Mathematical Model of Inductive Effect on the Multi-motors Synchronization Systems

Systems of synchronous rotation with AC machines depend on the equality of speed of two or more induction motors (mechanical or non mechanical-shaft connected) with the existence of load differences allocated on these shafts. The most popular ones among non-mechanical-shaft synchronization systems are the synchronization systems with auxiliary machines, electrical shaft systems, and the electromagnetic working shaft systems. In this work, using MATLAB – SIMULINK program, we suggest a mathematical model which represents a synchronous drive with electromagnetic working shaft system. The model will be tested with two similar induction motors 5hp, 50 Hz, 380 line voltage. Principle of operation and advantages related to the synchronous capability and recovery time for the electromagnetic working shaft system in deferent operational stats were also studied.
