Y2dt Series Pole-Changing Multi-Speed Three Phase Asynchronous Motors

Product Description  General Introductions Y2DT series multi-speed three-phase asynchronous motors are the derivatives of Y series three-phase asynchronous motors. While learning from the merits of foreign similar motors, our company independently designed and developed the motors. The motors mainly for drive blowers and pumps,and other properties conform to the specifications of IEC standards.Structure Declaration  The products are asynchronous pole-varying speed control motors, which change the number of poles, pairs in stator rotating magnetic field by changing the connection mode of stator windings and thus realize speed control. Speed changing principle of the multi-speed motors: speed control is realized by changing the connection mode of stator windings, namely, changing the number of pole pairs in the motor* s rotating magnetic field. The multi-speed motors (fans) operate at low speed at ordinary times and could turn to high-speed mode sometimes. The switch between the following external control circuits is mainly used to change the connection mode of stator windings.   1. Two shared windings with different numbers of pole-pairs are embedded into the stator slots, and the number of pole-pairs is changed by varying the connection mode of stator windings through the switch between external control circuits; 2. Two independent windings with different numbers of pole-pairs are embedded into the stator slots;  3. Two independent windings with different numbers of pole-pairs are embedded into the stator slots, The motors can meet both domestic and foreign demands for general use. The frame size range is 80-280. This product series adopts a unified design in China.  The motors have the advantages of high efficiency, energy saving, low vibration and noise, long lifespan, high reliability, high-temperature resistance, and excellent starting and operating performance. The mounting dimensions and output ratings conform to the specifications of IEC standards.Work Conditions      Rated voltage: 380V Output power: 0.17KW-160KWPoles:2/4,4/6,6/8,4/6/8Protection class: IP44Insulation class: F,H temperature rise BAltitude: Not exceed 1000m metersRated frequency:50HzDuty: Continuous(S1)Ambient temperature: -15ºC~+40ºC The Above Is The Default Parameters,if You Have Any Other Special Requirements,you Can Contact Us For Customization.TECHNICAL DATA (50HZ)  TypePoleOutput (kW)Rated Current (A)Speed r/minEff %ηPower FactorΦLocked Rotor Torque Rated TorqueLocked Rotor Current Rated CurrentMax Torque Rated TorqueTst/Tn   Ist/In Tmax/TnSynchronous Speed 1500/3000rpmY2DT80M1-4/240.170.71420580.621.45.51.820.7522860680.8227.51.8Y2DT80M2-4/240.250.91420640.651.45.51.820.952.52860700.8127.51.8Y2DT90S-4/240.30.91430700.721.45.51.821.43.72850710.8227.51.8Y2DT90L-4/240.41.21430720.731.45.51.821.94.52850750.8627.51.8Y2DT100 L1-4/240.651.91430740.721.45.51.822.55.32850820.8727.51.8Y2DT100L2-4/240.82.21430760.721.45.51.823.16.62850820.8727.51.8Y2DT112M-4/241.12.81450800.741.45.51.824.49.32890820.8827.51.8Y2DT132S-4/241.43.61450800.741.35.51.825.911.92860830.911.97.51.8Y2DT132M-4/2424.81450830.771.35.51.82815.72880850.911.97.51.8Y2DT160M-4/242.86.71460850.751.35.51.8212.524.32920860.911.97.51.8Y2DT160L-4/243.88.81460860.761.35.51.821630.72920870.911.97.51.8Synchronous Speedl 000/1500rpmY2DT90S-6/460.321.2920630.661.661.841.13.11420700.781.871.8Y2DT90L-6/460.451.5930680.661.661.841.43.61400720.811.871.8Y2 DT100 L1-6/460.72.2940730.661.661.842.25.31440800.791.871.8Y2DT100L2-6/460.92.8940740.671.661.842.561440810.781.871.8Y2DT112M-6/461.13.2960780.681.661.843.27.21440820.821.871.8Y2DT132S-6/461.54.1970810.681.661.844.710.21440840.831.871.8Y2DT132M-6/462.25.8970830.691.661.846.714.11440850.851.871.8Y2DT160M-6/463.18.2970830.691.671.849.519.81460870.841.87.51.8Y2DT160L-6/46410.6970830.691.671.841224.71460880.841.87.51.8     Company Profile Company ProfileVisionWith decades of rapid development and accumulation, China has been perfect and mature on technology and management in various industrial areas, shaping a complete processing manufacturing industry with competitive price, well known for its excellent skill, high efficiency and hardworking team with qualification for personnel dispatching.At the time of economic globalization, it is our consistent target and objective to integrate and export all kinds of technology, management mode, engineering project and manpower as per the actual requirement of our client With our own abundant technical strength, superior integration capability of technology and resources, well experienced of project implementation and management as basis and platform;Let China go out to the world, and make the world know of China; ProfessionalProfessional technical and management team with abundant experience in the implementation of domestic and international projects;ResponsiveResponsively and meticulously, translating your needs into complete solutions;IntegrationIntegrating various technologies and resources in
