A new measurement process and tool is to be developed to improve the existing method for measuring runout on the commutators of brushed DC product.
After an armature is manufactured, the commutator is inspected by placing the completed rotor assembly in one of several non-standard measurement fixtures. An indicator is then positioned on the commutator. A trained operator proceeds to rotate the armature while taking runout and bar-to-bar measurement at various positions along the length of the commutator.
This existing process is slow, costly, and unreliable. For these reasons, there is substantial economic pressure to develop a superior method for …

There is a system efficiency lab that sits in the thermodynamics lab of the Mechanical Engineering Technologies department. To expand this lab, a torque measuring device was needed to measure the torsional force that the pump exerts on the air motor. The expansion of this lab is important to give a better understanding of how the different mechanical parts effect the efficiency of the overall system. The first step in the expansion process was the design of a suitable torque measuring device. The most efficient design was a simple one with minimal moving parts. When the air motor is energized …
