摘要： An apparatus and method for adding a velocity transducer to an electric motor, such as an elevator drive motor, includes mounting a shaft extension on an end surface of a motor shaft by drilling and tapping a bore at the shaft center as parallel as possible. A fastener with a bevel washer between a pair of flat washers attaches the extension to the motor shaft. With the fastener assembly snug, the extension is trued radially with a dial indicator. The bevel washer functions as a spring lock and distributes any off center clamping force produced from non-concentric hole drilling. A shoulder on the extension abuts the motor shaft end surface to maintain parallelism of the longitudinal axes of the shaft extension and the motor shaft. The shaft extension can be formed of an electrically nonconductive material to isolate the transducer from the drive equipment.

摘要： An apparatus for use during modernization of a group of elevators to maintain optimum service to a building includes an Interim Traffic Manager (ITM) system which evenly distributes hall call routing between old and new elevator controls. During the time that an elevator to be re-equipped is out of service, the original not yet re-equipped elevators, as well as the already re-equipped elevators, respond as a single bank, one elevator car per call. The ITM system is connected between the hall call registering devices and each of old and new elevator controls. When a floor push button is pressed, the ITM system uses a routing algorithm to decide whether to send the call to the old or to the new elevator control based upon traffic loading. The ITM system is an inexpensive, reusable unit which resides on the job site temporarily and, therefore, adds no additional costs to the modernization of an elevator group. Technical knowledge required for the installation of the ITM system is restricted to connecting wiring to the elevator controls and the hall call registering devices.
摘要翻译： 在一组电梯的现代化期间使用以维持对建筑物的最佳服务的装置包括临时交通管理器（ITM）系统，其在旧电梯和新电梯控制之间均匀地分配门厅呼叫路由。 在重新装备的电梯不能使用的时间内，原来尚未重新装备的电梯以及已经重新装备的电梯作为单个银行响应，每次呼叫一个电梯轿厢。 ITM系统连接在门厅呼叫注册设备和每个旧电梯和新电梯控制器之间。 当按下地板按钮时，ITM系统使用路由算法来决定是否根据流量加载将呼叫发送到旧的或新的电梯控制。 ITM系统是一个廉价的可重复使用的单元，临时驻留在作业现场，因此不会增加电梯组现代化的额外成本。 安装ITM系统所需的技术知识仅限于将接线连接到电梯控制装置和门厅呼叫登记装置。
