AC Motor

, YKS, YKK sequence medium and big high voltage cage three-section asynchronous motors have twelve heart heights from H355 to H1250. The firm adopts advanced technologies at house and overseas, through a mature and reputable design and generation program, and brings together the company’s a lot of a long time of medium and large high voltage The new sequence of goods created by the encounter of AC motor production have the positive aspects of high effectiveness, minimal sound, minimal vibration, large trustworthiness and practical installation and servicing.
The energy grade and set up dimensions of this series of motors comply with my country’s CZPTs and the CZPT CZPTtrotechnical Commission’s IEC CZPTs, and can be utilised as a complete set of export equipment and a substitute for imported items.
This series of motors can be utilized to generate various basic equipment such as followers, pumps, compressors and other mechanical products, and are broadly utilised in electric power, machinery, mining, metallurgy, petrochemical and other industrial and mining enterprises.

Four, technical attributes and framework variety
 4.one This collection of motors adopts a box framework, the body is welded from steel plates into a box condition, gentle excess weight, and good rigidity. A protecting top protect or cooler is installed on the leading of the motor to facilitate the warmth dissipation, installation and maintenance of the motor.
4.2 The stator adopts an external press-suit construction, and the stator and rotor are punched from lower-decline non-oriented chilly-rolled silicon steel sheets. The stator winding is created of F-class insulation substance, which has sturdy insulation endure voltage and anti-corona capability. The winding ends are reliably fastened and tied, and are taken care of with vacuum stress impregnation solvent-free paint (VPI) procedure, so the motor insulation functionality Superb and trustworthy, higher mechanical strength, robust dampness resistance and extended service life.
four.three The rotor cage bar can be manufactured of cast aluminum or copper in accordance to overall performance parameters or consumer demands. Amid them, the solid aluminum cage bar and the conclude ring are integrally cast by centrifugal to guarantee the mechanical energy and stop the cage bar from breaking in the course of the motor operation the copper bar rotor is made of large-quality copper content, and the cage bar is welded with the stop ring by intermediate frequency welding. The welding quality is great. High toughness, and by way of the fastening process in the groove, drastically lessen the phenomenon of broken copper bars.
four.4 The bearing adopts two varieties of rolling bearing and sliding bearing. It is established by the electricity and velocity of the motor. Its protection amount is IP44, IP54 or IP55. The rolling bearing is geared up with a non-stop oil injection and drainage system, which is straightforward for customers to use and preserve.
four.5 The primary junction box is put on the appropriate facet of the motor (seen from the extension stop of the principal shaft), or it can be placed on the still left facet in accordance to consumer requirements. Separate grounding terminals are offered inside and outside the house the junction box.
4.six In accordance to consumer needs, temperature measurement gadgets can be added to crucial elements these kinds of as stator windings and bearings to facilitate on-web site observation and remote checking to make certain risk-free and trustworthy operation of the motor.
five. Problems of use
five.one Ambient air temperature: -15 ºC~40ºC
5.two Altitude: not a lot more than 1000m
five.three Rated frequency: 50HZ, allowable frequency deviation ±2%
5.4 In the course of rated procedure, the allowable voltage deviation is ±5%. (It can run at ±10% beneath the situations of seven.three in GB 755)
