Product Description:
The R2AAB8100FCH00 is a medium-inertia AC servo motor produced by Sanyo Denki within the R SANMOTION Servo Motors series. The unit couples directly to precision machinery and converts electrical energy into controlled rotary motion, allowing positioning tables, pick-and-place heads, and packaging axes to follow tightly regulated speed and torque commands issued by a matched amplifier. An integrated absolute encoder supports closed-loop feedback, allowing the controller to monitor the shaft position at single-turn resolution after a power cycle. This capability supports repeatable positioning in industrial automation applications.
Rated mechanical output reaches 1 kW, enabling the motor to drive moderate-inertia load systems without oversizing. Continuous torque is specified at 3.18 N·m, providing steady twisting force while the motor remains within its thermal limit. The electrical connection is designed for a 200 V class supply, so standard industrial inverters can energize the three phases through windings with a resistance of 0.44 Ω. Positional feedback is delivered by a high-density encoder that provides 131072 divisions per revolution, allowing the system to detect incremental motion as small as 0.0027°. The mounting interface uses an 86 mm square flange that mates with commonly available gearheads and brackets.
Dynamic moves are supported by a peak torque reserve of 14.3 N·m, giving the drive additional capacity for acceleration bursts or rapid indexing. With a maximum speed of 6000 rpm, the motor can produce short-term power above its continuous operating curve while remaining within its voltage constant of 20.3 mV per rpm. The motor and encoder have a combined mass of 3.6 kg, which helps limit reflected inertia when the assembly is directly coupled to lightweight stages. The rotor inertia is 2.38 × 10⁻⁴ kg·m², supporting predictable response in medium-range servo loops. The integral holding brake operates from 24 VDC and supplies 3.92 N·m of static friction torque to secure vertical loads when motor power is removed. During active control, the motor has a torque constant of 0.582 N·m/A rms.
