R12A831802

The Sanyo Denki R12A831802 servo motor from the ABS Super Servo Motors series is engineered for demanding industrial automation applications. This face-mounted module provides a rated torque of 754 in-lbs (85.2 Nm) and a rated output speed of 1800 rpm, delivering a horsepower output of 2.0 hp (1.49 kW) for robust motion control. Its cast iron housing ensures structural rigidity and resists deformation under high torque loads, while the mounting type: Face Mounted configuration simplifies direct integration into machine frames. The motor’s compact design weighs just 38 lbs (17.2 kg), offering an excellent power-to-weight ratio that reduces mechanical strain. Early mention of part_number R12A831802, manufacturer Sanyo Denki, and series ABS Super Servo Motors underscores its pedigree in precision automation. Its versatile specifications make it suitable for packaging, robotics, and CNC machinery where compactness and power density are critical.

Performance characteristics emphasize responsiveness and stability under variable loads. The integrated IP65 enclosure rating provides dust-tight protection and resists water jets, ensuring reliable operation in harsh environments. This unit endures mechanical shocks up to 490 m/s2, safeguarding internal components during sudden impacts. The ratio of 1:2 gear setting balances torque and speed for versatile machinery setups, while the output shaft diameter of 1.25 in (31.75 mm) and input shaft diameter of 0.875 in (22.23 mm) support standard couplings and encoder mounts without adapters. Efficiency exceeds 85%, minimizing energy consumption and heat buildup during continuous operation. These technical features combine to deliver precise position control and rapid response in high-duty-cycle scenarios.

Designed for long-term reliability and seamless integration, the R12A831802 operates across an operating temperature range of -20°C to +80°C, covering cold-storage and heated plant environments. Its Class B insulation extends winding life by tolerating elevated temperatures, reducing maintenance intervals. The motor accommodates up to 10x rotor inertia allowable load inertia, maintaining tight speed regulation even under sudden load changes. At 38 lbs (17.2 kg), the unit adds ballast for vibration damping without imposing excessive mass on drive systems. Ideal for industrial automation, pick-and-place robots, and assembly lines, this servo solution balances performance, durability, and ease of installation to meet rigorous production demands.
