A novel speed control approach in parallel-connected induction motor by using a single inverter and electronic virtual line-shafting Conference Paper uri icon


  • The main purpose of this paper is to present a simple strategy to control speed of parallel connected multi-induction motor fed by a single inverter. In this paper, it is proposed a novel smart switching strategy to control the voltages necessities of each motor and it is applied the Electronic Virtual Line Shafting (EVLS) for speed synchronization. Simulation and experimental constrains in a two 1.1 kW induction machines test ring both running single V/Hz scheme and fed by a single inverter are presented showing the advantages and limitations of this technique during different load conditions. © 2005 IEEE.
