ABSTRACT:
An induction type positioning system which accurately stops a movable part without a contact and holds it in the stopped position without depending on the friction force of mechanical contact is disclosed. A primary core consisting of a main pole, an auxiliary pole, and a single phase AC magnetic field generation coil, and a conductive plate which moves relative to this primary core, generate a holding force for suppressing the relative movement between the primary core and the conductive plate by use of the eddy current which is induced on the conductive plate by the field generated by the main pole at the position where the conductive plate is placed on the auxiliary pole and simultaneously the edge of the conductive plate is placed on the main pole, and by use of the eddy current which is induced on the conductive plate by the field generated from the auxiliary pole. This structure provides a positioning system and simple braking mechanism such that positioning is not dependent on mechanical friction, thus, avoiding the heat, smell, smoke and noise associated with the conventional mechanical system.
For this reason, the system is particularly suited for installation within an office system.
