Three Phase Induction Electric Motor

Three Phase Induction Electric Motor

YX, YXKS, YXKK collection of medium and large substantial-effectiveness high-voltage cage a few-period asynchronous motors have a overall of forty center heights from H90 to H1250. Our company has adopted present day innovative analysis technology, blended with our firm’s a long time of expertise in developing and manufacturing motors. Estimate and optimize the style of a variety of losses, wind resistance of each wind route, and toughness of every single element. The use of large-top quality components and scientific processing engineering in the manufacturing makes the series motors have the rewards of higher performance, lower sounds, lower vibration, substantial reliability and handy installation and upkeep.
The performance indicators of this collection of merchandise comply with the restrictions of the Ministry of Finance and the Nationwide CZPT and Reform Fee on the “Implementation Policies for the Marketing of Motors in Universities and Colleges for Power-preserving Items Benefiting Tasks”.
This sequence of motors can be employed to push different common equipment this sort of as fans, pumps, compressors and other mechanical gear, and are extensively used in electric powered energy, machinery, mining, metallurgy, petrochemical and other industrial and mining enterprises.

4, technical characteristics and composition sort

four.1 This collection of motors undertake a box composition, the body is welded by metal plates into a box variety, gentle weight, excellent rigidity, the leading of the motor is outfitted with a protecting top protect or cooler, which is handy for motor heat dissipation, installation and routine maintenance.
4.two The stator is made of large-good quality low-decline silicon steel sheets laminated in sections to ensure the quality of the iron main, so as to minimize iron main decline and improve effectiveness. The stator winding is created of F-course insulating material, which has strong insulation withstand voltage and anti-corona ability. The winding finishes are reliably mounted and tied, and vacuum stress impregnation solvent-free of charge paint procedure (VPI) is utilized, so the motor’s insulation performance Outstanding and trustworthy, substantial mechanical toughness, strong dampness resistance and lengthy provider lifestyle.
four.3 Our business styles a enthusiast dimensions in the very same center, higher and the very same pole variety in accordance to one-two electricity data files, every single supporter calculates the air inlet and outlet angles in element, and utilizes Ansys to evaluate the partial stress air quantity of each and every section of the air duct, and design and style a affordable air duct The distribution and number of air ducts strictly handle the wind friction of the motor.
4.four The use of copper row rotors can successfully minimize extra stray losses and lessen rotor bar losses.
4.5 Through the German LDW motor large-electricity and substantial-performance motor technology transformation function, the slot-piece optimized framework is adopted, the air path is optimized, and the overall wind resistance of the motor is diminished to minimize the general wind path loss.
four.6 The bearing adopts two sorts of rolling bearing and sliding bearing. It is decided by the electrical power and velocity of the motor. Its protection degree is IP44, IP54 or IP55. The rolling bearing is geared up with a non-quit oil injection and drainage system, which is straightforward for users to use and maintain.
4.7 The main junction box is put on the right aspect of the motor (seen from the extension finish of the main shaft), or it can be placed on the left side according to consumer demands. Independent grounding terminals are supplied inside and outside the house the junction box.
four.8 In accordance to consumer demands, temperature measuring devices can be included to important areas these kinds of as stator windings and bearings to aid on-website observation and distant monitoring to guarantee protected and reputable operation of the motor.

five. Problems of use
5.one Ambient air temperature: -25ºC~50ºC
five.2 Altitude: no far more than a thousand m
5.3 Rated frequency: 50Hz, allowable frequency deviation ±1%
five.4 During voltage procedure, the allowable voltage deviation is ±5%. (It can operate at ±10% below the condition of seven.3 in GB 755)
