ABSTRACT:
The device comprises an external inertia element which is fixed to a damping member which is coaxially fixed with respect to a shaft of a stepping motor, in such a way that it can rotate together therewith. The external inertia element comprises a metal mass in the form of an annulus of limited thickness. The damping member comprises a first circular flange to which the annulus is fixed, a second circular flange by means of which the device is fixed to the shaft and an annulus of elastomeric material connecting the two flanges. The materials and the dimensions of the device can be calculated, proportioned and pre-arranged in such a way that the device is compact but can stop oscillations of the stepping motor in a very short time. The device is particularly suited to damping the oscillations of a stepping motor which is used for example for positioning a printing member with respect to a print point or for positioning a recording head with respect to a magnetic disc.
