The Fixed Torque Dynamo and Motor Model solves the coupled differential equations for an electric motor driven by a dynamo (generator).  The model can be used as to illustrate elementary instabilities or bifurcations discussed in courses about nonlinear oscillators and dynamical systems.  When the dynamo is driven at constant torque, chaotic reversals of the generated current and of the angular rotation of the motor are observed.  The main window displays the dynamo angular velocity ?1, motor angular velocity ?2 and current I time series and a second window displays the phase space.  The stator current Is (A), torque T (N•m), and resistance R (ohm) are adjustable.

The Fixed Torque Dynamo and Motor Model was created using the Easy Java Simulations (EJS) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double click the ejs_chaos_FixedTorqueDynamoAndMotor.jar file to run the program if Java is installed.

Please note that this resource requires at least version 1.5 of Java (JRE).
