YB3 series flameproof three-phase asynchronous motor is an updated product of YB2 series. This series of motors is characterzied with high efficiency and energy saving, large temperature increase margin, small size, light weight, beautiful appearance, reliable operation, good performance, low noise, low vibration, and convenient use and maintenance. The efficiency index of this series of motors conforms to the motor energy efficiency level 3 described in GB18613-2012 Minimum allowable values of energy efficiency and energy efficiency grades for small and medium three-phase asynchronous motors. Its power grade and installation size conform to IEC standards and are the same as YB2 series motors. The explosion-proof performance of this series of motors meets the requirements of the GB3836.1-2010's Explosive Environment Part 1: General Requirements and the GB3836.2-2010's Explosive Environment Part 2: Equipment Protected by Explosion-proof Enclosure D. The explosion-proof Exd Ⅰ Mb, Exd Ⅱ AT4 Gb, Exd Ⅱ BT4 Gb, Exd Ⅱ CT4 Gb products are suitable for dangerous places in explosive gas environment with ⅡA, ⅡB, ⅡC and temperature groups of T1 ~ T4 respectively in underground coal mines (non-mining faces) and factories. On the basis of YB3 motor, it can also be made into YB3-W outdoor model, YB3-TH indoor humid model, YB3-WTH outdoor humid model, YB3-WT outdoor tropical model and YB3-WF1 outdoor model, which are suitable for using in the medium anti-corrosion climate environment.

Oil pump motor (frame No. (80-355)) is an improved specific motor for driving the oil pump. The oil pump motor includes a motor body, a front end cover and an output transmission shaft. A stepped hole is opened on the front end cover. The output transmission shaft is retracted into the front end cover. It is a hollow shaft with internal spline teeth. The input drive shaft between the shaft and oil pump is matched in the form of splines. The connection between the pump and the motor does not use the traditional coupling and bracket method, but directly inserts the pump shaft into the motor shaft hole, thus having the following advantages: 1. Because the shaft hole and flange stop of the motor are processed with high precision, the concentricity of the two can be ensured after assembly, which better solves the noise and vibration caused by the disconcentricity of the pump and the motor. 2. Simple installation, compact structure and small space occupation. 3. The rotating part is not exposed, thus it is safe and reliable. The explosion-proof performance of this series of motors meets the requirements of the GB3836.1-2010's Explosive Environment Part 1: General Requirements and the GB3836.2-2010's Explosive Environment Part 2: Equipment Protected by Flameproof Enclosure D. These motors are made intoⅠ Mb,Exd Ⅱ BT4 Gb ,Exd Ⅱ CT4 Gb, and meet the national standard GB12476.1 Electrical Equipment for Combustible Dust Environment Part 1: General Requirements and GB12476.5-2013 Electrical Equipment for Combustible Dust Environment Part 5: Enclosure Protection tD , explosion-proof marks are Ex tD A21 IP65 T130℃ and Ex tD A22 IP55 T130℃。

YBK3 series flameproof three-phase asynchronous motor is a special motor designed for coal mine mining machinery. The base is welded and formed by steel plate. The air hood, junction box and insulation structure are strengthened. The electrical performance, installation size and rated power are the same as those of YB2 motor. The explosion-proof performance of this series of motors meets the requirements of the GB3836.1-2010 Explosive Environment Part 1: General Requirements and the GB3836.2-2010 Explosive Environment Part 2: Equipment Protected by Flameproof Enclosure D standards, and is made into a flameproof Exd Ⅰ Mb, which is suitable for underground mining faces in coal mines.

YBEJ series flameproof electromagnetic brake three-phase asynchronous motors are suitable for electric driving in underground coal mines (non-mining working faces) and factories containing explosive gas mixtures. This series of flameproof electromagnetic brake three-phase asynchronous motors is a three-phase asynchronous motor that is fully enclosed, self-fan-cooled, squirrel-cage, and attached to a disc friction dry-type loss DC electromagnetic brake. This series of motors are characterized with rapid braking, accurate positioning, simple structure, easy to use and easy to maintain, and are widely used in various machines that require rapid stop, accurate positioning and reciprocating motion to prevent sliding. YBEJ series electromagnetic brake three-phase asynchronous motors are used in places without explosive gas mixture in factories. The electrical performance and braking functions of the two series motors are the same. The installation dimensions of YBEJ series flameproof electromagnetic brake three-phase asynchronous motors are the same as those of YB3 series motors. This series of motors have the advantages of high efficiency and energy saving, large temperature increase margin, small size, light weight, beautiful appearance, reliable operation, good performance, low noise, low vibration, and convenient use and maintenance. The explosion-proof performance of the motor meets the GB3836.1-2010 Explosive Environment Part 1: General Requirements for Equipment and GB3836.2-2010 Explosive Environment Part 2: Equipment Protected by Flameproof Enclosure D, explosion-proof marks are Exd Ⅱ BT4 Gb, Exd Ⅱ
