FM7 MOTORS
GENERAL CHARACTERISTICS
These motors have been manufactured in accordance with the
European regulations EN 60204-1 and EN 60034 as instructed by
the European
D
irective 2014/35/EU on
L
ow
V
oltage (LVD).
The ’’F’’ classification of the winding insulation is based on its
capability to run at maximum temperature.
This temperature 155°C/311°F represents the maximum running
temperature for the winding. In other words, if the motor ran 40 hrs a
week in a clean and dry environment, its life expectancy would be 10
to 20 years before the insulation deteriorates due to the point that it
can no longer withstand the applied voltage.
TEMPERATURE SENSOR
The temperature sensor have a negative temperature coefficient
(NTC) and they should be used in control and measurement systems
within a range between -50°C (-58°F) and 200°C (392°F).
STRUCTURE
The structure of the motor is shown below.
TERMINAL BOX. LAYOUT OF THE CONNECTION TERMINAL
The layout of the terminals in the box on top of the motor depends on
the type of motor. The top image shows the terminal box on the
motor series FM7-
