A driving apparatus includes a holding member configured to hold an object to be driven, a support member configured to support the holding member via an elastic member, a plurality of actuators configured to drive the holding member holding the object, and a constrainer configured to constrain, in a non-contact manner, a position of the holding member with respect to the support member in anon-driving direction different from a drivable direction which is a direction in which the holding member can be driven by the plurality of actuators.

A linear motion control device for use in a linear control system is presented. The linear motion control device includes a coil driver to drive a coil that, when driven, effects a linear movement by a motion device having a magnet. The linear motion control device also includes a magnetic field sensor to detect a magnetic field associated with the linear movement and an interface to connect an output of the magnetic field sensor and an input of the coil driver to an external controller. The interface includes a feedback loop to relate the magnetic field sensor output signal to the coil driver input.

Embodiments of the present disclosure include an actuator for steering mirrors with low magnetic hysteresis losses at high frequencies, with a fast step response, and without excessive heating of the steering mirror. Various embodiments of the actuator include two stators (a left stator and a right stator or an inner stator and an outer stator) and a rotor positioned between the stators. Each stator has a core assembly with one or more cores, two or more legs, and two or more faces positioned proximate to the rotor. The two or more legs are separated from one another by portions of the one or more coils. The rotor includes a core and a plurality of magnets, where each magnet has a face positioned proximate to the faces of one core assembly.

A liner motor based on radical magnetic tubes includes: a dynamicer (mover, QDZ) and a stator (STA), the structure of the stator (STA) is: a stator magnetic tube (SCG) is nested into the inner wall of a pure iron tube (DTG), the stator magnetic tube (SCG) provides a radial magnetic field, a stator tube (DZGD) is formed within the stator magnetic tube (SCG), the dynamicer can travel in the stator tube; the dynamicer iron core is a tube of a radial magnetic field and installed on a tubular coil skeleton, on which winding the dynamicer coil to form the dynamicer main body; the sliders (HDZ) are installed on both ends of the dynamicer main body load.

The invention relates to a handheld nail setting device comprising highly dynamic electromagnetic drive in the manner of a Thomson coil with soft-magnetic frame, comprising a first excitation coil (30) whose winding height is greater than its length, which hence is flat; a soft-magnetic frame in which the first excitation coil is arranged and against which it abuts, and which in in the manner of a pot magnet constitutes an open magnetic circuit which includes an outer region, a bottom and an inner region, and which is open on its end face, wherein the first excitation coil at least partly encloses the inner part of the frame; a short circuit armature preferably formed hollow cylindrical at least on its side facing the first excitation coil, which is movably mounted along an axis and which in its stroke starting position dips into the end-face opening of the frame and thereby at least partly encloses the inner part of the frame, wherein the frame entirely or predominantly is formed of a soft-magnetic composite material or one or more sheet stacks, which has a saturation flux density of at least 1.5 T and an effective specific electrical conductivity of not more than 10.sup.6 S/m, and the first excitation coil and/or the frame include at least one means for strain relief, in particular in the form of an enclosure in order to at least partly absorb at least the radial forces occurring on the first excitation coil during an actuating operation vertically to the direction of movement, and wherein the Lorentz force acting on the short circuit armature is used to perform work.
