charge on force conducting areas 92 to move the mass toward its
reference position. The force on mass 36 is proportional to the
numerical product of the amount of charge deposited on plates 92
times the force electric field.
Hulsing discloses in Figure 2 a transducer having a rotor 60
suspended between magnetic structures 50, 55 by the attractive
forces caused by interaction of the magnetic field set up by the
stator magnets 44, 45 and the magnetic coils 52, 57. Coils 52, 57
are not
only used to control the axial position of the rotor 60 but are
also energizable to deactivate the magnetic suspension to cage the
rotor such that it is brought into contact with the stator 40.
