Our professionals and engineers have 23 several years of Expertise in the Bearing Business. we source chromed bar and tubes for hydualic and pheumatic cylinders.
YTM, YMPS series of three-period asynchronous motors for coal mills are a new series of products deveXiHu (West Lake) Dis.Hu (West Lake) Dis.ed by our company using advanced EPT at home and overseas, through a experienced and reliable style and creation system combined with EPT’s more than sixty years of producing encounter in medium and massive high-voltage AC motors. It has the benefits of high effectiveness, lower sound, lower vibration, high dependability and handy installation and upkeep.
This sequence of motors are EPTly made for different coal mills in EPT stations, mining, metallurgy and other EPT, and can also be utilised to drive other mechanical tools with comparable traits.

4, technical qualities and framework type
four.1 This collection of motors have the qualities of large locked-rotor torque, big warmth potential, and protected and dependable performance.
4.2 This collection of motors undertake a box-type structure. The frame is welded into a box-kind with metal plates. It is ligEPT in weigEPT and excellent in rigidity. A protective best protect or cooler is installed on the best of the motor to faXiHu (West Lake) Dis.Hu (West Lake) Dis.tate motor warmth dissipation, set up and upkeep.
four.three The stator adopts an external press-fit framework, and the stator and rotor punching sheets are punched from minimal-decline non-oriEPTd cold-rolled silicon steel sheets. The stator winding is made of F-course insulating substance, which has strong insulation endure voltage and anti-corona capacity. The winding ends are reliably fixed and tied, and are handled with EPT pressure impregnation solvent-free paint (VPI) approach, with outstanding overall performance and mechanical power Higher, robust humidity resistance and EPT services life.
four.four This sequence of motor rotors can adopt solid aluminum or copper bar rotors according to functionality and user demands to make certain the large commencing functionality of the motor.
four.5 The bearing adopts two types of rolling bearing and sliding bearing. It is identified by the EPT and pace of the motor. Its security level is IP44 or IP54. The rolling bearing is outfitted with a non-end oil injection and drainage device, which is effortless for end users to use and keep.
four.six The major junction box is placed on the rigEPT facet of the motor (viewed from the prolonged end of the spindle), or it can be placed on the left aspect according to person demands. Different grounding terminals are presented inside and outside the junction box.
four.7 According to person requirements, temperature measurement gadgets can be included to EPTant areas such as stator windings and bearings to faXiHu (West Lake) Dis.Hu (West Lake) Dis.tate on-internet site observation and distant monitoring to ensure risk-free and dependable operation of the motor.
