Product Description:
The R2GAD102RMXH00 miniature servo motor is produced by Sanyo Denki within the R SANMOTION Servo Motors series. This middle-inertia brushless unit delivers precise, low-power rotation for compact automated stages and laboratory devices. In an automation loop, the motor connects to a DC servo amplifier and converts voltage commands into controlled shaft motion. Position feedback allows the amplifier to regulate the motor through closed-loop control, supporting accurate movement during indexing and positioning tasks.
The motor supplies 2.4 W of mechanical power and 0.023 N·m of continuous torque at a shaft speed of 1000 rpm. Current draw during steady operation is 0.67 Arms, while the stall armature current is 0.64 Arms. The windings operate from a 48 VDC supply, and torque increases in proportion to current with a constant of 0.042 N·m/Arms. For brief acceleration periods, the drive can deliver a peak current of 1.7 Arms, allowing the motor to exceed its continuous load for rapid movement. The middle-inertia rotor supports stable servo response during changes in speed or load. A 14 mm square mounting flange positions the compact motor frame against the machine surface. The motor is supplied without optional protection upgrades.
The motor produces a peak stall torque of 0.06 N·m for rapid indexing before operation returns to the continuous limit. The stator has a resistance of 7.2 Ω, which the controller can use when estimating winding temperature during demanding cycles. Back electromotive force follows a voltage constant of 1.47 mV/min⁻¹. Rotor position is reported by an absolute encoder with a resolution of 131,072 divisions per revolution, providing fine feedback for the connected control system. The high encoder resolution allows the amplifier to detect small changes in shaft position and make precise corrective adjustments. No holding brake is installed, so applications that require the shaft to remain locked after power is removed must use an external clamp or another mechanical holding device.
