<p>COMBINED LINEAR MOTOR AND SIDE MOUNTED OUTBOARD CARRIAGE A linear motor and side mounted outboard carriage combination. There is an elongate magnetic core having a longitudinal motion axis. An armature is associated with the core and can move along the axis. Carriage ways are secured on opposite sides of the core. A carriage assembly is mounted on the ways and connected to the armature for movement with the carriage along the axis. Portions of the carriage assembly are mounted on the opposite sides of the core and are so arranged that the center of gravity of the carriage assembly and all elements connected to it is approximately aligned with the center of force of the core. The invention is useful in all circumstances where prior linear motors and carriage combinations are useful but is of particular value where high precision of movement is required, for example in a computer disc drive. The combination of the invention has its center of gravity in line with the center of force provided by the motor and this reduces structural resonance. Further the result of a crash against a stop is not as serious as in prior art combinations of carriage and motor.</p> |
