61BM220BXAT0 by Sanyo Denki

The 61BM220BXAT0 from Sanyo Denki is a high-performance BL Super Servo Motors series servo motor engineered for precise motion control in industrial automation environments. This device features a Power Output of 3.1 kW and operates over a Voltage Range of 24V DC to 48V DC, ensuring compatibility with a variety of drive systems. Weighing just 3.5 kg, the motor benefits from Natural convection cooling, minimizing auxiliary cooling requirements and simplifying mechanical integration. Equipped with an Incremental encoder with Hall sensors for closed-loop feedback, the 61BM220BXAT0 delivers repeatable positioning accuracy under dynamic load conditions. With a Lead Wire Length of 1000 mm and standardized mounting dimensions, this servo motor supports streamlined installation into existing machine frameworks and robotic assemblies.

The motor’s dynamic characteristics are defined by a Rated Speed of 2000 RPM and a Rated Voltage of 200 VAC, delivering smooth acceleration profiles and stable cruise performance. It draws a Rated Current of 14 Amps under nominal load and sustains a Continuous Current of 40A for extended operation, while peak demand can surge to 73A Peak Current for transient torque requirements. Torque generation is inherently linked to the encoder feedback and current control loop, enabling precise velocity regulation even under variable load conditions. The built-in sensor package interfaces directly with standard servo drives, minimizing control latency and ensuring rapid response to command inputs. The Protection Class IP20 rating provides basic enclosure safeguarding against solid foreign objects, while the sensor and winding assemblies remain accessible for routine maintenance.

Designed for reliability in factory environments, the 61BM220BXAT0 operates across an Ambient Temperature Range of 0 to 40°C without derating, ensuring consistent performance in sealed or ventilated enclosures. Its compact form factor and modest weight allow integration into robotic joints, pick-and-place systems, conveyor drives, and CNC indexers. The combination of encoder feedback, robust current handling, and efficient cooling simplifies integration into custom drive algorithms and motion controllers. As part of Sanyo Denki’s BL Super Servo Motors series, this unit adheres to rigorous quality standards and industrial certifications, making it well suited for continuous-duty manufacturing lines and automated assembly cells.
