COM3LAB Course: Electrical Machines I

Comprises an experiment board, housed within a board carrier, for use in conjunction with, and powered by the Master Unit (700020, supplied separately) teaching a course concerning the connection methods and the recording of characteristics of electric motors and generators, experiments being wired by using 2 mm safety cables (700022, supplied separately). With the integrated machine test system, a multitude of experiments can be carried out, for example the recording of torque, power and current-locus curves. Course content, experiment instructions and tasks are taught via course-specific software.
