The EMC E4 was a 2,000 horsepower (1,500 kW), A1A-A1A passenger train-hauling diesel locomotive built by the Electro-Motive Corporation of La Grange, Illinois. All were built for the Seaboard Air Line Railway. The E4 was the fifth model in a long line of passenger diesels of similar design known as EMD E-units.

EMD E-units were a line of passenger train streamliner diesel locomotives built by the General Motors Electro-Motive Division (EMD) and its predecessor the Electro-Motive Corporation (EMC). Final assembly for all E-units was in La Grange, Illinois. Production ran from May 1937, to December, 1963.

2024年8月27日 · The E4 was built in 1938-1939, and along with the E3 was the first such model to feature a GM prime mover (the model 567) and not a Winton engine. The E4 featured two 12-cylinder 567s enabling it to produce 2,000 horsepower. As with all other models up to that time the model was equipped with A1A-A1A trucks and GM-built, model D7 traction motors.

2023年6月23日 · EMC 分为：EMS和EMI,总的来说就是待测设备干扰别人的程度，待测对别人干扰忍受的程度。 具体分为如下几个点： 其中IEC为国际建议标准，EN为欧盟标准，出货欧盟需要法律强制性认证，这也是为什么我们测试一般都是EN标准。 EMC问题越早考虑、越早解决，费用越小、效果越好。 传导测试：一般也被叫做骚扰电压测试，被测产品对公共网络的干扰，测试L和N 这两根线。 有电源线的电子电气产品都需要做传导测试，当然很多需要直流供电的产品也涉 …

2019年11月4日 · 电磁兼容EMC（Electro Magnetic Compatibility)：是一门新兴的综合性学科，是电子、电气设备或系统的重要技术 性能。 国家标准GB/T 4365-2003《电磁兼容术语》对电磁兼容所下的定义为“设备或系统在其电磁环境中能正常工作且不对该环境中任何事物构成不能承受的电磁骚扰的能力”，即电子、电气设备或系统在同一电磁环境中能良好执行各自功能的这样一个共存状态，简单点说， 就是各种设备都能正常工作又互不干扰，达到“兼容”状态。 要注意电磁兼容所 …

2019年6月17日 · emc（电磁兼容）包括ems（电磁敏感度）和emi（电磁干扰）两部分，通常我们所说的解决emc问题，其实就是解决电子设备对外辐射干扰，或者如何防止设备、电子元件被外界电磁波干扰的问题。

处理 电磁兼容性 （EMC）问题是确保电子设备在电磁环境中能够正常运行且不会对周围的其他设备造成干扰的重要任务，是硬件工程师的重要工作。在处理EMC问题时，常用的方法包括使用 磁珠 、电感和 电容 这三种组件。 1-磁珠（Ferrite Beads）抑制的原理和应用范围

2025年2月13日 · 要理解 EMC，首先得清楚它包含两个关键方面：电磁干扰（EMI）和电磁敏感性（EMS）。 EMI 指的是设备在运行过程中向外界辐射电磁波，从而干扰其他设备的正常工作；而 EMS 则体现了设备对外部电磁干扰的抵抗能力。 这两者相互关联，共同决定了设备在复杂电磁环境中的兼容性。 就好比一个和谐的社区，每个 “居民”（设备）既要做到不打扰他人（低 EMI），又要具备不受外界干扰的 “定力”（高 EMS）。 频谱在 EMC 中扮演着重要角色。 频率的变化会 …

2024年10月11日 · EMC全称Electromagnetic Compatibility，即电磁兼容，要求电源模块等电子设备内部没有严重的干扰源及设备，或电源系统有较好的抗干扰能力。 它们的关系是：有了EMI也就有了EMC，满足EMS要求才能实现EMC，EMC测试是包含EMI和EMS的。 EMI电磁干扰是合成词，应分别考虑电磁和干扰，干扰是指设备受到干扰后性能降低以及对设备产生干扰的干扰源这俩层意思。 第一层意思如雷电使收音机产生杂音、拿起电话后听到无线电声音等。 第二层含义就 …
