Coal Mine

There are many mining production in China that need motors. For example, coal mine and metal mines. The coal mine in Datong, Shanxi Province in September 2019 Ordered 30 sets of YB3 series motors produced by Milestone Motor . In the same year, the coal mine in Liupanshui ordered 30 sets of YBX3 series motors.

YBX3 series flame-proof (ExdIIBT4) three-phase asynchronous motor (frame size 80~355) is characterized by high efficiency, low noise, small vibration, high locked rotor torque, reliable operation, beautiful appearance, etc. It is one of the important electrical products used in the petroleum, chemical and coal industries.

The flameproof performance of this series of motors complies with GB3836.1-2010 Explosive Atmospheres - Part 1: General Requirements for Equipment and GB3836.2-2010 Explosive Atmospheres - Part 2: Equipment Protected by Flameproof Enclosures "d". The mechanical and electrical performance of the product complies with JB/T 12628-2016 Technical Conditions for YBX3 Series High Efficiency Explosion proof Three phase Asynchronous Motor (base No. 63~355).

YBX3 series flame-proof three-phase asynchronous motors have rated voltages of 380V, 660V, 380/660V, rated frequency of 50Hz, protection class of IP55, cooling method of IC411, Class F insulation, and full load temperature rise is assessed according to Class B. They are applicable to electric drive in coal mines (non mining working area) and workplaces containing explosive gas mixtures that meet the above standards. 

YB3 series Flameproof three-phase asynchronous motor is a new generation based on YB2 motor. It is a highly efficient motor popularized by the country. Features of high efficiency, low noise, small vibration, high locked rotor torque, reliable operation, beautiful appearance, etc. It is one of the important electrical products used in the petroleum, chemical and coal industries.

YB3 series flame-proof three-phase asynchronous motor has rated voltages of 380V, 660V, 380/660V, 660/1140V, rated frequency of 50Hz, protection grade of IP55, cooling method of IC411, Class F insulation, and full load temperature rise is assessed according to Class B.
