CQR-16/56 Fagor Compact Drives and Motors Quick Reference. Ref.1910
Nameplate
The specifications label stuck on FKM1 servo motors supplied by
FAGOR offers the necessary data to identify the motor for the user.
FKM2/4/6/8 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 Directive 2014/35/EU on Low Voltage (LVD)
.
TEMPERATURE SENSOR
The motors in the FKM family ·except for the FKM1/9 series· have a
platinum Resistance Temperature Detector Pt1000·(Ro = 1000 ohms
at 0 °C), providing thermal protection for the motor. Provides great
linearity, speed and a temperature range between -200°C/-328°F
and +850°C/1562°F. Its use is recommended in control and
measurement systems. It has no polarity.

Holding brake Optional on all models
Feedback *
Sinusoidal encoder.
Incremental TTL encoder
* Sinusoidal encoder (FKM with “A” winding) and incremental TTL
encoder (FKM with “F” winding).

*** Only the FKM66.20A...-2 and FKM66.30A models offer the “with
fan” option.
WARNING. The ·F· class insulation on the motor keeps its
dielectric properties as long as the temperature does not
exceed 150°C/302°F for a cooling temperature of
40°C/104°F.
