Explosion-proof motors available in stock We will deliver within 7 days to meet your delivery schedule. 【What is an explosion-proof motor?】 In factories and plants, flammable gases and vapors are present. When these mix with air and come into contact with an ignition source, an explosion or fire can occur. This motor is designed with measures to eliminate such ignition sources. 【Available stock models】 ■ Pressure-resistant explosion-proof motors, explosion-proof grade d2G4 - Foot-mounted type, output 0.4 to 3.7 kW, 4 poles - Flange type, output 0.4 to 0.75 kW, 4 poles ■ Increased safety explosion-proof motors, explosion-proof grade eG3 - Foot-mounted type, output 0.2 to 0.75 kW, 2 and 4 poles - Flange type, output 0.2 to 0.75 kW, 2 and 4 poles

As part of the "Hometown Ibara Future Creation Human Resource Development Project," we welcomed local elementary and middle school students to the special summer program "Ibara Job Exploration Tour 2025," a collaboration between the Ibara City Chamber of Commerce and the Corporate Branding Committee. We conducted a presentation that clearly and enjoyably introduced how our technology supports society, allowing the children to learn about the appeal of manufacturing and the significance of working while interacting with actual devices and products. Through this initiative, we hope to deepen our connection with the community and nurture the curiosity of the children who will carry the future. We sincerely thank everyone who participated, as well as all those involved in planning and organizing the event.
