Product Description:
The R2GA04005FXH00M servo motor is manufactured by Sanyo Denki for the R SANMOTION Servo Drives series. It is intended for compact industrial axes where precise velocity and position control are required. When paired with a compatible drive, the motor translates low-voltage DC power into accurately metered shaft rotation, allowing controllers to move tooling, conveyors, or small actuators inside automated equipment.
The motor is powered from a bus of 48 VDC, so it can be installed in light-duty machines that rely on a safe extra-low-voltage supply. Its mechanical output is rated at 50 W, a level suited to indexing fixtures and miniature gantries. Nominal operating speed reaches 3000 rpm; this base velocity supports gear-ratio selection when fixed mechanical cycles are required. The built-in encoder provides a resolution of 131,072 positions (17-bit), giving controllers fine incremental feedback for smooth interpolation. A 40 mm square frame matches standard miniature gearbox and bracket patterns, simplifying mounting. Rated torque is 0.159 N·m, while a phase resistance of 0.33 Ω affects copper loss and current demand. The PA035S sensing head provides single-turn absolute tracks, and the medium-inertia rotor balances acceleration capability with load stability.
The motor delivers a peak stall torque of 0.54 N·m for short-term overloads, whereas its continuous stall torque is 0.167 N·m for steady holding situations. During transient moves, the windings can draw up to 3.8 A RMS, a value that supports proper amplifier sizing and cable-gauge selection. The maximum no-load speed reaches 6000 rpm, enabling rapid positioning before the motor returns to its rated-speed duty point. Because no oil seal is fitted, the shaft should be used in clean environments or paired with external sealing hardware.
