Abstract

Purpose The purpose of this study is to propose an extended reliability method for an industrial motor drive by integrating the physics of failure (PoF). Design/methodology/approach Industrial motor drive systems (IMDS) are currently expected to perform beyond the desired operating conditions to meet the demand. The PoF of the subsystem affects its reliability under such harsh operating circumstances. It is crucial to estimate reliability by integrating PoF, which helps in understanding its impact and to develop a fault-tolerant design, particularly in such an integrated drive system. An integrated PoF extended reliability method for industrial drive system is proposed to address this issue. In research, the numerical failure rate of each component of industrial drive is obtained first with the help of the MIL-HDBK-217 military handbook. Furthermore, the mathematically deduced proposed approach is modeled in the GoldSim Monte Carlo reliability workbench. Findings From the results, for a 15% rise in integrated PoF, the reliability and availability of the entire IMDS dropped by 23%, resulting in an impact on mean time to failure (MTTF). Originality/value The integrated PoF of the motor and motor controller affects industrial drive reliability, which falls to 0.18 with the least MTTF (2.27 years); whose overall reliability of industrial drive drops to 0.06 if it is additionally integrated with communication protocol.

基于GoldSim蒙特卡罗可靠性工作台的经典工业电机驱动可靠性研究

本研究的目的是整合故障物理(PoF)，提出一种扩展的工业电机驱动可靠性方法。设计/方法/方法工业电机驱动系统(IMDS)目前有望超出预期的运行条件，以满足需求。在如此恶劣的运行环境下，子系统的PoF影响着子系统的可靠性。通过集成PoF来评估可靠性至关重要，这有助于理解其影响并开发容错设计，特别是在这样的集成驱动系统中。针对这一问题，提出了工业驱动系统集成PoF扩展可靠性方法。在研究中，首先借助MIL-HDBK-217军用手册获得了工业传动各部件的数值故障率。此外，在GoldSim蒙特卡罗可靠性工作台中对数学推导出的方法进行了建模。从结果来看，集成PoF每增加15%，整个IMDS的可靠性和可用性就会下降23%，导致平均无故障时间(MTTF)受到影响。原创性/价值电机和电机控制器的集成PoF影响工业驱动可靠性，其降至0.18,MTTF最小(2.27年);若再集成通信协议，其工业驱动器的整体可靠性降至0.06。
