Embodiment Construction

[0024] figure 1 An elevator system 10 is depicted in accordance with an embodiment of the present disclosure. figure 2 is a block diagram of components of elevator system 10 in an exemplary embodiment. Elevator system 10 includes elevator car 23 configured to move vertically up and down within hoistway 51 along a plurality of car guide rails 61 . Elevator system 10 also includes a counterweight 28 operatively connected to elevator car 23 via pulley system 26 . The counterweight 28 is configured to move vertically up and down within the hoistway 51 . The counterweight 28 moves in a generally opposite direction to the movement of the elevator car 23, as is known in conventional elevator systems. The movement of the counterweight 28 is guided by a counterweight rail 63 installed in the hoistway 51 .

[0025] The elevator system 10 also includes an alternating current (AC) power source 12 , such as an electrical backbone (eg, 230 volts, single phase). AC power is provided fr...

Abstract

An elevator system includes an elevator car; a machine to impart motion to the elevator car; a brake to stop rotation of the machine, the brake comprising a first coil and a second coil, wherein removing power from the first coil and the second coil applies the brake to the machine; and a controller in communication with the brake, the controller configured to connect the first coil and the secondcoil in one of a first electrical configuration and a second electrical configuration.

Description

Background technique [0001] The subject matter disclosed herein relates generally to the field of elevator systems, and more particularly to controlling the electrical configuration of coils in elevator brakes to control braking time. [0002] In existing elevator systems, a machine drives the traction sheave to impart motion to the elevator car. The brake is used to stop the rotation of the traction sheave and to stop the movement of the elevator car. Typically, the brakes consist of a single electric coil that falls down immediately upon an emergency stop. Due to the high instantaneous braking torque, the car can stop quickly, causing discomfort to the passengers. Contents of the invention [0003] According to one embodiment, an elevator system includes an elevator car; a machine that imparts motion to the elevator car; a brake for stopping rotation of the machine, the brake including a first coil and a second coil. two coils, wherein removing power from the first coil...
