Motor
treadmill assembly
In
this example, we see one of the errors that can occur when mounting a
treadmill motor.
As
you can see from the picture the customer has inadvertently mounted
the motor misaligned with respect to the roller pulley. In this
configuration the drive belt will not work correctly.
Although
the belt has some play and can recover imperfect alignments, if the
misalignment is excessive two effects will occur:
1)
the belt will tend to come out of the pulley during use
2)
if you stretch the belt a lot to prevent it from slipping, it will
apply a tangential force on the bearings of the pulleys (roller and
motor) and this could lead to noise
Other
possible errors in the installation of a replacement engine:
1)
too long screws. If the screws are too long and enter too much into
the motor, this can lead to several problems. The screws must simply
be screwed into the outer frame of the motor. This problem can be
avoided by using simple washers;
2) drill the motor: the motor must never be
drilled. If the holes on it do not correspond to those on the
treadmill bracket, it is necessary to drill the bracket (which is
much simpler and safer). There are also motor clamps that allow you
to fix the motor in position without the need to make holes, you can
buy them here: motor clamps for treadmills
3)
tensioning the motor belt too much: over tensioning the belt (or the
running belt) is always an error and causes premature wear of the
components. The tension must be the minimum necessary to ensure that
the user cannot slip during the exercise and must not go further.
4)
forget to do maintenance and monitor the motor during the first use:
replacing the motor may not be a simple operation and the failure of
the old motor could be due to some forgetfulness in periodic
maintenance or some other component (e.g. running tape) that requires
maintenance or replacement. How can you prevent the newly purchased
motor from melting like your old motor?
It's
easy, you have to measure "the fever" (especially during
the first training sessions)
If
the outer casing of the motor reaches 45 ° C during training or
exceeds it, it means that additional maintenance is necessary. If you
do not have a specific thermometer, you can simply (carefully) place
your hand on the motor at the end of training, if the temperature is
too high, it will not be possible to keep the hand on the motor
because it will be too "hot".
If
the temperature is abnormal, please first proceed with a cleaning and
maintenance cycle, using appropriate lubricants. See the directions
on our blog for the best tips.
If,
despite the cleaning and lubrication, the motor continues to heat,
the problem may lie in the deck, which must be straight and not have
any hollows, or in some mechanical problem, but most frequently it
concerns the running belt, especially if the belt is older than 5
years. By replacing the belt with a low-friction tape for treadmills,
you will almost always solve the problem. If you purchased the motor
at our treadmill spare parts e-shop and need more parts to complete
the repair, please contact our customer care to get a special
discount that will make your repair convenient.
