Description

Product Overview

The MOOG G403-552A is identified in available industrial product references as a brushless AC servo motor from the Moog G400 family. It is intended for precision motion-control applications where controlled speed, torque, and positioning are required. Published supplier data associates this model with a 0.95 kW rating, approximately 325 V operating voltage, 3.2 A rated current, and a maximum speed of up to 8,000 rpm.

The brushless motor construction eliminates conventional mechanical commutator wear, making it suitable for repetitive industrial motion. Depending on the exact motor configuration and nameplate, feedback and braking arrangements may vary, so the complete model designation should always be checked before procurement. This is particularly important for replacement work, where mounting dimensions, feedback device, brake voltage, winding data, and compatible drive parameters must match the installed machine.

Technical Specifications — G403-552A

Available sources consistently identify G403-552A as a Moog servo motor, although third-party specifications differ on mechanical and environmental details. Those values should therefore be treated as configuration-dependent rather than universal.

Key Features and Benefits — G403-552A

• Brushless AC servo construction for controlled industrial motion.
• High-speed operation, with published data indicating up to 8,000 rpm.
• Approximately 0.95 kW rated output for medium-duty motion applications.
• Suitable for closed-loop positioning, speed regulation, and torque-control systems.
• Compatible drive selection can provide precise acceleration and deceleration control.
• Appropriate for machine tools, automated machinery, positioning equipment, and other servo-driven applications.
• Compact permanent-magnet motor architecture reduces routine mechanical wear.

The motor should be evaluated as part of a complete servo system rather than as an isolated electrical component. Drive voltage, motor constants, feedback type, brake wiring, and controller configuration all affect compatibility.

MOOG G403-553A: A related G403-series designation associated with a different power and torque configuration. It should not be considered a drop-in replacement without engineering verification.

MOOG SM23165D: A Moog servo-system component appearing in the same industrial motion-control product environment. Compatibility depends on the specific motor-drive combination.

MOOG D136 series: Moog digital servo-drive products used in industrial motion-control applications. The exact drive model must be matched to the motor’s electrical and feedback parameters.

Installation and Maintenance — G403-552A

Before installation, verify the complete motor nameplate, winding configuration, rated voltage, current, maximum speed, feedback device, brake specification, shaft arrangement, and mounting dimensions. Confirm that the servo drive has the correct motor parameter set.

Use appropriate shielded motor and feedback cabling, maintain proper grounding, and follow the drive manufacturer’s commissioning procedure. Do not energize the motor until phase connections and feedback wiring have been verified.

During maintenance, inspect bearings, shaft seals, connectors, cable insulation, mounting hardware, and brake operation where fitted. Abnormal vibration, overheating, noise, or encoder faults should be investigated before continued operation.

Product Warranty — G403-552A

Warranty coverage depends on the supplier, product condition, and purchase agreement. For critical motion-control spares, request serial-number traceability, nameplate photographs, test documentation, and confirmation of motor condition before purchase.

The MOOG G403-552A is best managed as a configuration-specific servo motor spare. Personally, I would not approve a replacement based on the model number alone; the feedback and brake configuration are just as important as the motor’s rated power.
