A06B is the general prefix for FANUC servo motor series.0147 stands for the A22 frame size, medium-inertia rotor design, and a rated speed of 2000 rpm.B175 represents a straight shaft with a keyway, a built-in holding brake, and an integrated Alpha A64 absolute encoder.#7008 denotes the factory’s standard sealed specification, with basic shaft sealing and environmental protection structure, suitable for general workshop conditions.

Rated output power is 3.8 kW.Rated operating speed is 2000 revolutions per minute.Rated supply voltage is three-phase 157 V AC.Rated working frequency is 133 Hz.Continuous rated torque is 22 Nm.Rotor inertia is classified as medium inertia.Encoder type is an Alpha A64 serial absolute encoder with a resolution of 65536 pulses per revolution.A built-in power-off holding brake is integrated inside the motor.Insulation grade is Class F, with a maximum allowable temperature of 155 degrees Celsius.Cooling method is natural air cooling via surface heat dissipation.Stall torque remains 22 Nm under locked-rotor conditions.Rated working current is 15 A, and stall current is 19 A.

The motor adopts a standard flange mounting structure with a square flange installation design.Positioning spigot and mounting hole positions follow standard A22 frame dimensions.Shaft structure is a straight shaft with a standard keyway; the #7008 configuration uses a standard shaft lip seal to prevent oil mist and dust from entering the motor interior.The motor has a compact overall structure, incorporating high-precision bearing assemblies and an integral cast aluminum housing, ensuring high rigidity and low-noise operation.The approximate net weight of the motor is 29.5 kilograms.

The protection grade of this model is IP54 under the #7008 specification, providing good dust-proof and splash-proof capabilities.Allowable operating ambient temperature ranges from 0 degrees Celsius to 55 degrees Celsius.Storage ambient temperature ranges from minus 20 degrees Celsius to 70 degrees Celsius.Relative humidity of working and storage environments is 10 percent to 90 percent, with condensation prohibited.It can operate normally at altitudes below 1000 meters above sea level.Allowable mechanical vibration level is up to 5G, adapting to machine tool cutting vibrations and frequent dynamic operation.

Medium-inertia rotor design balances dynamic response speed and load operation stability, suitable for frequent start-stop, forward-reverse switching, and variable-load processing.Built-in Alpha A64 absolute encoder enables high-precision position detection, eliminating the need for an external battery to maintain absolute position data and supporting direct power-on operation without a reference point.Built-in holding brake provides reliable power-off locking, ensuring safety for vertical axis and suspended load applications.Standard sealed structure of #7008 isolates common dust and coolant splashes, meeting general workshop environmental requirements.Natural air cooling structure without a fan reduces failure points and maintenance efforts, suitable for long-term continuous operation.High-rigidity housing and precision bearing matching ensure low noise, low vibration, and stable speed accuracy during high-speed operation.The motor is fully compatible with FANUC Alpha i-B series servo amplifiers, supporting direct replacement, matching parameters, and convenient installation and debugging.

Cut off all power supplies to the motor and driver before any installation, wiring, or maintenance work.Adopt flange-fixed installation, mounting the motor horizontally or vertically on the mechanical mounting surface, and tighten the four fixing bolts evenly to ensure installation flatness and assembly concentricity.Select a suitable coupling to connect the motor shaft and mechanical load, strictly controlling the coaxiality of the shaft connection to avoid eccentric loads causing vibration, noise, and premature bearing damage.Do not apply heavy impact hammering to the motor shaft end, and do not subject it to excessive radial and axial external loads beyond the allowable range.Use original FANUC matched shielded power cables and encoder cables for wiring. Arrange wiring reasonably, maintain a sufficient bending radius, and avoid crossing or parallel laying with high-voltage power lines.Fasten all connectors firmly and ensure plug sealing to maintain the overall protection performance of the #7008 specification.Make a reliable grounding connection for the motor shell to prevent electric leakage and interference affecting positioning accuracy.

Do not operate the motor for extended periods exceeding the rated voltage, speed, and torque to avoid motor overheating, permanent magnet demagnetization, and insulation aging damage.This motor has a built-in holding brake, but regular inspection of brake performance is required for vertical axis use to prevent load sliding due to brake failure.Do not use the motor in environments with explosive gas, strong corrosive liquid, or a large amount of conductive dust.It is forbidden to disassemble the motor shell, encoder, or internal structure without authorization. Unauthorized disassembly will damage sealing performance and void the product warranty.Immediately stop operation and cut off the power supply if abnormal noise, obvious vibration, housing overheating exceeding 80 degrees Celsius, or servo alarms occur during operation. Check the fault cause after cooling down.Avoid long-term frequent jogging forward and reverse to reduce current impact and thermal accumulation on the motor.

Regularly keep the motor surface clean by removing dust, oil, and iron filings to ensure smooth surface heat dissipation and unobstructed ventilation areas.Periodically check the tightness of mounting bolts, coupling locking status, and cable connector firmness, and tighten loose parts promptly.Internal motor bearings adopt factory permanent lubrication design, requiring no regular oiling. Replace bearings promptly if abnormal operating noise and vibration occur.Regularly check the sealing status of the shaft end and connectors to maintain the IP54 protection performance of the #7008 standard specification.When the motor is stored idle, place it in an indoor dry, clean, and ventilated environment with ambient temperature maintained between 5 degrees Celsius and 35 degrees Celsius, and relative humidity not exceeding 85 percent without condensation.Keep the original packaging during storage to avoid direct sunlight, moisture immersion, and heavy pressure stacking.
