摘要： A three phase linear motor system includes a forcer having three pole pairs, which are moveable relative to a platen. The pole pairs are arranged to oppose associated teeth of the platen. The platen teeth are spaced apart from each other in a travel direction according to a predefined tooth pitch. Each of the pole pairs includes a set of teeth that extend from magnetically coupled poles toward the platen. The set of teeth of one of the pole pairs is spaced from the sets of teeth for the other two poles by distances functionally related to about 120 degrees and 240 degrees, respectively, of the tooth pitch.

摘要： An improved linear motor utilizes two circuits, rather that one circuit and an opposed plate, to gain efficiency. The powered circuit is a flat conductive coil. The opposed segmented rail circuit is either a plurality of similar conductive coils that are shorted, or a plurality of ladders formed of opposed conductive bars connected by a plurality of spaced conductors. In each embodiment, the conductors are preferably cables formed from a plurality of intertwined insulated wires to carry current evenly.

摘要： A motor for driving a load, such as a tool or a workpiece, can be installed in a machine, for example an eccentric lathe. The motor has an output-drive section associated with the useful load, a reaction section which interacts with the drive section, and a base that rigidly supports the motor in the machine. The reaction section of conventional motors is typically rigidly attached to the machine, so that vibration can be introduced in the machine bed if a strong force is transmitted to or received from the load. According to the invention, these vibrations can be reduced or eliminated by mounting the reaction section on the base in such a way that any movement by the output-drive section can be compensated by a corresponding opposing movement of the reaction section. The inertia of the reaction section hence compensates the corresponding opposing forces in the event of sudden or strong acceleration of the load.

摘要： A linear actuator includes a supporting unit with a stopper, a linear output unit, a movable unit, a magnetic flux generating unit and a control unit. The movable unit is connected to a stopper of the outer pipe at one end of the outer movable unit and to the linear output unit at the other end. The magnetic flux generating unit generates first magnetic fluxes. The movable unit has elasticity, and expands or contracts based on action of the first magnetic fluxes and the elasticity. The linear output unit linearly moves in response to the expansion or contraction of the movable unit.

Thus, there is no need to secure the cover additionally by gluing etc and the cover can be easily replaced. The cover can be placed, preferably, as one piece upon the secondary member, which may be made of several secondary member elements, and carries a scale for controlling the position of the motor.
