Fanuc aIF 12/4000 A06B-0243-B605#S000 3000 RPM AC Servo Motor with Pulsecoder aiAR128 Technical Overview

The Fanuc aIF 12/4000 A06B-0243-B605#S000 is a compact AC servo motor designed for precision motion control in industrial automation. It delivers a continuous rated speed of 3000 RPM and provides smooth torque delivery at varied loads. The motor housing is built from die-cast aluminum for a balance of strength and light weight. It has a flange size that fits standard servo mounts and easily integrates into existing robotic or CNC systems. The motor’s shaft is ground and hardened to resist wear and maintain alignment over long service intervals. The winding is insulated with class H material to tolerate elevated temperatures. The unit uses sealed bearings that retain lubrication and keep out dust and moisture. This construction helps the motor run quietly and consistently, even under heavy use.

The key feature of the aIF 12/4000 is the built-in aiAR128 pulsecoder. This encoder provides 131 072 pulses per revolution, which gives high resolution position feedback. The pulsecoder uses a sin/cos analog output that drives Fanuc servo amplifiers to achieve accurate speed and position control. The encoder’s optical scanning method ensures low noise and minimal error. It is mounted directly on the motor shaft and sealed to IP65 rating. This sealing prevents contaminants from affecting the encoder’s operation. The pulsecoder connects via a shielded cable that reduces electromagnetic interference. The motor cable assembly uses a flexible PVC jacket that resists oil and abrasion. The connector is keyed to prevent miswiring and features a latch to keep the connection secure.

This servo motor runs on standard Fanuc A06B-compatible drives and accepts power up to 230 VAC three-phase. It draws up to 4.0 A at full load and offers a peak torque of 1.2 Nm. The continuous torque rating is 0.6 Nm, which suits light to medium-duty applications. The motor’s insulation and bearing design allow it to work in temperatures from 0 °C to 55 °C without derating. It also handles up to 95 % relative humidity at 40 °C. The rotor assembly is balanced to ISO G 2.5 standards to keep vibration levels low. The shaft end includes a keyway for direct coupling to gears or pulleys. The back end plate has mounting holes for optional brake assemblies. The motor weight is approximately 1.2 kg, making it easy to handle during installation or maintenance.

Industrial News

Recent automation trends show a growing demand for servo motors with integrated encoders like the aIF 12/4000. Manufacturers are upgrading legacy systems to deliver tighter motion control and faster cycle times. New production lines in the automotive and electronics sectors push for higher throughput with minimal downtime. Servo motors that combine motor and encoder in one compact package help reduce installation errors and speed up commissioning. They also cut down on cable runs and simplify wiring layouts, which lowers installation costs.

Another trend is the move to predictive maintenance in servo systems. Users now fit motors with monitoring modules that track vibration, temperature, and encoder signals in real time. These data streams feed into analytics platforms to predict bearing wear or winding insulation failure before a breakdown occurs. This approach extends equipment life and reduces unplanned stoppages. The Fanuc aIF 12/4000 series is compatible with such monitoring add-ons and can integrate smoothly with condition monitoring networks.
