68ZBM140HBJ70 by Sanyo Denki

The 68ZBM140HBJ70 from Sanyo Denki is a high-performance servo motor within the ABS Super Servo Motors series, engineered for precision industrial automation. This device operates on 400V AC power and delivers a Limiting Speed (grease) of 3,000 rpm, with a maximum of 6,500 rpm to accommodate versatile motion profiles. Its robust construction features a Bore Diameter: 140 mm and an Outer Diameter: 210 mm, ensuring compatibility with standard mounting interfaces. Designed for radial force applications, the motor features a Load Direction: Radial specification that supports demanding industrial environments. Crafted from Material: Chrome Steel and fitted with a durable Cage Material: Steel, this servo motor balances strength and reliability for long-term operation.

Technical excellence is evident in the motor’s precision components, including a 23-bit battery-less absolute encoder providing high-resolution positional feedback. The Static Load Rating (cor): 225,000 N and Dynamic Load Rating (cr): 241,000 N underline its capacity to sustain substantial loads without performance degradation. With a Precision Rating: Standard and an Open Seal Type design, the motor offers consistent accuracy and ease of maintenance. The compact Width: 33 mm profile contributes to a small installation footprint, while the chrome steel rotor and stator configuration optimize torque density. Limiting speeds are further enhanced by an optional Limiting Speed (oil): 4,000 rpm lubrication scheme for extended high-speed duty cycles.

Operational reliability is fortified through integrated safety and durability features. The servo motor includes a 24V DC holding brake to maintain shaft position during power interruptions, while the resilient chrome steel construction withstands up to 4.9 m/s² vibration loads for stable performance. It functions within an ambient temperature range of 0°C to 40°C, ensuring dependable operation across diverse environments. Lubrication options—grease or oil—enable maintenance flexibility, and the open seal design simplifies inspection and servicing. An IP65 rating provides protection against dust ingress and low-pressure water jets, securing the motor’s electronics in challenging conditions.

Integration into automation systems is seamless, with the 130 mm flange opening accommodating standard couplings and the motor’s mounting geometry aligning with industry conventions. The 68ZBM140HBJ70 pairs effectively with SANMOTION R series amplifiers to achieve synchronized motion control, simplifying system commissioning and tuning. Its balanced combination of torque capability, precision feedback, and durable construction makes this servo motor ideal for robotics, packaging machinery, conveyor systems, and other industrial applications requiring high torque density and reliable performance.
