Product Description:
Sanyo Denki is among the global leading producers of industrial electronics. Belongs to the Super DC Servo Motor series, the brand manufacturers R406-011EL8 variant that provides strong drive power. Because of its 75 V rated armature voltage and 3,000 rpm nominal speed, it features quick position control. The component is further equipped with φ41 mm standard flange technology and operates as a plug-and-play solution. It also remains stationary during steady loads with its maximum torque value reaching 0.42 Nm.
For applications demanding both speed and strength, this DC motor accelerates up to 5,000 rpm and can instantly produce 1.8 Nm of torque to tackle sudden load spikes without hesitation. Its 11.7 Ω armature winding resistance, coupled with a thermal resistance of 2.8 K/W and a 20-minute thermal time constant, mainly strikes an ideal balance between efficiency and heat dissipation. With a built‑in 90 VDC holding brake locks in this module and a 2 A rated armature current, it delivers consistent torque control during extended operation. On the control side, the R406-011EL8 boasts a 4.1 mH armature inductance that smooths out current ripple for quieter, more uniform torque output.
With an electrical time constant of 0.45 ms and a mechanical time constant of 7.4 ms, this commercial motor responds swiftly to command inputs, enabling tight control loops and fluid acceleration or deceleration. Feedback accuracy is assured by its 1,000 P/R encoder and a tachogenerator load requirement of at least 10 kΩ. The ability to withstand instantaneous armature currents up to 10 A guards against overloads during peak demands.
