Overview:

DC Compound Motors have been a cornerstone of industrial applications for over a century. This educational model is ideal for both academic and industrial training purposes, allowing hands-on exploration of the structure, functionality, starting techniques, maintenance, and behavior of compound DC machines.

This system is engineered to offer students and trainees the ability to connect and analyze various characteristics of DC compound motors and generators. Through the provided terminals, users can study multiple parameters including speed control, torque behavior, excitation effects, and machine performance in motor and generator modes.
