R511-012W18
by Sanyo Denki
The R511-012W18 by Sanyo Denki is a high-performance member of the Super DC Servo Motors series designed for demanding industrial automation environments. Delivering a rated power of 90 W, this compact drive operates at a rated armature voltage of 75 V and achieves a rated rotating speed of 3000 rpm to meet precise motion control requirements. Its continuous stall torque of 0.42 Nm and instantaneous maximum torque of 1.8 Nm ensure smooth operation under variable load conditions, while a maximum rotating speed of 5000 rpm offers dynamic responsiveness for high-throughput applications. Built with an armature inductance of 4.8 mH and an armature winding resistance of 11.7 Ω, the R511-012W18 balances electrical efficiency with reliable torque delivery. With a weight-optimized design and CE certification, this servo motor integrates seamlessly into existing machine architectures with minimal footprint impact.
Performance is further optimized through a rated armature current of 2 A and a stall armature current of 1.3 A, delivering controlled acceleration and deceleration profiles. The motor’s electrical time constant of 0.45 ms and mechanical time constant of 7.4 ms facilitate rapid response to control signals, while the voltage constant of 19.1 V/min^-1 ensures predictable speed regulation across the operating range. Thermal management is addressed via a thermal resistance of 2.8 K/W and a thermal time constant of 20 min, allowing sustained operation under continuous load without performance degradation. High-voltage isolation and an integrated CAN interface (designation 02) provide robust connectivity and noise immunity for industrial fieldbus networks. This combination of electrical and thermal characteristics underpins the motor’s capability to deliver stable torque output in automated manufacturing, packaging, and assembly systems.
Reliability is assured through full electrical isolation and compliance with CE safety standards, safeguarding both equipment and personnel. The R511-012W18 supports simple screw mounting and can be paired with the TB712 terminal block for secure installation in control panels or machinery frames. Rated to operate in relative humidity up to 90% and at altitudes up to 2000 m, this servo motor maintains consistent performance in varied environmental conditions. Its compatibility with standard industrial controllers and fieldbus protocols makes it an ideal choice for robotics, conveyor systems, and precision positioning applications. By combining responsive dynamics with robust construction, the Sanyo Denki R511-012W18 enables seamless integration into complex automation solutions where reliability and accuracy are paramount.
