Source: Ali Bazzi, Department of Electrical Engineering, University of Connecticut, Storrs, CT. The objectives of this experiment are to find the equivalent circuit parameters of a three-phase induction motor using the per-phase equivalent circuit and tests similar to those used in transformer characterization. In electrical engineering, an equivalent circuit (or theoretical circuit) can be determined for a given system. The equivalent circuit retains all characteristics of the original system,...

Source: Ali Bazzi, Department of Electrical Engineering, University of Connecticut, Storrs, CT. The DC machine operates with DC currents and voltages as opposed to an AC machine, which requires AC currents and voltages. DC machines were the first to be invented and utilize two magnetic fields that are controlled by DC currents. The same machine can be easily reconfigured to be a motor or generator if appropriate field excitation is available, since the DC machine has two fields termed field...

The accuracy and sensitivity of protein determination by the rapid and convenient Bradford assay is compromised by intrinsic nonlinearity. We show a simple linearization procedure that greatly increases the accuracy, improves the sensitivity of the assay about 10-fold, and significantly reduces interference by detergents.

Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California One principle of brain organization is the topographic mapping of information. Especially in sensory and motor cortices, adjacent regions of the brain tend to represent information from adjacent parts of the body, resulting in maps of the body expressed on the surface of the brain. The primary sensory and motor maps in the brain surround a prominent sulcus known as the central sulcus. The cortex...

The Drosophila larva is a powerful model system to study neural control of behavior. This publication describes the use of linear agarose channels to elicit sustained bouts of linear crawling and methods to quantify the dynamics of larval structures during repetitive crawling behavior.
FAQs
The motor supplies rotational drive, while a lead screw or ball screw converts that drive into linear travel. Guideways constrain the payload to a single axis, reducing unwanted movement during positioning. An encoder can report position for controlled motion, while limit switches help manage travel boundaries. Together, these elements support programmed movement with controlled distance, speed, and repeatability.
An encoder provides position feedback, allowing the control system to monitor where the stage is along its travel. A limit switch serves a different purpose by providing travel control at defined limits. Using these components appropriately helps distinguish routine position management from boundary detection, which is important when a stage operates within an automated inspection, optical, or laboratory setup.
Engineers should match the stage to the required payload movement, travel distance, speed, and repeatability. The mechanical transmission affects how motor rotation produces linear displacement, while the guideways maintain the intended axis of motion. Feedback or limit components should also suit the control objective. Considering these requirements together helps achieve accurate positioning and reliable automated operation.
Programmable speed and distance allow a stage to execute repeatable motion rather than relying on manual positioning. Engineers can specify how far a payload moves and how quickly that movement occurs, supporting consistent sequences in inspection, alignment, processing, and instrumentation. This control can improve positioning accuracy and throughput when the same motion must be performed repeatedly.
Begin by defining the payload movement, required travel distance, speed, and repeatability. Select a compatible transmission and guideway arrangement, then determine whether position feedback or travel-limit control is needed. The stage can subsequently be incorporated into a programmable machine, instrument, or robotic system, where its controlled linear motion supports the intended automated sequence.
Applications include automated inspection, optical alignment, semiconductor processing, laboratory instrumentation, and robotic systems. In each setting, the stage provides controlled movement along a linear axis, allowing a payload or instrument to reach programmed positions. This makes the technology useful wherever repeatable positioning, improved throughput, or coordinated motion is required in an experimental or production workflow.
