Yxn Series High Efficiency Three Phase Induction Motors
Description:： 
Series Yxn motors are developed, designed and manufactured into total-enclosed self-fan-cool squirrel-cage high-efficiency three-phase induction motors lately by our company. The efficiency index of this series motors confirms to the energy-saving estimate value specified in GB18613-2002 Medium- and Small-sized Three-Phase Induction Motors Restriction Value of Energy Efficiency and Energy-Saving Estimate Value. This series motors have attained the certificate of energy-saving products issued by China Accreditation Committee of Energy-Saving Products according to CCEC/T14-2001 Medium- and Small-Sized Three-phase Induction Motor Technology Requirement for Energy-Saving Product. The efficiency indexes have reached or exceeded the those specified in EPACT of America and agreed perfectly the requirements that the induction motors exported to America should satisfy EPACT efficiency standard requirement specified by Energy Policy Cat of U.S.A.. For series Yxn high-efficiency motors, the efficiency indexes are increased about 3％ than those of series Y increased-safety motors and has reached 1990s international advanced level.
The output ratings and mounting dimensions of this series motors perfectly conform to the specifications specified in IEC publications and the correlation between them agrees basically with DIN 42673 and can be interchanged with series Y motors. This series motors are engineered with many remarkable features such as high efficiency, compactness, low noise, small vibration, large margin of temperature rise, safe operation and long life on permanence etc. The motors frame size H160 and above are provided with an attachment having the use to drain or replenish lubricating grease without stopping the motor. And the spaces for stator winding temperature detector and moisture resistance heat tracing are left for safe and reliable operation. The motors are easy to complete with export machinery and equipment and to supply as spare accessories in the import equipment.
For this series motors, power ranges are 0.55kw~315kw and frame size H80~355.
The protection degree of this series motors is not lower than IP54 for main enclosures and IP55 for terminal boxes. The cooling form is IC411. This series motors can be modified and manufactured into outdoor type (W type) and outdoor neutral chemical corrosion resistance type (WF1 type) according to customer's requirement.
