Product description
Within the FANUC α range, A06B-0123-B675 has a stall torque of 3.0 Nm and a continuous RMS current of 4.6 A. The α3/3000 motor version has a rated speed of 3,000 min⁻¹. Torque generation is characterised by a torque constant of 0.65 Nm/A and a single-phase back-EMF constant of 23 V per 1,000 min⁻¹. Rotor inertia is 0.0014 kgm², with a mechanical time constant of 0.006 s and a thermal time constant of 45 minutes. The single-phase armature resistance is 0.57 Ω and static friction torque is 0.3 Nm. Mounting uses the square front flange. Variant code B675 defines the mechanical and feedback configuration: digit 6 identifies the straight keyed shaft with integrated holding brake, while digits 75 identify the αA64 absolute pulse coder. This coder provides 65.536 divisions per revolution. The holding brake has 8 Nm braking torque and is supplied with 90 V DC at a permissible deviation of ±10 percent. Current is no more than 0.4 A; response times are 70 ms for release and 30 ms for braking. The fully enclosed, naturally cooled motor housing corresponds to IC410 and IP65. The square flange measures 130 × 130 mm and the braked α3 version has an overall length of 253 mm. A motor mass of 8.0 kg plus about 2.3 kg for the brake gives an overall weight of approximately 10.3 kg.
