OSORIO, John Eduar; PEREZ RAMIREZ, Juan Daniel  e  RODRIGUEZ BARRERA, Mario Alberto. Data acquisition system implementation to monitor a direct current machine. Tecnura [online]. 2010, vol.14, n.27, pp.60-68. ISSN 0123-921X.

On this paper, we present a Data Acquisition System Implemented to monitor the mechanic and electric variables in a direct current machine. Tension, current, torque, and speed signals are captured by means of suitable transducers to be sent to a personal computer (PC) to observe their behavior and the relation between them, on different working states in the machine. A laboratory tool is given to offer the view and analysis of the behavior in rotative electric machines, promoting alternative ways in teaching processes, in this area as well as in subjects such as graphical programming and instrumentation.
