04. F (DEGJ Measured and simulated friction characteris­ tics of APS bearings. The cogging torque is caused by the interaction of permanent magnets with motor winding slots in the 24 pole gimbal torque motors. Figure 4 shows test measurements of the disturbance torque. The cogging torque was modeled with a fifth order Fourier series with a 24 Hz fundamental. 5 u Fic ■ ^ *W J N torrf^ - . 3 7 / * ov ΟΛ/ e O ea : r e y ö / j+icN Cogging torque for one torquer caused by inter­ action of permanent magnets in the gimbal torquer motor.

Was taken from Dahl(1968). This model did not match test results for the case of momentary reversals in direction and was modified using the results of 0sborne(1974) to obtain results better The e quations of motion for a two axis gimbal set were derived in closed form by taking advantage of the gimbals symmetric geomet ry and treating each gimbal as a rigid body. The equations describing the five 1 owest bending modes of the flexible hinged mast sans gimbals were obtained from finite element model of the struct Lire.
