The rareearth permanent magnetic auto-synchronous gearless elevator drive control system, suitable for elevator gearless 1:1 drive, is mainly characterized by that it has a four-quadrant operation actuating core formed from rare earth permanent magnetic A.C. synchronous motor, synchronous angular-position pickup, D.C. brushless speed-measuring unit, speed controller and voltage-type SPWM inverter channel with three current control modes, an elevator move ment control core formed from up-computer, I/O locking controller, movement control unit, system state detection unit and display unit, and a heat exchange core formed from brake controller, energy consumption box, cooling controller and fan. Said invention resolves the problem of high energy consumption and low efficiency of traditional elevator with speed-reducing mechanism. |
