Shanghai Pinxin Explosion-Proof Electric Motor Co., Ltd. was established on April 12, 2017, with its registered address at No. 83, Lane 1-42, Hongxiang North Road, Wangxiang Town, Pudong New Area, and the legal representative is Sun Hongwen.
Explosion-proof motors are electric motors designed for use in flammable and explosive environments, as they do not produce sparks during operation. They are primarily used in coal mines, oil and gas, petrochemical, and chemical industries. Additionally, they are widely employed in sectors such as textiles, metallurgy, urban gas supply, transportation, grain and oil processing, papermaking, and more. As a key power source, explosion-proof motors are commonly used to drive pumps, fans, compressors, and other conveying machinery.
Key features of explosion-proof motors are as follows:
1. The power ratings, installation dimensions, and speed correspondences are in accordance with DIN42673. Considering the compatibility with the YB series and interchangeability with the Y2 series, necessary adjustments have been made for enhanced effectiveness and applicability.
2. Full series utilizes F-grade insulation, with temperature rise evaluated according to B-grade standards.
3. Noise limits are lower than the YB series, approaching the I-level noise of the YB series; vibration limits are comparable to the YB series.
4. The shell protection rating is upgraded to IP55.
5. The full series is equipped with low-noise deep groove ball bearings, and motors with a base center height of 180mm or above are fitted with oil injection and drainage devices.
6. Motor radiators come in two types: parallel horizontal distribution and radiant distribution, with the former being the primary configuration.
7. Key performance indicators meet international standards from the early 1990s.

Explosion-proof motors employ a flameproof enclosure to separate the electrical components that may generate sparks, arcs, and dangerous temperatures from the surrounding explosive gas mixtures. However, this enclosure is not airtight; explosive gases can enter the motor interior through gaps at the joints of the enclosure. When in contact with ignition sources such as sparks, arcs, or high temperatures inside the enclosure, an explosion may occur. In this case, the motor's flameproof enclosure not only remains undamaged or deformed but also prevents the flame or hot gases from igniting the surrounding explosive gas mixture as they pass through the joint gaps.
The company has obtained certifications including ISO9001 Quality Management System, ISO10012 Measurement and Testing System, RoHS18000, and ISO14001 Environmental Management System. All explosion-proof motors are certified with防爆合格(CQST) by the National Explosion-Proof Electrical Product Quality Supervision and Inspection Center and an Industrial Product License issued by the General Administration of Quality Supervision, Inspection and Quarantine. Additionally, the company holds other certifications such as the Mine Safety Product Mark, China Classification Society Quality Certification, IECEx Certification, CCC Certification, CE Certification, ATEX Certification, and Russia GOST Certification.
