Our group will be working on the Comparative Motor Design project suggested by Prof. Krein for power department. The objective is to begin with a small commercial ac induction motor (our current selection is a 1/4 HP motor, Grainger #3N843) and design two improved rotor configurations that support comparative analysis in the lab. One rotor would be based on the commercial product, but would increase the amount of aluminum in the conductor bars to improve efficiency. The second would use copper in place of aluminum. Our team will develop analyze the two rotor designs, arrange for rotor fabrication, and then test all three rotors for dynamic and steady-state performance. We will also use finite element analysis software (e.g.ANSYS/Ansoft) to do the computer simulation comparisons for the designed rotors.

Project Description

Computed Tomography, often referred to as CT or CAT scans, is a modern technology used for medical imaging. While many people know of this technology, not many people understand how it works. The concepts behind CT scans are theoretical and often hard to visualize. Professor Carney has indicated that a small-scale device for demonstrational purposes will help students gain a more concrete understanding of the technical components behind this device. Using light rather than x-rays, we will design and build a simplified CT device for use as an educational tool.

Design Methodology

We will build a device with three components: a light source, a screen, and a stand to hold the object. After placing an object on the stand and starting the scan, the device will record three projections by rotating either the camera and screen or object. Using the three projections in tandem with an algorithm developed with a graduate student, our device will create a 3D reconstruction of the object.

Hardware

• Motors to rotate camera and screen or object

• Grid of photo sensors built into screen

• Light source

• Power source for each of these components

• Control system for timing between movement, light on, and sensor readings
