For electromechanical linear actuators used in laboratory instrumentation robotics, optical and laser equipment, or X-Y tables, fine resolution in the micron range and high accuracy may require the use of a fractional horsepower stepper motor linear actuator with a fine pitch lead screw. There are many variations in the electromechanical linear ...
A stepper motor, also known as step motor or stepping motor, [1] is a brushless DC electric motor that rotates in a series of small and discrete angular steps. [2] Stepper motors can be set to any given step position without needing a position sensor for feedback. The step position can be rapidly increased or decreased to create continuous ...
Bimorph cantilevers used in stepper or walk drive motor. Not to be confused with the similarly named electromagnetic stepper motor, these motors are similar to the inchworm motor, however, the piezoelectric elements can be bimorph actuators which bend to feed the slider rather than using a separate expanding and contracting element. [4]
A linear motor is an electric motor that has had its stator and rotor "unrolled", thus, instead of producing a torque , it produces a linear force along its length. However, linear motors are not necessarily straight. Characteristically, a linear motor's active section has ends, whereas more conventional motors are arranged as a continuous loop.
In 1973, inventors Hi D Chai and Joseph P Pawletko from International Business Machines Corp patent a "Variable reluctance linear stepper motor". Then a linear stepper motor of the variable reluctance type was for serial printer applications. In 1977 J.W. Finch researcher on the Linear Vernier Reluctance Stepper Motor to replace a mechanical ...

Multiple actuators are mechanically connected to the back of the input surface. The actuators are distributed along the surface, each at a separate contact location, to provide localized haptic feedback to the user. Piezoelectricity is used by actuators to convert the physically-induced vibration or the input displacement into an electrical signal.
PLECS (Piecewise Linear Electrical Circuit Simulation) is a software tool for system-level simulations of electrical circuits developed by Plexim. [1] It is especially designed for power electronics but can be used for any electrical network.
