Product Description:
The R2AA04010FCP00 is a medium-inertia servo motor produced by Sanyo Denki for the R SANMOTION Servo Motors series and intended for position and speed control in compact industrial axes. Its 40 mm mounting flange accommodates small gearheads or direct-drive couplings, while the integrated 24 VDC holding brake secures the load when power is removed. A battery-backed absolute encoder supplies position data to a compatible SANMOTION R amplifier, allowing the drive to retain the known shaft position across power cycles. This arrangement supports controlled motion in pick-and-place heads, electronic assembly machines, semiconductor equipment, and other automated systems with limited installation space.
This model operates from a three-phase 200 V supply and delivers a continuous mechanical output of 100 W at its rated shaft speed of 3000 rpm. Under locked-rotor conditions, it can develop a peak stall torque of 1.18 N·m, providing the short-duration force needed for rapid indexing of light fixtures or positioning stages. Its voltage constant is 14.8 mV/rpm, indicating the back electromotive force that the drive must counter as shaft speed increases. The rotor inertia is 0.066 × 10⁻⁴ kg·m², balancing responsive acceleration with resistance to sudden load disturbances. The motor uses three-phase power, allowing the amplifier to regulate current through the stator windings and produce smooth rotary motion throughout the operating range.
The motor can operate at speeds up to 6000 rpm, providing additional velocity above its rated operating point for intermittent high-speed motion. Current-controlled torque regulation uses an electromagnetic constant of 0.424 N·m/Arms and a stator resistance of 9.3 Ω, allowing the drive to regulate torque and estimate winding losses. The holding brake coil draws 0.27 A, and its friction element provides 0.32 N·m of holding torque to prevent movement on vertical axes when motor power is unavailable. The battery-assisted absolute encoder provides 131072 counts per revolution and tracks as many as 65,536 mechanical revolutions. This stored multi-turn position information removes the need for a routine homing cycle after power is restored, provided the encoder backup supply remains functional.
