a major portion with fingers projecting therefrom in cantilever fashion, each finger having a proximal end at which it is connected to the major portion of the substrate and an opposite distal end and there being one or two contact elements on the distal end of each finger. It is necessary to effect relative displacement of the devices by a distance d from first touchdown to achieve last touchdown. The substrate is dimensioned such that relative displacement of the devices by a distance d from first touchdown generates a reaction force at each contact element of about 0.1*f&plusmn;0.1*f, and further relative displacement by a distance of about 75 microns or 5*d beyond last touchdown generates a reaction force at each contact element of about 0.9&plusmn;0.1*f.
