L404-011EL8
by Sanyo Denki
The Sanyo Denki L404-011EL8 is a high-performance DC servo motor from the Super DC Servo Motors series, designed for precision motion control in industrial automation. With a rated output of 40 W and a rated torque of 0.13 N·m, this compact unit excels in applications requiring consistent mid-range power. Its primary function is to deliver smooth, responsive motion for automated equipment in constrained spaces, making it ideal for pick-and-place and indexing systems.
Detailed technical specifications of the L404-011EL8 highlight its advanced motor design. The servo operates at a rated voltage of 24 V and draws a rated current of 2.7 A to sustain steady performance. It achieves a rated revolving speed of 3000 min⁻¹ for rapid positioning, while a torque constant of 0.048 N·m/A ensures efficient torque generation per ampere. The motor’s armature resistance of 2.8 Ω and electrical time constant of 0.32 ms contribute to its quick electrical response, whereas the mechanical time constant of 6 ms underpins fast acceleration and deceleration cycles. A max stall torque of 0.40 N·m and max stall current of 7.2 A provide robust overload handling. Feedback is managed by an incremental encoder with an induced voltage constant of 4.9 mV/min⁻¹.
Built for reliability, the L404-011EL8 weighs 0.4 kg including its encoder, facilitating lightweight machine designs. It features an IP43 protection rating for resistance to dust and light splashes and operates in ambient humidity levels up to 90% RH (non-condensing). A 1000 mm lead wire connection enables flexible installation, while the D-shaped output shaft ensures secure coupling to driven components. The servo’s low-voltage design minimizes energy consumption, enhancing system efficiency. In industrial applications, this motor delivers precise, repeatable motion control, boosting productivity and reducing maintenance requirements.
