Product Description:

The R2GA04008DXEEYM is a medium-inertia servo motor manufactured by Sanyo Denki for the R SANMOTION Servo Motors series. Designed for compact automation axes, the motor converts DC-bus power into controlled rotary motion for positioning tooling, conveyors, or small actuators. Integrated feedback supports precise regulation of shaft position and speed during automated motion sequences.

During continuous operation, the windings accept a supply of 48 VDC and draw a rated current of 4.1 A RMS. This input allows the shaft to maintain a rated speed of 3000 min⁻¹ while producing a rated torque of 0.255 N·m. The resulting mechanical output is 80 W under rated operating conditions. The motor face uses a 40 mm flange that mates directly with miniature gearheads, while its phase resistance of 0.32 Ω affects copper losses at the operating current. A main supply current of 6.6 A must be available from the DC bus to start and regulate the drive electronics. The power rate is 10 W/s, indicating how quickly mechanical output can increase within the motor’s thermal capacity. Because the motor does not include a holding brake, an external mechanism is required to secure vertical loads after power is removed. Compliance with CE marking requirements and applicable UL standards supports use in European and North American machinery.

For transient motion, the rotor can accelerate to a maximum speed of 5000 min⁻¹. Under these conditions, the electromagnetic circuit withstands a peak stall torque of 0.86 N·m, while the drive must supply up to 14.1 A RMS. The torque constant of 0.0693 N·m/A RMS relates commanded current to developed torque. The corresponding voltage constant is 2.42 mV per min⁻¹, representing the back electromotive force that the amplifier must overcome as speed increases. Sanyo Denki lists the RS2K04 as the compatible amplifier for this motor. This pairing provides suitable current-loop performance and protective settings for the motor’s medium-inertia rotor.
