69BM014CBRY1 by Sanyo Denki

The Sanyo Denki 69BM014CBRY1 servo motor is a high-precision drive solution in the ABS Super Servo Motors series, designed for demanding industrial automation tasks. It delivers 600 W of continuous power output and sustains a rated torque of 4.0 Nm at a rated speed of 1500 RPM, with an operating voltage of 200 V for consistent motion control. The unit features a robust bevel gear design integrated directly into the motor housing, ensuring compactness and durability. A high-accuracy absolute encoder provides position feedback for precise control, making this servo motor suitable for applications where stability and repeatability are critical. Its flange mount configuration supports straightforward installation in space-constrained systems.

The motor’s mechanical interfaces include a bore diameter of 7 mm and a hub diameter of 15 mm, with a hub length of 11 mm and a keyway width of 3 mm to accommodate standard coupling hardware. The output shaft is fitted with a bevel gear featuring a face width of 8 mm and an outside diameter of 24 mm, cut from SCM415 steel and hardened to 50–60 HRC for wear resistance. This gear uses a module of 1.5 and has 14 teeth with a pressure angle of 20°, enabling precise torque transmission. On the electrical side, the drive draws a rated current of 2.6 A and employs natural convection cooling to eliminate auxiliary cooling systems. The encoder delivers 14-bit resolution (16,384 positions per revolution) via an absolute interface, supporting SSI, BiSS, and parallel output protocols for flexible integration.

Operational performance is enhanced by the gear’s bevel geometry, which reduces backlash and evenly distributes load across the tooth flanks. The sealed housing provides mechanical durability and vibration resistance suitable for industrial environments. With a compact form factor and pre-attached multi-pin plastic connectors for power and signal cables, the unit minimizes installation time and wiring complexity. The absence of an integrated brake simplifies the rotor assembly and reduces maintenance requirements. Overall, the combination of robust gear mechanics and precision feedback ensures reliable dynamic response and long service life under continuous duty cycles.

System integration is streamlined through compatibility with a wide range of servo drives and controllers via the encoder’s versatile communication protocols. The flange mounting system and standardized shaft interfaces facilitate direct replacement or retrofit in robotic assemblies, CNC machinery, and packaging equipment. The 69BM014CBRY1 is especially well suited for industrial automation applications where compact design, high torque density, and precise motion control are essential. Its rugged construction and flexible control options make it an ideal choice for advanced manufacturing systems, pick-and-place units, and precision indexing tables.
