Country of Origin
This motor is designed and manufactured by Fanuc Corporation in Japan, ensuring the highest level of reliability and compatibility with Fanuc CNC controllers and Alpha series amplifiers.
Application Fields
The α A12/2000 motor is a standard choice for heavy-duty industrial applications, including:
- CNC Machining Centers: Driving the X, Y, or Z axes for precise metal cutting.
- Injection Molding: Controlling the clamping or injection units in high-pressure machinery.
- Industrial Robotics: Providing high-torque rotation for Fanuc robotic arm joints.
- Automotive Production: Used in high-speed welding lines and assembly stations.
- Lathes and Turning Centers: Managing the spindle feed or turret indexing.
Product Usage Instructions
- Mechanical Mounting: Secure the motor using the flange mounting holes. For taper shafts, ensure the coupling is correctly seated and torqued to prevent slippage under high-acceleration loads.
- Electrical Connection: Connect the heavy-duty power cable to the U, V, and W terminals. The encoder cable must be routed separately from power lines to avoid electromagnetic interference.
- Brake Operation: Ensure the 24V DC brake release signal is synchronized with the drive enable signal to prevent motor stalls or brake wear.
- Parameter Configuration: Input the specific motor ID (from the B65142E manual) into the Fanuc CNC parameter screen to initialize the correct current loop and speed constants.
- Cooling: While the motor is self-cooling, ensure the rear fan fins (if applicable) are free of oil sludge or metal chips.
Product Technical Description
The Fanuc Alpha series utilizes high-density permanent magnets on the rotor to achieve superior torque-to-inertia ratios. The A06B-0142-B175-R features a low-cogging design, which provides extremely smooth rotation even at very low speeds—a critical requirement for high-quality surface finishes in CNC machining. The integrated pulse coder provides real-time position and speed feedback to the Alpha i amplifier, enabling closed-loop control with sub-micron precision.
Q&A (Common Questions)
Q: Can I replace an A06B-0142-B175 with this “-R” version? A: Yes, but the “-R” suffix usually denotes a specific shaft or brake configuration. Always verify that your machine’s physical dimensions and electrical connectors match before swapping.
Q: What is the meaning of the “B65142E” on the nameplate? A: This refers to the Fanuc technical manual code. It contains the detailed wiring diagrams, torque-speed curves, and maintenance procedures for this specific motor series.
Q: My motor is running hot; is this normal? A: These motors are rated for Class F insulation (up to 155°C), but if the casing exceeds 80-90°C, check for mechanical binding or excessive duty cycles in the CNC program.
Q: Is the encoder on this motor absolute or incremental? A: Most Alpha series motors use absolute encoders that retain position data even when the power is turned off, provided the amplifier’s battery backup is functional.
