TUGGING DEVICE FOR TESTING MODEL SHIP

摘要

PURPOSE: A tugging device is provided to tug a model ship to be fixed in a trailer by traveling the trailer through a linear induction motor. CONSTITUTION: An inverter unit(50) converts three-phase power of a power supplying unit(40) to three-phase power of variable frequency and variable current. A linear induction motor unit(60) drives a trailer(20) through an induction field on a rail by receiving the three-phase power of variable frequency and variable current. Thereby, a tugging device is compacted and noise is reduced.
