- 115 -
1 GENERAL
The FANUC AC servo motor αiS series is best suited for the feed axis
of a machine tool with high speed and high precision or small
machine tool. It has the following features:
Excellent acceleration characteristics
A high maximum output torque and intermediate rotor inertia result in
excellent acceleration characteristics.
Compact
The use of the latest neodymium ferrite magnet further reduces the
size and weight of the servo motors. This produces a servo motor that
is sufficiently compact to allow its use in small machine tools.
Excellent waterproofing
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.
Extended continuous-operation
High-density winding, low iron loss by the optimum core shape, and
the use of the latest servo software reduce heat generation during
high-speed rotation to a minimum and allow a wide continuous
operating zone.
Smooth rotation
Further improvements have been made to the unique magnetic pole
shape to minimize torque ripple. The result is extremely smooth
rotation.
Controllability
The use of the latest servo software maintains controllability even
when a disturbance occurs.
High-performance sensor
High-resolution pulse coders α1000iA, α1000iI, or α16000iA is used
in the standard configuration, enabling precise positioning.
Powerful brake
A powerful brake with an increased holding torque is available as an
option. The brake uses an asbestos-free design.
