Remote control transport system - has multi- winding three=phase motors in pairs coupled to control circuits which regulate drag

摘要

The remote control transport system uses three phase motors with multi windings. The motors are grouped in pairs with each pair having three windings between them and coupled into control circuits so that one motor provides a set drag. The system allows smooth acceleration and retarding control so that the transport units can be started and stopped at preset points for load transfer. The system can move liquid containers without spillage and can be controlled by simple circuits.
