Explosion-proof motor for safety enhancement ≪Certified by an explosion-proof type testing agency≫
The totally enclosed external fan factory safety increased explosion-proof electric motor is designed to enhance safety by considering its structure and temperature rise to prevent the occurrence of sparks, arcs, or overheating during operation.
● Products certified by an explosion-proof type testing agency Products certified by the Ministry of Health, Labour and Welfare designated explosion-proof type testing agency ● Usable in Zone 2 hazardous locations Can be used in areas where the likelihood of generating an explosive atmosphere is low under normal conditions, and if generated, it lasts only for a short time ● Ignition degree G3, explosion grade d3 Acetone, ammonia, acetic acid, carbon monoxide, ethane, toluene, ethyl acetate, methanol, propane, benzene, methane, carbon dioxide, water gas, hydrogen (G1) Ethanol, isopentyl acetate, butane, 1-butanol, acetic anhydride, ethylene, ethylene oxide, acetylene (G2) Gasoline, hexane (G3) The structure of the safety-increased explosion-proof motor considers the following: - The temperature rise limit of the windings is kept lower than usual according to the temperature class - Surface distance, insulation space distance, etc., are larger than general values - Terminal box cover bolts are designed to be lockable to prevent disassembly by non-experts - The temperature rise in parts that may come into contact with explosive gases is kept below the temperature determined according to their ignition degree - Allowable confinement time is 7 to 10 seconds Sangmei Co., Ltd. is an authorized distributor (trading company) of Nidec Techno Motor Corporation.

Company information
Until now, we have continuously faced challenges with the desire to propose optimal system integration to our customers while sensitively responding to the trends of the times in industries such as paper, pulp, automotive, automotive parts, semiconductors, LCDs, and smartphones. Moving forward, we will actively enter the "three industries" of "food, pharmaceuticals, and cosmetics," which are essential for people's lives, while inheriting this way of thinking. Additionally, in fields expected to grow, such as semiconductors and high-performance LCDs, we will actively engage in the development and manufacturing of precision alignment exposure equipment, inspection equipment, and process manufacturing equipment as a device manufacturer.
