Uneven surface deflection and amplitude measurement tool

A system for measuring a deflection of a ripple spring in a stator core winding slot from a free-state of the ripple spring, the system comprising,

• a frame slidingly supporting a set of pins, each pin individually spring biased to engage the ripple spring, each pin including a high point stop and a low point stop fixedly coupled thereto,
• a low point isolator member moveable relative to the frame, the low point isolator member indicating a lowest point of the ripple spring engaged by the set of pins based on engagement of the low point isolator member by a respective low point stop of a first pin in the set of pins that engages a low point of the ripple spring;
• a high point isolator member moveable relative to the frame, the high point isolator member indicating a highest point of the ripple spring engaged by the set of pins based on engagement of the high point isolator member by a respective high point stop of a second pin in the set of pins that engages a high point of the ripple spring;
• a low point displacement sensor fixedly coupled to the frame, and having a sensor tip engaging the low point isolator member for identifying a low point displacement;
• a high point displacement sensor fixedly coupled to the frame, and having a sensor tip engaging the high point isolator member for identifying a high point displacement;
• and
• a calculator for calculating a difference between the low point displacement and the high point displacement, the difference indicative of the deflection of the ripple spring.

A probe assembly for measuring an amplitude of an uneven measurement surface, the probe assembly comprising;

• a frame slidingly supporting a set of pins, each of the set of pins being individually spring biased to engage the uneven measurement surface, each pin including a high point stop and a low point stop fixedly coupled thereto;
• means for sensing a low point displacement at a low point of the uneven measurement surface and a high point displacement at a high point of the uneven measurement surface based on a location of two of the set of pins;
• and
• a calculator for calculating a difference between the low point displacement and the high point displacement, the difference indicative of the amplitude of the uneven measurement surface.
