Nowadays, the learning methods (activities) and tools show more and more varieties with the developing of computer technology. Simulators have become the most important tools of computer-based education. We have a thought the technology being used in education more effectively will help improving the quality in this area. For this reason, a simulator (Electromechanical Systems Simulator) for the education of electric control techniques (sequence control) is developed for more easy learning, spreading the studies outside the laboratory (home or school), and increasing the ratio of active participation.
ESS simulator is designed to build and test various motor and control circuits. It will help you to try and learn how to build electromechanical systems. It can be used in laboratories to solve different design challenges, designed circuit drawings can be exported and used in educational reports and study materials. The simulator also might be used with an interactive drawing board in remote education or in class lessons.

Simscape Electrical (formerly SimPowerSystems and SimElectronics) provides component libraries for modeling and simulating electronic, mechatronic, and electrical power systems. It includes models of semiconductors, motors, and components for applications such as electromechanical actuation, smart grids, and renewable energy systems. You can use these components to evaluate analog circuit architectures, develop mechatronic systems with electric drives, and analyze the generation, conversion, transmission, and consumption of electrical power at the grid level.
Electrical engineers participate in all aspects of the analysis, design, testing, and integration of complex systems. For example, Sandia electrical engineers are applying advanced miniaturization packaging techniques to develop highly reliable, state-of-the-art electronic subsystems that can operate on ultralow power and withstand extreme environments. Other electrical engineers are conducting research and development for advanced micro-electromechanical systems that push the technology envelope for national-security applications. Still others are developing high-performing RF transmitters, receivers, and digital signal processors.
ELECTRIC-SYSTEMS offers a whole set of electric, electronic and electromechanical components. Moreover, the most commonly used control algorithms are included in the library so that the user can concentrate on the areas of design and performance.
Abstract:A field-programmable gate array (FPGA)-based digital solver for real-time electromechanical transient simulation is designed in this paper. The solving process for a device or sub-network in an electromechanical transient simulation is packaged into the orders in soft function solvers. The orders are reused by soft function solvers that are invoked by microprocessor cores. The data exchange between the microprocessor cores and soft function solvers is enhanced through explicit and implicit channels. The orders of the microprocessor cores are stored in the synchronous dynamic random access memory on the FPGA board, which solves the problem of insufficient storage space for the orders in electromechanical transient simulation. A real-time digital solver for electromechanical transient simulation, whose feasibility is verified by a simulation of part of the power system in East China, is successfully constructed by applying a small number of microprocessor cores and multiple soft function solvers.Keywords: real-time electromechanical transient simulation; field-programmable gate array (FPGA); FPGA-based real-time digital solver (FRTDS); soft function solvers; data cluster transmitter
The Electromechanical Technician Certificate program provides a complete introduction to electronics and electromechanical systems. This program is often of interest to people who want to study electronics with an emphasis on mechanical systems, for example someone coming from a millwright background. The program covers mechanical topics outside of a typical electronics program, like industrial control devices, DC and AC motors and control circuits, transformers, analog and digital transducers, industrial process control and PLCs.
The Electromechanical Technician Certificate, like the Electronics Certificate allows the student to work and complete the computer based program at their own pace, is divided into 24 modules of interactive curriculum each containing text, animations, mini audio lectures, illustrations, review questions, online resources, over 450 pre-built lab projects and practice exams. and integrates the CircuitLogix and 3DLab simulators for laboratory exercises.
One of the main learning features of the Electromechanical Technician program is the complete integration of laboratory experiments and projects within the presentation of the electronics and electromechanical theory. This is accomplished through the introduction of circuit simulation software that simulates the behavior of electronic circuits. Students who enroll in the program receive a licensed copy of CircuitLogix Pro, a leading commercially available simulator that includes both 2D- and 3D-circuit simulation tools.
The 3DLab simulator is introduced early into the content of the program to help students visualize basic electronic circuits and to begin to interact directly with them, just like in a real lab. Animations of the lab simulations supplement the working labs to create a multimedia environment that is very engaging and allows students to virtually step into the laboratory and circuit they are working on.
CircuitLogix is a powerful, yet easy to use schematic capture and circuit simulation tool which includes over 4,000 device models, and eight virtual instruments. The schematic capabilities enable students to draw any electronics circuit and create a netlist for PCB design tools and autorouters. Students can easily build an analog or digital circuit schematic, attach test instruments and run the simulator to see how the circuit functions. It can perform a live, free running simulation of the digital portion of a circuit and also perform analog and mixed analog/digital simulations based on Berkeley SPICE (Simulation Program with Integrated Circuit Emphasis) and XSPICE.
Motion bases for aircraft and other types of simulators demand a combination of rapid acceleration and deceleration, tight positioning control, long life, and, of course high reliability. The larger the mass that needs to be moved, the more likely the motion base will use hydraulics. Manufacturers have been able to increase the capacity of electromechanical actuators, so they present them as preferable to electrohydraulic systems.
However, many of the arguments minimize the advantages of hydraulics over electromechanical systems and exaggerate the disadvantages of hydraulics. Different motion bases have application advantages based on their particular design. Hence, the following analysis is intended for applications where it is necessary to lift and hold payloads for extended periods of time as well as accelerate and decelerate that payload while elevated. Of primary concern are motion bases designed primarily for flight simulation and similar applications.
Assume we need to lift and hold a 20,000 lb payload for extended periods of time. This is a common condition for flight simulators and similar applications where accelerating and decelerating dynamics are small, but large excursions of the platform are required. Such applications typically use six linear actuators arranged in a hexapod configuration.
This point should not be trivialized because users may have to install expensive cooling systems after they discover the higher temperature of the room housing the electric motion base. The bottom line is that electromechanical systems used in typical motion bases consume significantly more energy than electrohydraulic systems do.
Overload capacity
Both electric and hydraulic motion bases are typically designed for a specific application with a clearly defined payload. If the payload should increase, say, by 20%, an electromechanical system probably would become overloaded. Electrical systems depend on precise sizing of their motors. Suppliers rarely oversize these systems because doing so would increase cost, which would jeopardize the supplier winning the contract. If payload increases, the solution is generally to scrap the old system and order a newer, larger, and more expensive motion base.
Performance
Assuming equal design criteria, accelerations and velocities that can be obtained with hydraulic and electric systems are comparable. In theory, electromechanical systems should be capable of higher resolution because most of these systems use an encoder, resolver, or similar feedback transducer. In reality, though, manufacturing tolerances and design and assembly tolerances relegate the true resolution to that comparable to hydraulic systems. Digital accuracy relative to computer programming and theoretical computation can be far different from the actual accuracy once machining and fabrication tolerances are taken into account. Hence, hydraulic and electric systems accuracies are comparable.
Electric motion base systems can be noisy due to the many small, fast-moving parts in the actuators. They generate a loud rushing sound that is distinct and may or may be heard in the enclosure mounted on the motion base. This issue is especially important for flight simulators.
