Abstract	Experimental studies and theoretical modeling of high temperature superconductor (HTS) magnetic bulk applications are conducted and reported. The magnetic force density as a function of the magnet superconductor separation in the mirror image FEM 2D picture shows a strong dependency on the distance and PM mass. The behavior contrasts all attempts of generating high magnetic levitation forces with a minimum of material effort. An optimum configuration PM HTS coupler has been designed and built for a 300 mm wafer spin test apparatus. With rotational speeds up to 1500 rpm a safe operation and handling the imbalance of the wafer spin clutch by passing the resonance speed at 370 rpm is investigated. The smart rotor rotation is studied to drive a half-wave plate of a polarization apparatus to detect cosmic microwave radiation safely through resonances and imbalance effects.
