INTRODUCTION
FXM series synchronous servo motors
are AC Brushless, with permanent
magnets.
They are ideal for any application
requiring great positioning accuracy.
They have a smooth torque output, has
no brushes, high reliability and low
maintenance.
Brushless AC Motors, FXM
- Meaning of the
mounting codes.
- IP64 means that it is protected against dust and against
water jets.
- The F class isolation on the motor maintain the dielectric
properties as long as the work temperature stays below
155°C (311°F).

FXM5
FXM7
Its normal protection level
is IP64, being immune to
liquids and dirt.
The system incorporates a
temperature sensor for
monitoring the internal
temperature. They also
carry an optional
electromechanical brake.
