Product Description:
The L404-012E18 DC servo motor is a component of the SANMOTION Super L series, which is developed by Sanyo Denki. The motor is made for small motion control applications that need a steady output and to save space. It can perform automation duties that are essential in motion-based setups and precise systems.
The L404-012E18 DC servo motor is defined as producing 0.04 kW of power when the stator voltage is set to 72 V. At its default speed, the motor operates at 3000 revolutions per minute; however, it has the capacity to accelerate to 5000 revolutions per minute. The torque output has a constant stall torque of 0.14 N·m that lets it handle loads for a long time. The high stall torque is 0.76 N·m, which controls overloading in the short term. The rotor's inertia is 0.00084 kg·m², which helps keep the action stable when it speeds up or slows down. The motor is connected with a lead wire, which makes it easier to connect to motion controls. There is a protection rating of IP43 on the L404-012E18 that keeps dust out but doesn't completely stop water sprays. The motor weighs only 0.4 kg, which means it can be mounted in small frames. In normal conditions, the motor works well in ranges between 0°C and 40°C.
The lead wire length on the L404-012E18 servo motor is 1000 mm, and it has an IP43 grade for protection. These features work well with panel-mounted systems that need simple wiring layouts and few changes to the insulation. The motor can be mounted permanently and can connect to electrical systems consistently in small units. The motor has a flange size of 41 mm and was built to very exact measurements. The design allows for consistent operation when reducing weight and aligning parts is needed.
Frequently Asked Questions about L404-012E18:
Q: Why does L404-012E18 support 72 V input?
A: The 72 V armature voltage is selected to match drive controller compatibility and maintain thermal stability under prolonged operation.
Q: How does L404-012E18 manage dynamic load changes?
A: The peak stall torque of 0.76 N·m enables the motor to withstand short bursts of increased mechanical resistance during motion.
Q: Why is rotor inertia low in L404-012E18 motor?
A: Rotor inertia of 0.00084 kg·m² enhances fast response and minimizes overshoot during acceleration and deceleration cycles.
Q: Do L404-012E18 motors include lead wire connection?
A: Yes, the motor includes a lead wire type connection that simplifies electrical setup and enhances wiring flexibility in tight enclosures.
Q: How does L404-012E18 function in 0–40°C range?
A: The specified ambient range ensures thermal reliability, allowing consistent performance without derating or overheating during normal duty cycles.
