The driving (30) and driven (32) members of a magnetic drive (20) are separated by an enlarged gap (35) to provide clearance for a conduit (23) or other member. Flux pins (40) in the gap (35) maintain the torque transmitting capability of the drive (20). The spacing between two of the flux pins is increased to provide space for the conduit (23).

A magnetic drive coupling, comprising: (a) a rotatable driving magnetic member. (b) a driven magnetic member rotatable on substantially the same axis as said driving member, said driven magnetic member being located substantially adjacent said driving member for magnetically and drivingly coupling therewith, and said magnetic members being separated by a predetermined gap therebetween, (c) a plurality of flux pins located in said gap between said driving and driven magnetic members to reduce the reluctance of said gap, concentrate the magnetic flux in the interface between said members, reduce the torque diminishing effect of said gap, and enhance the torque transmitting capability of the coupling, and (d) means providing at least one clearance space between a circumferentially adjacent pair of said flux pins to provide a passageway in said gap for passing components therethrough.
