Meaning of the
codes of the
mounting method
FKM synchronous servo motors are AC brushless
with permanent magnets.
They are ideal for any application requiring great
positioning accuracy. They have a uniform output
torque, high reliability and low maintenance.
They are designed to meet the IP 64 protection
standard and, therefore, they are immune to
liquid and dirt.
FKM2 FKM4 FKM6
IP 64 means that is protected against dust and against water jets. They have a
temperature sensor to monitor the internal temperature. They also carry an optional
electromechanical holding brake. They have rotating power and feedback connectors.
The F class isolation on the motor maintains the dielectric properties as long as the work
temperature stays below 150°C/302°F.
