With over 100 years of experience in motor design and application, the Company is a premier supplier of AC and DC motors and generators. Ranging from fractional hp ratings to 100,000 hp, these high-quality machines are used to drive pumps, fans, compressors, rolling mills, grinders, crushers, and a variety of other rugged applications. Their motors and generators are utilized in petroleum, chemical, pulp, paper, mining, marine propulsion, steel, electric utility and other industries throughout the world. TECO and Westinghouse Electric established a joint venture relationship in 1988 and TECO purchased Westinghouse in 1995. Today, TWMC is in a unique position of being able to provide quality motors, generators, drives, and power solutions, all from our headquarters in Round Rock, Texas. This capability, combined with our global manufacturing resources, uniquely position the TECO-Westinghouse Motor Company to serve all our customer needs.
two magnetic fields that push or pull each other to make the armature rotate. Recording a winding resistance value on these components is a common practice during de-energized motor testing for trending or troubleshooting. When it comes to measuring winding resistance, remember our tip that smaller is bigger. The smaller the wire size the bigger the resistance. The rotating armature windings, connected to the commutator, are relatively large and in many industrial DC motors are form wound. The stationary series windings are randomly wound around the pole pieces and are also relatively large. By relatively large we mean that if you look at an individual strand of copper wire that makes up the armature or series winding, the diameter or circular mils of the strand is larger when compared to the shunt field windings. The shunt field windings are also randomly wound around the same pole piece as the series winding but consist of much smaller strands of wire when compared to the series and armature windings. Therefore, true to our tip, on smaller shunt field windings you would expect a bigger resistance reading. Having a basic understanding of these two components will make you more effective when analyzing the data received when performing a winding resistance test on a DC motor.
