Computer Simulation of Electric Drive with Induction Motor and Fluid Coupling

A new approach to the shaft load simulation with the different types of fluid coupling is introduced herein. The presented simulation results are obtained for an electrohydrodynamic drive at different load modes and types of fluid coupling such as: with constant filling; static self-emptying (traction fluid coupling) and dynamic self-emptying (limiting fluid coupling). The chapter also provides an example of fluid coupling parameters and characteristics as well as depicts the following operation modes of the system: acceleration; no-load; load and overload on the turbine shaft.
