GENERAL
The FANUC AC servo motor αM series is suitable for application to the
feed axes of small machine tools. It has the following features:
A high maximum output torque and intermediate rotor inertia result in
excellent acceleration characteristics.
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.
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.
High–resolution pulse coder αA1000, αA64, αI64 is used in the standard
configuration, enabling precise positioning.
A powerful brake with an increased holding torque is available as an
option. The brake uses an asbestos–free design.
The types and specifications of αM series servo motors are described as
follows.
The αM series includes the following models:
D Models αM2 and αM2.5 (excluding shaft type models) that are
compatible with the installation dimensions of the α series models α1
and 2.
D Models αM3, αM6, and αM9 that are compatible with the installation
dimensions of the α series models α3 and 6.
D Models αM22 and αM30 that are compatible with the installation
dimensions of the α series models α12, 22, and 30.
