This paper describes the switching characteristics of torque transmission and their improvement by modifying a rotating disk and case in a magnetic fluid coupling, as was discussed in our previous report. Whenever a magnetic field is applied to a fluid coupling, the magnetic fluid shifts to the outer area of the rotating disk, and a torque is transmitted via the viscous friction of the magnetic fluid between the disk and the case. In order to enhance rapid and smooth movement of the magnetic fluid, slits were cut in the rotating disk. A channel for magnetic fluid was cut at the bottom of a case to cancel the output torque under a non-magnetic field. As a result of these modifications, a large torque difference was obtained whether a magnetic held is applied or not. The response of the output torque was also improved whether the input signal is turned on or off.
