ABSTRACT:
A magnetorheological fan coupling (10) having a fan-drive subassembly (12), an electromagnet subassembly (14), and a magnetic medium (16). The fan-drive subassembly (12) includes an output member (22) and an input member (20) rotatably mounted around the output member (22) with the magnetic medium (16) therebetween. The magnetic medium (16) has a shear stress that can be adjusted by a magnetic flux (24) for transferring torque between the input member (20) and the output member (22). The electromagnet subassembly (14) includes a stationary electromagnet coil (62) for adjusting the shear stress of the magnetic medium (16) and regulating a torque transferred between the input member (20) and the output member (22).
