A simple electrical motor has three components: windings, armature, and housing. These three components have reliabilities of .97, .992, and .999. There is no possibility of redundant parts. The motor must have an overall reliability of 0.980, according to the product line manager who will use the motor as an input. What would you do to redesign the motor to meet this specification? Discuss, including a recalculation to meet the standard.
Electrical Motor

Final Answer :
Since no backup is possible, individual components must be redesigned. The windings represent the weak link, and are the obvious choice. If only the windings are improved, their new reliability must be at least 0.980 / (0.992∗ 0.999) = 0.98889
