Product Introduction

YBF3 series explosion-proof motor is specially designed and manufactured by our company for supporting explosion-proof axial fans, and is suitable for underground coal mines and factories. Its power grade, installation size in line with the International Electrotechnical Commission (IEC) standards, explosion-proof. The classification and temperature grouping of common explosive gas mixtures are the same as YB3 series flameproof three-phase asynchronous motor.

The motor with center height of 160 and above for local fan and the center height of 250 and above for main fan is equipped with oil injection and drainage devices. The position of the bearing temperature measuring element is reserved for the center height of the motor for the main fan of 250 and above. The length of the lead pipe of the cable connection device for the fan use can be customized according to the user's requirements.
