1 GENERAL
The FANUC AC servo motor αi series consists of a range of servo
motors that are suitable for the feed axes of machine tools. They have
the following features:
Excellent acceleration characteristics
The rotor inertia has been reduced without sacrificing maximum
output torque. As a result, the motors offer excellent acceleration
characteristics.
Compact
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.
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
The high-resolution pulse coder model α1000iA, α1000iI or α16000iA
is provided as standard. This pulse coder allows precise positioning.
Powerful brake
A powerful brake with an increased holding torque is available as an
option. The brake uses an asbestos-free design.
