MGI 陀螺仪

The Gyroscope, "MGI", allows the experimental demonstration of the different rotation modes of a gyroscope and the moments generated by the gyroscopic effect.

The rotor of the electric motor (rotating motor) shares a horizontally supported shaft (torque arm) with a rotor disc about its own axis. The rotor disc is mounted together with its motor as a yoke and forms the gyroscope. A second electrical motor (precession motor) turns a turntable under the gyroscope, causing precession about a vertical axis. The speed of both motors are electronically regulated and independently controlled. The rotational velocity of the rotating motor and the precession motor can be visualized in digital displays (in the electronic console).

The gyroscopic moment can be preselected by positioning a counterweight with retaining screws at different radii.

Additional weights can be attached to the end of the torque arm to balance the gyroscopic couple produced when the rotor disc is spinning and the gyroscope is being rotated (precessed) about the vertical axis.

A transparent protective cover provides protection against rotating parts and enables different experiments to be observed. Opening this cover automatically stops the two electrical motors.
