Troubleshooting Servo Motor Systems

The History of Servo Motors

Electric motors came to fruition due to the invention of the battery (A. Volta, 1800), the electro magnet (W. Sturgeon, 1825) and the discovery of a magnetic field from electric current (H. C. Oersted, 1820). The first working rotating electric motor was introduced in May 1834 by Moritz Jacobi. In 1838, Jacobi reintroduced an improved and more powerful motor. However, these electric motors were large and weak compared those we use today. The early motors were single-phase, one-directional, and more expensive to operate than steam engines so the research continued. Over more than a century, motors have become more powerful due to inventors and developers throughout Europe and America, such as Volta, Joule, Siemens, Ampere, and Tesla.

The 1880s realized the three-phase electric power system that cannot be attributed to any single inventor. However, it was Nikola Tesla and his employer, George Westinghouse, who are responsible for the first U. S.
power line that crossed the Niagara Falls at Buffalo, NY in 1896. This delivered an output of 750 kilowatts at 11 volts or less.

Today we have the three-phase synchronous motors that are used in highly dynamic applications, the DC motor which is still used in devices that require less power, the AC motor, and specifically, the servo motor. Advances in inverters (electrical conversion systems) and drive control systems that combine inverters and motors have brought about technological advances that we now take for granted. Electric motors power nearly everything in our lives today. From automobiles to home appliances to industrial devices and tools such as locomotives and table saws.

Servo motors were designed to work within a closed-loop control system. Servo motors provide precise control of position (angular or linear), velocity, and acceleration. These devices are seldom seen but are used by an average person daily: The sliding doors at the supermarket; the power windows in a car; the elevator at the office, and the ice delivery system on a refrigerator. Servo motors are so sophisticated that they are used in robotic manufacturing, such as those used to assemble automobiles, and CNC machines such as variable speed routers that carve intricate designs into wood furniture.

While the invention of electrical motors is in the past, the research and development into new technology continues.
