New Type of C & C Motor (110V)

DCS 1889 motor 400

July 16, 2019

The other day I came across an interesting article that takes us back to some early innovations regarding the use of electric motors in manufacturing facilities. The article titled “The Electric Motor in Factories”, and was published in Science by the American Association for the Advancement of Science in 1889. [1]

The article follows a group of individuals from the New York Electric Society and the American Institute of Electrical Engineers as they tour the factory of the C. & C. Electric Motor Company. The focus of the tour was on the engine room and the manner in which the entire factory was driven from the engine room not by massive belts passed through the floor to power equipment motors, as was the standard at the time, but with shafting. Shafting in 1889 was somewhat revolutionary and allowed for less power to operate the factory and allowed for easier maintenance and shut down of particular manufacturing lines or divisions.

The engine itself was belt driven direct to a 50,000W Edison wound dynamo that furnished the power to light the building and power the motors that drove heavy machine such as lathes, planers, drill-presses and milling machines. In total there were around 30 such heavy machines throughout the factory. The touring group was quite impressed that to run all of these machines only four motors were being used, two 3.5 hp and two 1 hp. However, the group did note that many of the machines were only in operation for short periods and the machines would not be used simultaneously.

It was also noted the current for the incandescent light bulbs required a heavy draw, although it never exceeded 18 hp, and during peak daytime hours that could drop to 12 hp. “The average load on the dynamo is about 40 amperes, or about 12 electrical horse-power, which covers both light and power. The friction load on the engine is 6.4 hp, giving us a total of about 20-22 hp on the engine. The power which would be required to operate the factory in the usual way, by belting through the floors, was estimated to be between 30 and 50 hp, without considering the power required for the lights, amounting to an additional 15 hp.” [2]

It is always interesting to look back and see how some minor changes to the way we operate can have substantial benefits, a point we are still refining today. Motors and operations have come a long way, but at times we benefit from simply looking at the minor differences in how another operates or makes use of the same products you do, it might just benefit how you operate as well.

BrakingResistor1When designing a motor control system, it is not always clear if a braking resistor is required and, if it is, how to proceed in selecting a braking resistor. This post is intended to simplify that process so it is clear when and how to select a braking resistor for your application. 

Why are braking resistors necessary?

Braking resistors are introduced into a motor control system in order to prevent hardware damage and/or nuisance faults in a VFD. They are required because in certain operations, the motor controlled by the VFD is acting as a generator and power is flowing back towards the VFD, rather than towards the motor.

Maplesoft™ announced the release of MapleSim™ Insight, a new software product from Maplesoft that gives machine builders powerful, simulation-based debugging and 3-D visualization capabilities that directly connect to their automation tools. As a result, engineers can perform simulation-based testing of their controller easily and efficiently.

Simulation-based testing of machine control strategies is a key element of virtual prototyping and using digital twins for virtual commissioning. However, this step can be cumbersome, as many automation tools provide limited options for machine-level, simulation-based controller testing, and these options often require moving development to an entirely new platform.
