Marchant XLA calculator, based on Friden's design. The Marchant Calculating Machine Company was founded in 1911 by Rodney and Alfred Marchant in Oakland, California.. The company built mechanical, and then electromechanical calculators which had a reputation for reliability.
In electrical engineering, electric machine is a general term for machines using electromagnetic forces, such as electric motors, electric generators, and others. They are electromechanical energy converters: an electric motor converts electricity to mechanical power while an electric generator converts mechanical power to electricity.

[1] [2] [3] This machine had a 13-digit capacity and a 5-inch CRT display. It used a magnetostrictive delay-line memory, to save money on expensive transistors. The EC-130 sold for $2,200 (equivalent to $21,900 in 2023), or about three times the price of comparable electromechanical calculators of the time.

Archimedes LK 14, an electro-mechanical calculator exposed at the Specola Museum in Bologna, Italy Full-keyboard machines, including motor-driven ones, were also built until the 1960s. Among the major manufacturers were Mercedes-Euklid, Archimedes, and MADAS in Europe; in the USA, Friden, Marchant, and Monroe were the principal makers of rotary ...
Electromechanical engineering (alternatively written as electromechanical eng., or electro-mechanical eng.) refers to the analysis, design, manufacture and maintenance of equipment and products based on the combination of electrical/electronic circuits and mechanical systems.
