The Yinmengda series high-efficiency dust explosion-proof three-phase asynchronous motor is a fully enclosed, self fan cooled high-efficiency motor. The efficiency of this series of products meets the requirements of GB18613-2020 energy efficiency level 3 standard.

Dust explosion-proof motors can be used in food or feed processing, wood processing, flour processing or storage, as well as in places with combustible dust such as metals, chemicals, synthetic resins, agricultural products, various fibers, fuels, etc. The specific types of dust can be found in the "Examples of Dust Characteristics", but this motor is not suitable for electrical equipment used in coal mines and ground installations where gas and/or combustible dust pose a danger. It is also not suitable for explosive dust or self igniting substances (such as phosphorus powder) that can burn without the need for oxygen in the atmosphere.

The explosion-proof performance of the Yinmengda dust explosion-proof motor complies with the provisions of GB/T 3836.1-2021 "Explosive Atmosphere Part 1: General Requirements for Equipment" and GB/T 3836.31-2021 "Explosive Atmosphere Part 31: Equipment Protected by Dust Ignited Enclosures", and is applicable to Zone 21 and Zone 22 of explosive dust environments.

To better respond to climate change, quickly respond to market demand, focus on innovation that improves energy efficiency and reliability, and promote industrial green and low-carbon transformation and sustainable development. On July 1, 2023, Siemens integrated its related businesses in the fields of low to high voltage motors, gear motors, medium voltage inverters, and electric spindles to establish Innometrics GmbH. Yinmengda is headquartered in Nuremberg, Germany, with operations in 49 countries worldwide, 16 factories, and approximately 15000 employees worldwide.

With over a hundred years of technological accumulation and innovation, Yinmengda will focus on the professional fields of motors and large-scale transmissions. As a leading enterprise in the industry, Yinmengda will continue to promote industrialization and sustainable development.

Yinmengda has 5 operating companies (including 1 regional headquarters and 4 factories), 13 branch offices, and 6 R&D centers in China. Among them, the "Yinmengda Low Voltage Motor Division Global R&D Center" has been established in Nanjing, with a total of about 3500 employees. It is Yinmengda's main R&D and manufacturing base worldwide.

Yinmengda Electric (China) Co., Ltd., formerly known as Siemens Electric (China) Co., Ltd., officially began operations on March 1, 2006 and was renamed in May 2024. From being awarded the National Green Factory award in 2018, to being recognized as a National High tech Enterprise in 2019, and to having won the Siemens China Best Operating Factory award five times in total, Innovent Electric (China) Co., Ltd. has been committed to providing customers with innovative, efficient, and sustainable electrical solutions.

The company has more than 2000 employees, covers an area of 182000 square meters, and produces approximately 1 million motors annually. It is the largest research and production base for low-voltage and high-efficiency motors in China for Yinmengda.
