Vertical Coal Mill Motor, Three Phase AC Asynchronous Motor

Vertical Coal Mill Motor, Three Phase AC Asynchronous Motor

I. Overview
YLTM, YLMPS sequence of three-section asynchronous vertical motors for coal mills are a new series of merchandise produced by our company using advanced technologies at residence and overseas, by means of a experienced and reliable style and manufacturing technique combined with the firm’s more than sixty many years of manufacturing knowledge in medium and big higher-voltage AC motors. It has the positive aspects of higher efficiency, low sound, reduced vibration, higher trustworthiness and practical installation and maintenance.
  This sequence of motors are specifically developed for different coal mills in energy stations, mining, metallurgy and other industries, and can also be used to drive other mechanical tools with comparable qualities.

4, specialized traits and composition kind
4.1 This sequence of motors have the traits of large locked-rotor torque, large heat potential, and risk-free and trustworthy performance.
four.two This collection of motors undertake a box-sort composition. The body is welded into a box-variety with steel plates. It is gentle in excess weight and excellent in rigidity. A protective leading protect or cooler is mounted on the top of the motor to aid motor heat dissipation, set up and servicing.
four.three The stator adopts an exterior press-suit composition, and the stator and rotor punching sheets are punched from minimal-decline non-oriented cold-rolled silicon steel sheets. The stator winding is made of F-class insulating substance, which has robust insulation endure voltage and anti-corona capability. The winding ends are reliably fixed and tied, and are handled with vacuum pressure impregnation solvent-cost-free paint (VPI) approach, with exceptional overall performance and mechanical strength Large, strong humidity resistance and long provider lifestyle.
four.4 This sequence of motor rotors can undertake solid aluminum or copper bar rotors in accordance to performance and user requirements to make certain the large starting overall performance of the motor.
four.5 The bearing adopts two kinds of rolling bearing and sliding bearing. It is determined by the electricity and pace of the motor. Its defense level is IP44 or IP54. The rolling bearing is geared up with a non-quit oil injection and drainage device, which is straightforward for users to use and sustain.
4.six The primary junction box is positioned on the proper aspect of the motor (viewed from the extended conclude of the spindle), or it can be placed on the remaining aspect in accordance to user requirements. Individual grounding terminals are presented inside of and outside the junction box.
4.seven In accordance to user specifications, temperature measurement gadgets can be extra to critical parts these kinds of as stator windings and bearings to aid on-website observation and remote monitoring to guarantee secure and dependable procedure of the motor.

5. Conditions of use
five.1 Ambient air temperature: -25ºC~50ºC
5.2 Altitude: not much more than 1000m
five.3 Rated frequency: 50Hz, allowable frequency deviation ±1%
five.four In the course of voltage procedure, allowable voltage deviation ±5% (it can operate at ±10% below the situations of 7.three in GB 755)
