New FANUC A06B-0371-B575 AC Servo Motor Alpha A1/3000 0.3kW 3000 RPM

For buyers sourcing a dependable replacement servo motor for CNC and industrial motion systems, the FANUC A06B-0371-B575 is a practical Alpha-series option built for stable speed control and accurate positioning. This AC servo motor is associated with the Alpha A1/3000 configuration and combines compact 0.3 kW output with 3000 RPM performance, 1 Nm torque, a tapered shaft, IP65 sealing, and absolute feedback.

Key Technical Data

One of the strongest advantages of this motor is its balanced specification set. A 0.3 kW output class and 1 Nm torque make it suitable for precision axis movement where smooth response matters more than oversized motor capacity. The 3000 RPM maximum speed supports fast, controlled motion in compatible servo systems, while the 3-phase 90 V at 200 Hz electrical profile aligns with the known Alpha A1/3000 configuration for this model.

Mechanically, the tapered shaft helps provide secure coupling in the right installation environment, which is especially important in machinery where alignment and repeatability directly affect performance. This model is also listed without a brake, making it a better fit for applications that do not require a built-in holding brake at the motor level or already use system-level braking arrangements.

Another practical benefit is the fitted feedback system. This motor is associated with absolute feedback, which is an important feature in many servo-driven applications because it supports controlled motion reference and positional accuracy during machine operation. Combined with IP65 standard sealing, the A06B-0371-B575 is well suited for industrial environments where dependable operation and component protection are both important considerations.

For maintenance teams, resellers, and equipment rebuilders, the A06B-0371-B575 offers a focused replacement solution: compact output, high-speed Alpha-series performance, tapered shaft construction, and feedback-ready operation in one established FANUC servo motor package. It is a sensible choice for repair inventory, equipment restoration, and planned replacement work where matching the original technical profile matters.

FAQ

Q1: What type of motor is the FANUC A06B-0371-B575?
A: The A06B-0371-B575 is an AC servo motor from the FANUC Alpha series and is associated with the Alpha A1/3000 motor configuration. It is designed for controlled motion tasks in industrial and CNC equipment where positioning accuracy, stable response, and repeatable performance are required. Unlike general-purpose motors, servo motors of this type are intended to work within a motion control system that depends on feedback and precise command response.

Q2: What are the main specifications of the A06B-0371-B575?
A: The verified core data for this model includes 0.3 kW rated output, 1 Nm torque, 2.5 A current, 3-phase 90 V operation at 200 Hz, and a maximum speed of 3000 RPM. It is also listed with a tapered shaft, no brake, IP65 standard seals, and absolute feedback. These are the main points buyers usually compare when confirming compatibility for replacement or stock planning.

Q3: Does this servo motor include a built-in brake?
A: No. The A06B-0371-B575 is listed as a no-brake motor. This matters during replacement because some machines require a motor with an integrated holding brake, while others do not. Before ordering, it is important to compare the original installation carefully so the replacement matches both the electrical setup and the functional braking requirements of the machine.

Q4: Why is absolute feedback important on a servo motor like this?
A: Absolute feedback helps the control system identify motor position more effectively, which is valuable in applications where accurate positioning and motion reference are essential. In practical use, this supports smoother machine operation, better repeatability, and more reliable axis control in compatible systems. When evaluating a replacement servo motor, feedback type should always be checked alongside speed, voltage, and shaft style.

Q5: Is the A06B-0371-B575 suitable as a replacement motor?
A: In many cases, yes, provided the original equipment was designed for the same motor specification or a fully compatible equivalent. Buyers should verify the part number, output rating, voltage, current, maximum speed, shaft type, brake requirement, sealing level, and feedback configuration before purchase. A correct replacement decision depends on both mechanical fit and servo system compatibility, not appearance alone.
