GENERAL
The FANUC AC servo motor α series consists of a range of servo motors
that are suitable for the feed axes of machine tools. They have the
following features:
The rotor inertia has been reduced without sacrificing maximum output
torque. As a result, the motors offer excellent acceleration characteristics.
The use of the latest ferrite magnet, combined with an optimized
mechanical design, reduces both the overall length and weight. The result
is compact, lightweight servo motors.
The use of waterproof connectors and FANUC’s unique stator seal
provide excellent waterproofing, ensuring that no liquid, such as coolant,
can enter the motor.
The use of the latest servo software minimizes the heat generated by
high–speed rotation, allowing continuous operation over a wide range.
Further improvements have been made to the unique magnetic pole shape
to minimize torque ripple. The result is extremely smooth rotation.
The use of the latest servo software maintains controllability even when
a disturbance occurs.
The high–resolution pulse coder model αA1000, αA64 or αI64 is
provided as standard. This pulse coder allows precise positioning.
A powerful brake with an increased holding torque is available as an
option. The brake uses an asbestos–free design.
