A4300 – MULTIFUNCTION MULTIFUNCTION ELECTRICAL MACHINE SYSTEM This Trainer consists of a set of modular components that can be assembled in different configurations to construct most rotating machines such as: 2 and 4 poles AC squirrel cage motor 2 poles AC slip ring motor Single phase AC capacitor motor Single phase AC repulsion motor AC synchronous motor AC synchronous generator AC/DC universal motor DC series excitation machine DC shunt excitation machine DC compound excitation machine DC independent excitation machine The components are: One AC stator One DC stator One squirrel cage rotor One slip ring rotor and brush set One collector rotor and brush set One starting capacitor Coupling base Safety guard The stators are permanently mounted on a coupling base on which four supports hold the rotors and brush sets.
The supports are fastened by means of knobs that can be easily removed without the need of any tool, to exchange the rotors and brushes and implement the desired configuration. A compact and integrated laboratory is made available to perform most experiments and tests on standard electrical machines. The advantages are obviously its lower cost compared to that of a set of discrete machines, their modularity and, owing to the complete visibility of the components, the possibility for the student to learn the electrical and mechanical details. The windings are connected to terminal boards on top of which they are clearly identified by drawings that show the internal logic and make their understanding and connections easy in the different possible combinations. The synchronous machine is in all respect a real implementation and not a simulated function of the asynchronous unit. A brake generator can be easily connected coaxial to the trainer for performing load tests. A manual supplied with the unit describes in detail the electrical connections and the mechanical assembling procedure
