R404-011E27

Product Description:

The R404-011E27 by Sanyo Denki steps into the Super DC Servo Motors lineup with a build tuned for steady performance in compact machinery and tight workspaces. Here, the motor’s rated output sits at 40 watts, and a neat 0.13 N·m of torque is on offer—not a heavyweight for large conveyor belts but reliable where small movement matters. This motor spins up to a maximum speed of 5000 min⁻¹, which means plenty of motion control options are available for things like automated testers or assembly pick-and-place rigs. A torque constant of 0.047 N·m/A makes the relationship between current and torque pretty direct, which helps engineers when tuning motion controls and planning for system loads.

Where space weighs into installation decisions, a mass of 0.25 kg keeps things portable and reduces any heavy strain on fragile mounts. The armature winding resistance comes in at 2.8 Ω and inductance at 0.9 mH, showing the design leans toward accurate, quick responses rather than brute power. For voltage and current, the rated specs show 20 V on the armature and 1.8 A, both numbers that fit well into many motion modules found in modular industrial control units. Stall conditions are handled with a continuous stall torque of 0.08 N·m, and the specs point to solid running even where demand goes up and down unexpectedly. Protection for moving parts comes through a low friction torque, measured at 0.015 N·m—helpful for applications swinging back and forth a lot in short bursts.

On the mechanical side, this servo comes balanced with a rotor inertia of 0.0047×10⁻³ kg·m², which cuts down on shake during starts and stops. The finish is tidy and designed with tight tolerances. Integration with automation setups is straightforward, since these specs sit right in line for industrial robots, printing lines, and other spots needing constant, quick shifts.
