TEACHING DEVICE FOR DEMONSTRATIONS

摘要

The invention relates to a teaching device for demonstrations, meant to be employed in teaching the operating principle of electric vibration motors operating at industrial frequency. According to the invention, the device comprises a rotor (2) provided with a flywheel (3) laterally actuated by an electromagnetic vibration motor (1) supplied at industrial frequency, where the actuation angle can be changed by means of a worm-gear operating hoist (6) and the vibration motor (1) can be moved in the axial plane by means of a micrometric screw mechanism (5), while the rotor (2) can be moved in the vertical plane by means of another micrometric screw (7) so that, by the change of position of the two elements, all the concrete situations occurring in exploitation are simulated.
