IP Metric Motors Driving Industry World Over ISO 9001 CERTIFIED World Class Induction Motors
Long life features. Our experience has given us the knowledge to provide motors you can depend on and motors that last. Here are some of the features that set these motors apart. Premium insulation system. The insulation system has been designed to withstand a wide range of environmental conditions, thermal shock and voltage stress. Its non-hygro-scopic insulation components in the stator resist moisture and help prevent motor failure. Efficient cooling system. The cooler a motor runs, the longer its insulation will last. High airflow with an external fan on IP motors assure cool operation, low noise and increased motor life. Vacuum de-gassed, clean steel bearings. Bearings are anti-friction shielded with lithium-based grease. Pressure cast aluminum rotor. Pressure casting eliminates variations in bar and end ring resistance. It produces a rotor that gives more consistent performance. Heavy-duty stator frames and endshields. Cast iron construction of stator frames and endshields assures excellent corrosion resistance in most industrial environments. Parts are precisely machined to close tolerance and jig drilled to assure alignment, minimum vibration and ready interchangeability. Dynamically balanced rotor. Balance is critical to the life of the motor. The slightest deviation from the standard can result in excessive vibration which causes additional wear on the bearings and premature motor failure. To prevent this problem, precision electronic equipment is used to carefully balance every rotor and shaft assembly. Copper Windings. Heat and moisture resistant polyester enameled copper wire is used for all stator windings. Specially designed shaft. An endshield desgin that provides IP motor protection. It helps prevent contaminants from getting into the bearing. Easy access conduit box. The conduit box can be removed and rotated in 90 increments to facilitate installation with terminal board.
OXFORD Motors is proud to introduce the IP Metric Motor line of rugged, all-purpose motors. The cast iron, totally enclosed fan cooled IP construction makes this motor the preferred choice for almost any application in even the toughest environments. TYPICAL APPLICATIONS: Material handling Machine Tools Pulverisors Fans, Blowers Agro Industry Compressors Lifts Stone Crushers Pumps Valve Actuators Fertilizers Gear Drives Saw Mills Textiles Flour Mills Cranes Food Processing Granite / Marble / Stone Industry STANDARD RATINGS : 2 pole 0.-31Kw pole 0.-31Kw pole 0.-Kw pole 0.-0Kw pole.0-kw STANDARDS: Built to meet or exceed the IEC standards for dimensions and performance. IEC 3-1 Performance IEC 2D Dimensions IEC 3- Degree of Protection EFFICIENCY : Confirm to EFF-2 Level & are CE marked. POWER SUPPLY : For greater application flexibility and increased safety margin our motors are suitable for 1V +/-%, 0Hz+/-%, combined variation allowed +/-% AMBIENT TEMPERATURE : -1 to degree C is standard. SERVICE FACTOR : These motors have a 1.1 S.F. at 0Hz, typical for IEC motors, Duty class S1. CONSTRUCTION : The rugged cast iron construction of the frame, endshields, integral feet and flanges absorbs Shock and reduce motor vibration to provide a low-maintenance motor life. TERMINAL BOX : The terminal box is of cast iron construction and is available on Top. STATOR WINDING & INSULATION: The stator core is built up from low loss, high permeability, silicon steel for increased efficiency. It features a class F insulation system with design for class B maximum temperature rise. ROTOR : The rotor is built with the same high quality lamination steel,die cast with high conductivity aluminum, Shrunk fit on to a high strength carbon-steel shaft. The rotor assembly is dynamically balanced to Provide low noise and smooth, vibration-free operation for long trouble free life. BEARINGS : All motors use 0,000 hours direct coupled/2,000 hours belted, anti-friction, deep-grooved ball Bearings of 3 series, on drive & non drive end, tight fit in Frame & above COOLING METHOD: IC01 bi directional cooling fan. CONNECTION: Star-connection for up to 3Kw, delta-connection for Kw and above. WARRANTY: Oxford motors are warranted to be free from defects in material, workmanship for a period of one year.
