The motors in question are typically 12V DC motors that will be placed in cars (seats, windows, etc...). I have almost no control over their actual casting/parts manufacture--nor do I have much information from that department.
The motors use brushes, and yes, I agree that precision will...
This is true. Impacting small motors to align the bearings could decrease the life span of the motor, but is that enough to justify the cost increase in making more precise parts? From a cost analysis perspective, making more accurate parts costs more money than the potential loss of quality…...
This question is actually in reference to a question I read earlier.
During the manufacturing process of a DC motor the bearings cannot be aligned perfect every time... Because of the misalignment the resultant fricition created raises the current draw (increasing noise and vibration). An...
