摘要： A cup shaped base 12 and a cap 13 are coupled, therein a coil spring 14 is accommodated to form a holder 11, and the holder is interposed between the bearing 3 of a rotor shaft 4 and a sleeve 5. Different from being directly mounted on the rotor shaft, since the base 12 is provisionally held on the rotor shaft, the operation efficiency at the time of assembling the motor is outstandingly increased.

摘要： An inertia damper has a mounting base (10) to be mounted on a rotary shaft (40) and an inertia weight component (20) which is coupled to the mounting base through a vibration absorbing layer so the vibration absorbing layer being made of a gel material with a penetration value of approximately 50 to 200. The inertia weight component is adhered to one surface of the vibration absorbing layer and the other surface of the vibration absorbing layer is adhered to the mounting base of the rotary shaft. A vibration wave generated at the rotary shaft side is dispersedly absorbed by deformation of gel material which forms the vibration absorbing layer and a vibratory component can be removed from a braking motion.

摘要： The device comprises an external inertia element (14) which is fixed to a damping member (16) which is coaxially fixed with respect to a shaft (12) of a stepping motor (13), in such a way that it can rotate together therewith. The external inertia element (14) comprises a metal mass in the form of an annulus of limited thickness. The damping member (16) comprises a first circular flange (17) to which the annulus (14) is fixed, a second circular flange (19) by means of which the device is fixed to the shaft (12), and an annulus (18) 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 (13) 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.

摘要： To increase an operational precision of a stepping motor, a brake plate is fixed to a rotary shaft and limited in a rotary direction. The brake plate is pressed against a brake base with a conical coiled spring so as to limit the rotation of the rotary shaft by using a frictional resistance as a brake torque generated in contact surfaces of both components. Since a constant brake torque is stably generated in the rotary shaft, it is possible to suppress the offset of the rotary shaft and to increase the operational precision of the stepping motor when the magnetization current of the stepping motor is cut in case that the stepping motor is driven by methods such as a one/two phase magnetization and a micro-step control.
