FKM1 SERVOMOTORS
GENERAL CHARACTERISTICS
These motors have been manufactured in accordance with the
European regulations EN 60204-1 and EN 60034 as instructed by the
European

oltage (LVD).
TEMPERATURE SENSOR
The FKM1 motor series has a PTC 111-K13-140 thermistor for the
thermal protection of the motor winding. This is the positive
temperature coefficient (PTC) and has no polarity.
OUTSIDE APPEARANCE
The following figure shows the location of the connectors for power
and motor feedback conection:
In the FKM1 series, the power connector and the feedback connector
are built into the end of the cables leaving through the gland from the
motor itself. The approximate length of these cables is 1 m. For this
series, it is not appropriate to consider rotating connectors.

Sensor connection
Feedback cable
Motor series
FKM1
The following figure shows the resistance of the sensor as a function of the
ambient temperature (average values). The wires of the temperature sensor
are included in the feedback cable.
WARNING.
Note that the corresponding cable must be
installed on each connector. Remember that each cable has
a specific flexibility and, therefore, when handling the
connector with the cable installed, its maximum bending
radius must not be exceeded.
