Recently,
on some treadmills the maximum continuous use time and the minimum
time needed to cool down the internal components of the treadmill are
shown on the label.
See,
for example, the label of this Weslo treadmill indicates an hour of
use and a pause time.
Unfortunately,
most of the treadmills do not give these indications. In addition,
there may be a significant difference due to:
• the
weight of the person using the tool (the higher the weight, the
greater the heat generated and the need for pauses),
• the
type of use, i.e racing or walking (less than 5 km / h), where -
contrary to common sense - the treadmill is heated and damages more
in the walk (for technical reasons related to the motor control
technology)
• the
conditions of the transmission elements (rollers, strap and belt). In
this regard, please note that a non-lubricated, too lubricated or old
belt can lead to a double current consumption compared to a new
low-friction type belt (buy low friction belts on the treadmill spare

A
much more precise and simple / economical solution to avoid damage to
the treadmill is to use a thermometer.
Just
place the sensor on the motor, fix it with a clamp, and you can
attach the small display to the treadmill uprights so that you can
check the temperature at any time. When this approaches 50 °C it is
necessary to stop training to cool down the motor. In fact, most
engines start a degradation process when the internal temperature
exceeds 100/120 °C. In fact, they start to dissolve parts of
isolation, and if you repeat this situation many times or continue
for a long time you may damage your motor very seriously.

Considering
that the outside temperature is about half of the inside, it is
understandable that under such conditions (ext. temperature over
45°C) the motor may be damaged.
You will notice that when the training was
interrupted, the motor temperature could rise for a few minutes
instead of going down. This is a natural effect because heat slowly
passes from the internal parts of the motor to the outer parts, thus
increasing the temperature on the outer surface.
In
practice, with a few euro investment you can avoid having to replace
the motor.
