A06B is the general prefix of FANUC servo motor series.0147 stands for A22 frame size, medium inertia rotor design and rated speed 2000rpm.B075 represents straight shaft with keyway, no holding brake and built-in Alpha A64 absolute encoder.#7076 indicates factory special sealed specification, improved shaft sealing and overall environmental protection structure, adapting to harsh workshop working conditions.

Rated output power is 3.8kW.Rated operating speed is 2000 revolutions per minute.Rated supply voltage is three phase 157V AC.Rated working frequency is 133Hz.Continuous rated torque is 22Nm.Rotor inertia belongs to medium inertia grade.Encoder type is Alpha A64 serial absolute encoder with resolution 65536 pulses per revolution.There is no built-in power off holding brake inside the motor.Insulation grade is Class F with maximum allowable temperature 155 degrees Celsius.Cooling method is natural air cooling by surface heat dissipation.Stall torque keeps 22Nm under locked rotor condition.Rated working current is 15A and stall current is 19A.

The motor adopts standard flange mounting structure with square flange installation mode.Positioning spigot and mounting hole position adopt standard A22 frame dimension.Shaft structure is straight shaft with standard keyway, and #7076 configuration adopts reinforced shaft lip seal to prevent oil mist and dust from entering the motor interior.Motor overall structure is compact, with high precision bearing assembly and integral cast aluminum housing, ensuring high rigidity and low noise operation.The approximate net weight of the motor is 29.5 kilograms.

Protection grade of this model is IP54 under #7076 specification, with good dust proof and splash proof capability.Allowable operating ambient temperature ranges from 0 degree Celsius to 55 degree Celsius.Storage ambient temperature ranges from minus 20 degree Celsius to 70 degree Celsius.Relative humidity of working and storage environment is 10 percent to 90 percent, and condensation is not allowed.It can be used normally at altitude below 1000 meters above sea level.Allowable mechanical vibration level is up to 5G, adapting to machine tool cutting vibration and frequent dynamic operation.

Medium inertia rotor design balances dynamic response speed and load running stability, suitable for frequent start stop, forward reverse switching and variable load processing.Built-in Alpha A64 absolute encoder realizes high precision position detection, no need for external battery to maintain absolute position data, and supports power on direct reference free operation.Reinforced sealed structure of #7076 effectively isolates oil mist, dust and cooling liquid splash, improving reliability and service life in harsh workshop environment.Natural air cooling structure without fan reduces failure points and maintenance work, suitable for long time 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 supply of motor and driver before any installation, wiring and maintenance work.Adopt flange fixed installation mode, install the motor on the mechanical mounting surface horizontally or vertically, and tighten the four fixing bolts evenly to ensure installation flatness and assembly concentricity.Select suitable coupling to connect motor shaft and mechanical load, strictly control coaxiality of shaft connection, avoid eccentric load causing vibration, noise and premature bearing damage.Do not apply heavy impact hammering on the motor shaft end, and do not bear excessive radial and axial external load beyond the allowable range.Use original FANUC matched shielded power cable and encoder cable for wiring construction. Arrange wiring reasonably, keep enough bending radius, avoid crossing and parallel laying with high voltage power lines.Fasten all connectors firmly and keep the plug sealed well to maintain the overall protection performance of #7076 specification.Make reliable grounding connection for motor shell to prevent electric leakage and interference affecting positioning accuracy.

Do not make the motor run for a long time exceeding rated voltage, rated speed and rated torque, so as to avoid motor overheating, magnetic steel demagnetization and insulation aging damage.This motor has no built-in holding brake, so it is not allowed to be used alone on vertical axis and suspended load mechanism. External mechanical locking device must be configured to prevent load sliding and falling when power is off.Do not use the motor in explosive gas, strong corrosive liquid and environment with a large amount of conductive dust.It is forbidden to disassemble the motor shell, encoder and internal structure without authorization. Private disassembly will damage the sealing performance and void the product warranty.Stop running immediately and cut off the power supply once abnormal noise, obvious vibration, shell overheating exceeding 80 degrees Celsius or servo alarm occurs during operation, and check the fault reason after cooling down.Avoid long time frequent jogging forward and reverse, reduce current impact and thermal accumulation of the motor.

Keep the motor surface clean regularly, remove dust, oil dirt and iron filings, ensure smooth surface heat dissipation and no blockage of ventilation area.Regularly check the tightness of mounting bolts, coupling locking state and cable connector firmness, and tighten loose parts in time.Motor internal bearings adopt factory permanent lubrication design, no regular oil filling is required. Replace bearings in time if abnormal running noise and vibration appear.Check the sealing state of shaft end and connector regularly to keep the IP54 protection performance of #7076 sealed specification.When the motor is stored idle, place it in indoor dry, clean and ventilated environment, with ambient temperature kept between 5 degrees Celsius and 35 degrees Celsius, and relative humidity not higher than 85 percent without condensation.Keep the original packaging state during storage, avoid direct sunlight, moisture immersion and heavy pressure stacking.
