Problems with my Motor

     Most of the building process was quick, and easily done. However there are a few problems I encounter even now:

1) Inconsistency

     My biggest problem is inconsistency. Due to the way that the brushes are done, the speed of the motor is very inconsistent. Often the commutator pushes and bends the brushes out of the way, blocking the contact between the two. This can severely change the power of the motor and how fast it spins, making the difference between a C- and an A+.

                 

2) Winding the spool

     Often when the toy car is being wound, the thread will wind itself off the spool and into the way of the brushes. This could be a serious problem if it tangles with anything important.
