Product Description:
The R2AA18450HXR94M is a servo motor in the R SANMOTION Servo Motors series produced by Sanyo Denki. Its medium-inertia design supports precise rotary motion in automated machining centers, packaging lines, assembly robots, and other equipment that requires controlled movement under changing loads. When paired with a compatible drive amplifier, the motor converts electrical power into regulated torque and speed for industrial positioning axes.
The flange measures 180 mm, allowing the shaft center to align with compatible size-180 gearheads and couplings. A compatible drive rated for a peak current of 150 A provides the current needed for short acceleration periods without limiting the commanded torque. The motor has an apparent power requirement of 7.4 kVA, which must be considered when sizing the electrical supply. During rapid indexing, the shaft can deliver a peak torque of 75.0 N·m for brief acceleration and deceleration demands. The winding has a phase resistance of 0.065 Ω, which affects copper losses and voltage drop as motor current rises. Its rated power rate is 92 kW/s, indicating how quickly mechanical output can increase during high-throughput motion cycles.
The motor operates from a 200 V three-phase supply. Under rated operating conditions, the winding draws 23.7 A rms and produces a shaft output of 4.5 kW. The rotor reaches a rated speed of 2000 rpm while producing 21.5 N·m of continuous torque within its thermal operating limits. A voltage constant of 35.6 mV per rpm supports the back-electromotive-force calculations performed by the drive controller. The motor does not include a holding brake, so powered torque or an external mechanical clamp must secure vertical loads when electrical power is removed. Compliance with CE and UL requirements supports installation in machinery intended for markets that recognize those standards. The balance between rotor inertia, continuous torque, and peak output supports stable acceleration in pick-and-place systems, servo presses, and other repetitive-motion applications.
