Product Description:
The P50B07040DBS00 is a brushless servo motor manufactured by Sanyo Denki within the P5 Super BL Servo Motors series. It uses permanent-magnet technology and a standard motor design to provide closed-loop rotary motion. The motor supports positioning, feed, and speed-control axes in industrial automation where compact 400 W drives are required and an IP-rated enclosure simplifies machine integration.
The motor develops a continuous mechanical output of 400 W while running at its rated speed of 3000 rpm. At this operating point, it produces 1.274 N·m of torque and draws 3.0 A RMS from the drive amplifier, providing useful values for sizing cabling, fusing, and thermal management. An enclosure rating of IP55 protects the motor against dust and low-pressure water jets. The 76 mm square flange accommodates common gearheads, while a phase resistance of 1.65 Ω and an electrical time constant of 4.0 ms govern current rise during rapid response. A torque constant of 0.481 N·m/A RMS relates commanded current to shaft torque. The rotor inertia of 0.74 × 10⁻⁴ kg·m² supports quick acceleration without placing an excessive load on the control loop.
Peak operating limits include a maximum speed of 4500 rpm and a maximum stall torque of 3.92 N·m, providing headroom for dynamic moves beyond the rated operating point. The motor includes a holding brake that is energized by a 90 V supply, consumes 0.08 A, and clamps the shaft with 0.98 N·m of torque to secure vertical loads when motor power is removed. Position feedback is supplied by a wire-saving incremental encoder that delivers a resolution of 2000 P/R, reducing the required connector count while maintaining fine positional granularity. The sealed housing protects internal components in compact machinery, while the integrated brake eliminates the need for a separate shaft-holding device.
