电梯制动器的可调制动控制器、电梯制动器和电梯
摘要：
一种电梯制动器的可调制动控制器包括：DC总线；用于将制动控制器连接到第一励磁线圈的第一端子；用于将制动控制器连接到第二励磁线圈的第二端子；耦合在第一端子与DC总线之间的第一可控功率开关，该第一可控功率开关被配置为响应于第一控制信号而从DC总线向第一励磁线圈供应电力；耦合在第二端子与DC总线之间的第二可控功率开关，该第二可控功率开关被配置为响应于第二控制信号的第二励磁线圈而从DC总线向第二励磁线圈供应电力；以及控制器，被配置为生成分别用于控制第一和第二功率开关的第一和第二控制信号。该控制器具有：制动断开模式，其中第一和第二控制信号具有相同的指定模式；制动保持模式，其中第一和第二控制信号具有不同的指定模式。
摘要（英）：

An adjustable brake controller of an elevator brake comprises - a DC bus; - first terminals for connecting the brake controller to a first magnetizing coil; - second terminals for connecting the brake controller to a second magnetizing coil; - a first controllable power switch coupled between the first terminals and the DC bus, the first controllable power switch being configured to supply electric power from the DC bus to the first magnetic coil responsive to a first control signal; - a second controllable power switch coupled between the second terminals and the DC bus, the second controllable power switch being configured to supply electric power from the DC bus to the second magnetizing coil responsive to a second control signal; and - a controller configured to generate the first and the second control signals for controlling the first and second power switches, respectively. The controller has: a brake open mode, wherein the first and second control signals have a same specified pattern, and o a brake holding mode wherein the first and second control signals have different specified patterns.
