ber of coil turns is 500. The electromagnetic disk was assembled to the housing
with a specic gap fully lled with the MR uid (MRF-132DG) from the Lord
Corporation. Figure 9.23(b) shows the assembled view of the manufactured
MR haptic cue device, which is connected with a commercial accelerator pedal.
Table9.1 presents design parameters of the manufactured MR haptic cue device.
Figure9.24 presents the produced torque characteristics of the manufac-
