Product Description:

The Sanyo Denki 61BM120BBAF0 is an ABS Super Servo Motor designed for precise industrial automation. It features a 120 mm square flange and a rated torque of 3.8 N·m. This motor operates at 230 V with a rated current of about 5 A and reaches a speed of 3000 rpm.

The 61BM120BBAF0 motor offers a rated output power of approximately 1.2 kW. Strong dynamic performance allows for a peak stall torque of around 10 N·m for short periods of time. The shaft diameter is 19 mm with a length of around 40 mm making it appropriate for compact mounting. The motor cooling is based on natural convection which enables efficient self-cooling. The electrical time constant ranges between 10 and 20 milliseconds. The mechanical time constant is approximately 1.5 milliseconds. Protection is enhanced by an optional IP67 rating which requires waterproof connectors for full sealing. This makes the motor ideal for harsh or wet environments. The holding brake is available in 24 V or 90 V DC, with mounting holes ranging from M6 to M8 depending on the brake arrangement. The torque constant is approximately 0.75 N·m per ampere. The motor provides exact position feedback using an ABS absolute encoder (ABS-E type). It works with a variety of encoder types including incremental and ABS-RII absolute sensors. Phase resistance is approximately 0.2 ohms by optimizing current flow for consistent operation.

The Sanyo Denki’s 61BM120BBAF0 ABS Super Servo Motor combines reliability, high precision and flexibility. Its compact 120 frame size suits systems requiring space saving without sacrificing power. Operating temperatures range from -10°C to +40°C making it adaptable to many industrial settings. The weight falls between 4.5 and 5.5 kg that balances robustness. The motor’s IP67 option and encoder compatibility ensure it performs well in demanding industrial applications.
