Founded in 1995, China Dongda Power Industry Co., Ltd. is one of the few asynchronous motor manufacturer and distributor in China that has patents on the generator, motor, power supply, engine, alternator, diesel and gearmotor design, supply and sale. Our custom asynchronous motors has obtained the certifications of ISO9001-2000, GS/TUV, CE, VL, EPA, QHS, SON, CAP and SRS and we have won EPA 2005 Motor Year Certification. Our 30 QC staff carefully performs inspections at every stage of production, from the time we receive raw materials to packaging. Noise, power, and stability are tested to ensure that our engines can endure 580 hours of constant use. We also can design and deliver OEM/ODM samples in one month.

YDseries single-phase and three-phase variable pole multi-speed asynchronous motors are the derived productsof Y, YL series(IP44) asynchronous motors. The installment and exterior dimension. Insulation grade, protection grade, cooling method and using condition of the YDseries single-phase amd three-phase variable pole multi-speed asynchronous motors are all the same as those of the Y series(IP44) motors. The relation between the frame number amd speed ratio and powerand perform ance index are comtiguous with the advanced level of the same international products. They have the advantages of high electrical efficiency, good start performance, low noise, small vibration and being easy to use and maintain etc.

Y serles motors is a kind of low-voltage three-phase asynchronous motor, Which is a basic series for general uses. This series can meet requirements for general uses at home and abroad with frame range 80-315. Y series has the advantages of high efficiency, energy saving, fine operation performance, small vibration, low noise, long serviced life, high reliability, convenient maintenance, big breakaway torque, Fixing measurement and power grade completely conform to IEC standard. It employs Grande B insulation. Lp44 class for shell protection and lc411 cooling mode. The rated voltage and frequency of series are respectively 380V and 50Hz. Y connection is adopted for motors below 3KW and connection is adopted for those above 4KW. Y series motor is commonly applied in machinery and equipment without special requirements, such as agricultural machinery, food machinery, fan, agitator and air compressor, etc.
