This is a Powerpoint presentation of the mechanical and electrical design and assembly work I did during the first half of the course to design and manufacture a brushless DC motor from scratch. This design incorporated validation methods such as physical test-model verification and virtual simulation using software like and . Since we also needed to assemble this motor by hand we incorporated DFA and DFM principles to push more ambitious goals.

As of mid-term demo day, March 2nd, we had demonstrated variable speed spinning under loaded and unloaded conditions with early iterations of a driver circuit and controls algorithm.

Single Phase Characteristics

  • At 12V current draw is 1.26A (we would expect this to decrease when motor is in motion)

  • At 15V current draw is 1.46A

  • At 17V the motor starts to bind (plastic bends st rotor contacts stator)
