Abstract:
A magnetic slip clutch comprising:a frame having a rotational support;a driving member mounted on the rotational support;magnetic field, driving elements mounted on the driving member and comprising a series of coils to be energized for creating magnetic fields;a driven member mounted for rotation on the rotational support;magnetic field, driven elements separated by an air gap from the series of coils and comprising magnetizable elements without coils which become part of the magnetic fields being generated across the air gap with energization of the series of coils on the driving elements, the magnetizable elements without coils being mounted on the driven member to be magnetically coupled to and driven by the magnetic field, driving elements to rotate the driven member; andan electrical control circuit connected to supply-modulated electrical power to modulate the energization of the coils and thereby the magnetic field being generated by the magnetic field, driving elements and thereby varying the torque transfer between the driving member and the driven member between substantially no torque transfer to full torque transfer.
