Title:
ELECTRIC CONDUCTION CIRCUIT FOR ELEVATOR
Document Type and Number:
Japanese Patent JPH0597353
Kind Code:
A
Abstract:

PURPOSE: To obtain an electric power economization type elevator having the compact constitution at a low cost by directly utilizing the induced counter electromotive force generated on an armature coil through the descent traveling of a gauge, as the exciting electromagnetic force of an armature coil in the ascent traveling of a gauge, in a multigauge type elevator device driven by a linear motor.

CONSTITUTION: An elevator device carries out the ascent and descent travelings in synchronization at a high speed. When a gauge 9-1 passes through an armature coil 1-1 at a speed V in an ascent system A, a counter electromotive force ER is generated in the direction for suppressing traveling is generated on the armature coil 1-1. When a gauge 9-2 passes through an armature coil 2-1 at a speed V in a descent system B, a counter electromotive force ER generated in the direction for suppressing traveling is generated on the armature coil 2-1. In this case, switches 4-1 and 5-1 are turned ON to connect both the armature coils 1-1 and 2-1, and each counter electromotive force ER is offset. When the gauges 9-1 and 9-2 pass through the armature coils 1-2-1-n and 2-2-2-n, the switches 4-2, 5-2-4-n, and 5-n are turned ON successively.
