Product Description:

Sanyo Denki L511-012EL8 Servo Motor is designed for precision and agility and this 110 watt module reaches speeds up to 3000 RPM which makes it ideal for compact automation systems such as robotic mechanisms, motion platforms and other applications requiring accurate and responsive movement.

The L511-012EL8 is featured with a pre-attached electrical lead ending in a molded plastic plug such as a four pin or multi contact connector which makes it easier to link the motor to control systems without manually wiring individual terminals. It equips a protruding cylindrical drive shaft, designed with a machined groove or notch and it has a secondary bundle of thin, black and white cables emerges from the motor housing which may interface with a built-in rotary encoder or similar sensor that continuously reports motor performance to a controller. It is made to dissipate heat naturally, without the assistance of fans or liquid cooling systems as its metal casing likely acts as a heat sink which releases thermal buildup through surface radiation and convection. It functions at a nominal draw of 2 amperes which indicates its typical electrical load during continuous operation and it includes a faceplate with four precisely positioned bolt holes for secure fastening which is a common mounting type in automation setups.

This L511-012EL8 Servo Motor is rated to run on 75 volts of direct current which suggests it is intended for use in medium power industrial systems, robotic arms or CNC machinery where stable and regulated DC supplies are available. The module main casing is a completely enclosed housing that is made from aluminum or steel which provides protection from dust, debris, and minor moisture and ensures longevity and reliability, particularly in factory or lab environments.

Frequently Asked Questions about L511-012EL8:

Q: How does the key slot on the shaft of L511-012EL8 improve torque transfer?

A: The machined groove securely fits a key, ensuring zero slippage during torque transfer. This allows accurate mechanical alignment in high-load or precise motion applications.

Q: Why is natural convection cooling important in the L511-012EL8 servo motor?

A: Passive cooling reduces moving parts and increases reliability over time. It’s ideal for environments where noise or maintenance access is limited.

Q: What advantages does the flange mount design provide for the L511-012EL8?

A: The four-bolt flange ensures rigid and stable mounting. It simplifies alignment in automation setups and reduces vibration during operation.

Q: Can the built-in encoder wiring in L511-012EL8 be used for precise position control?

A: Yes, the encoder feedback allows closed-loop control for precise motor movement. This is especially beneficial in robotics and CNC systems.

Q: Why is a 75V DC supply chosen for this model instead of a lower voltage?

A: Higher voltage supports better torque-speed characteristics. It also reduces current draw, minimizing power losses in extended cable runs.
