Product Description:

The L402-021EL0 is a compact servo motor developed by Sanyo Denki which features a durable, black-anodized front plate and operates at 23W power consumption and it offers reliable performance and efficiency for precision tasks in industrial automation environments.

The L402-021EL0 servo motor needs 1.9 ampere amount of typical electric flow during standard use which means it requires a modest current that suggests it is efficient and suitable for applications with limited power supply capability. Its total electrical demand sums up to 24 volts amperes and it is designed to be affixed using a square or rectangular faceplate, secured with four bolts which allows for stable and secure installation. It has an internal device for tracking position or speed which allows it to send feedback and enables precise control which is a cornerstone for closed loop systems. Its rotational velocity is relatively high and equivalent to 3000 rpm which is suitable for applications needing fast motion or rapid actuation and its mechanical output amounts to 23 watts which reflects its energy conversion into motion. Its output shaft has a flat section which is a mechanical design choice that prevents slipping when connected to gears, pulleys or couplings which ensures torque transfer remains consistent, especially under load.

This Super DC series servo motor total apparent electrical energy requirement is 24 volts amperes and it best operates at 24 volts DC which is standard in automation and robotics that makes it easy to integrate with off-the-shelf power systems and PLCs. The module draws amperage under normal load up to 1.9 amperes which reinforces that idea that it does not place excessive strain on the electrical infrastructure and it is capable of making 3000 revolutions in a minute which confirms its suitability for relatively high speed applications.

Frequently Asked Questions about L402-021EL0:

Q: Why is a black-anodized front plate used in the L402-021EL0 motor?

A: The black anodized finish offers corrosion resistance and reduces surface wear in tough environments. It helps maintain structural integrity over long-term industrial use.

Q: How does the built-in encoder in L402-021EL0 enhance motion control?

A: The encoder provides real-time position feedback for closed-loop accuracy. This ensures high-precision adjustments in dynamic automation systems.

Q: Can the L402-021EL0 operate on battery-powered systems?

A: Yes, its 24V DC input and 1.9A current draw suit low-power or battery-based systems. It’s ideal for mobile automation or compact robotics.

Q: What benefits does the 4-bolt flange mounting offer in L402-021EL0?

A: It provides mechanical stability and vibration resistance. This ensures consistent performance in high-speed or high-cycle industrial operations.

Q: Why is 3000 RPM an ideal speed for L402-021EL0 servo motor applications?

A: It allows fast response times in applications requiring quick acceleration. This speed is commonly used in pick-and-place or conveyor systems.
