Product Description:

The P60B18550RBAT4E belongs to Sanyo Denki’s P6 Super BL Servo Motors series and is a brushless AC motor intended for precision positioning in industrial automation. A high-resolution absolute encoder supplies position feedback for tight control of speed, torque, and rotary movement. The integral holding brake helps prevent unwanted shaft movement when the axis is stopped. These features support controlled motion in robots, machining centers, conveying equipment, and other automated machinery with demanding positioning cycles.

Under continuous duty, the motor delivers 5.5 kW of mechanical power at 1500 rpm. At this operating point, it produces 35.0 N·m of shaft torque and draws 32 A rms from the drive. The torque constant is 1.18 N·m/A rms, allowing commanded current to scale proportionally with torque across the servo operating range. A voltage constant of 41.2 mV per rpm indicates the generated back electromotive force, while the phase resistance of 0.040 Ω helps determine copper losses during steady operation. Position feedback is supplied by an absolute encoder with 2,048 divisions, providing absolute position information that corresponds to the ABS-E designation. The motor uses a 180 mm square flange for mounting to compatible metric machinery and gearboxes. It carries CE marking, and its brushless design eliminates current-carrying commutator contacts that would otherwise be subject to mechanical wear.

For short operating intervals, the shaft can deliver 88.3 N·m while the windings accept up to 83 A rms, providing additional torque for rapid acceleration. When the rotor is locked, the motor withstands 37.3 N·m at a stall current of 33 A rms, and indexing moves can reach 2500 rpm. The brake coil operates at 90 V, allowing compatible control circuitry to release the holding brake when motion is commanded.
