Product Description:
The R2AA18750HXS9DM is a medium-inertia AC servo motor produced by Sanyo Denki for the R SANMOTION Servo Motors series. Intended for precise positioning and speed regulation in automated machinery, it delivers closed-loop performance when paired with a compatible SANMOTION drive controller. Its rotor characteristics support controlled acceleration and deceleration in indexing tables, handling systems, and other motion applications. The motor is supplied without a holding brake, so installations that require power-off holding torque must use an external mechanical restraint.
At the electrical interface, the motor operates on a 200 V class supply and draws a continuous phase current of 51.2 A rms at rated load. This input produces a mechanical output of 7.5 kW while the motor runs at a rated speed of 1500 rpm, generating 48.0 N·m of rated torque. Continuous stall torque reaches 54.9 N·m, allowing the axis to produce static torque without overheating when operated within the applicable thermal limits. The rated power rate is 235 kW/s, indicating the motor’s acceleration capability under dynamic loads. A phase voltage constant of 36.6 mV/rpm represents the back electromotive force generated in relation to rotor speed. The motor carries CE and UL certifications for use in systems subject to common safety and electromagnetic compatibility requirements.
The motor has a 180 mm square flange that mates with heavy-duty gearheads or direct-drive machine frames. During rapid transients, the rotor can produce a peak stall torque of 140.0 N·m, providing torque above the continuous operating range for quick indexing movements. Control resolution is supplied by a wire-saving incremental encoder that transmits feedback signals and receives power through a reduced pin count. The winding has an impedance of 0.03 Ω, which helps the controller regulate current during changes in speed and load. A torque constant of 1.04 N·m/A rms allows the controller to calculate expected torque from the commanded current. These electrical and feedback characteristics support responsive motion while the drive monitors current, speed, and rotor position throughout each operating cycle.
