GENERAL
The FANUC AC spindle motor αseries is ideal for CNC machine tool
spindles.
` The motor is compact, light–weight and furnished with digital control
for much higher performance.
` The motor inertia of the AC spindle motor is made smaller to shorten
the acceleration/ deceleration speed. Further, optimum control
enables highly efficient cutting.
` The motor incorporating a position coder required for synchronous
feed of the spindle and Z axis, so rigid tapping can be used.
` Improvement in machining of the motor housing enhances the
accuracy of the mounting part.
` Waterproof and pressure–proof design conforming to the international
standard (IEC) is employed to improve reliability and make it resistant
to most environments.
