Control and Adjustment of Linear Induction Motor Starting Force

摘要

Although application areas of linear induction motors (LIM) and on it base designed linear electric drives expand [1-6], LIM and linear electric drives are not mass-produced, because every time LIM and linear electric drives need to be adjusted to specific control equipment to make linear electric drives more advanced then movement produced by rotary asynchronous motor and connecting links used to change rotary to linear motion. Therefore it is necessary to design new LIM and produce new linear electric drives for each application. The force-speed characteristics of designed and produced new LIM and linear electric drives frequently do not fit the specification and they require some adjustment. The industry automatics uses small power LIM widely with linear force-speed characteristics.
