TYPES OF MOTORS AND DESIGNATION
The types and specifications of αi series servo motors are described as follows.
Models
α1/5000i, α2/5000i, α4/4000i, α8/3000i, α12/3000i, α22/3000i, α30/3000i, and α40/3000i
Excellent acceleration characteristics
The rotor inertia has been reduced without sacrificing maximum output torque. As a result, the motors offer excellent acceleration characteristics.
This chapter describes the specifications and characteristics of FANUC AC servo motor αi series. First section describes the common specifications to all motors, and next section describes the individual specifications and characteristics in the form of data sheet.

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 PECIFICATIONS AND CHARACTERISTICS FANUC AC SERVO MOTOR αi SERIES B-65262EN/03
