YBX3 Series Explosion Proof Three Phase Asynchronous Motor

YBX3 series premium efficiency flameproof three phase asynchronous motor is totally enclosed, self fan cooling, squirrel cage type. The efficiency class is in accordance with Chinese national standard GB18613一2012 class II, as well as IEC60034一30 high efficiency standard(IE3). It has high operational safety, excellent performance, low noise and vibration and meets the need of environment protection.

YBX3 Series Flameproof Three Phase Asynchronous Motor Application and Adanvatage：

YBX3 series motor is suitable for equipment in places where flammable gas containing certain components or explosive mixtures of steam and air exist. It’s mainly used in petroleum and chemical industry, also widely applied in textile, metallurgy, city gas, transportation, grain and oil processing, paper, medicine and other industries. The efficiency index conforms to the value of grade 2 specified in GB18613-2012 Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Small and Medium Three-phase Asynchronous Motors.

The remarkable characteristics of this series motor are high efficiency and energy conservation, as well as large temperature rise margin, long lifetime, small vibration, low noise and high reliability. And auxiliary equipment such as winding temperature sensor, bearing temperature sensor, temperature transmitter and heater can be installed according to user needs.
