This report documents the design phases and fabrication of an expandable micro-motor DC drive system. This project illustrates that a flexible range of output power demands can be met from a small DC micro-motor drive unit with the use of power electronics.
In this project miniature DC micromotor drives, each capable of drawing up to 5.5 amps rated current (5 amps due to the utilization of a 5 amp fuse), were designed as card inserts that can be conveniently inserted in parallel in to a cardholder within the console. The “insert” feature allowed our console to successfully draw up to 5 amps times n number of card inserts while maintaining high efficiency, as testing and data analysis suggests.
