1 IP Metric Motors Driving Industry World Over ISO 9001 CERTIFIED World Class Induction Motors

2 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.

3 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.
