they contain moving parts intended to "drive" another mechanism to
accomplish their work, motors are often sources of unwanted noise
and vibration. They convert energy from potential to mechanical.
Noise and vibration coming from motors actually result in
inefficiency. In this sense, noise and vibration are a symptom of
energy loss in the transfer process.
Sometimes noise and vibration resulting from inefficiency is minor
and inconsequential. In micro applications where precision is
essential vibration may seriously impair performance. In larger
motors in industrial applications vibration may negatively impact
the driven machine's performance of work necessitating reduced
(throttled back) operation to deal with excessive vibration and
requiring shorter intervals between maintenance resulting in greater
In applications of a more widespread consumer nature the negative
impact of noise and vibration at the point of contact between the
offensive manifestations of motor energy inefficiency and those
individuals with whom it comes in contact in the environment may
cause sufficient customer dissatisfaction to result in loss of
business. Conversely, an approach touting an Acoustically
Intelligent(tm) product may provide the differentiation needed to
spur increased market share.
