Product Description:

The P50B08075DXS3T is a brushless servo motor with an integrated precision gearbox produced by Sanyo Denki for the P5 Super BL Servo Motors series. It converts drive commands into controlled rotational power for conveyors, loaders, and indexing tables in automated equipment. Its compact 80 mm frame and built-in reduction simplify machine layouts that need high torque at low speed.

On the motor side, the device supplies a continuous mechanical output of 750 W while drawing a rated phase current of 6.0 Arms. The motor shaft reaches a nominal speed of 3000 rpm and can accelerate to 4500 rpm during peak duty. A maximum instantaneous torque of 72.8 N·m is available to overcome startup or shock loads, while continuous motor torque is 2.381 N·m. The stator windings have a phase resistance of 0.43 Ω, and the rotor inertia is 1.926 × 10⁻⁴ kg·m², supporting a swift response. The square flange is selectable at 80 mm or 86 mm to match standardized mounting patterns, and the brushless construction eliminates brush wear. The integrated reducer provides a reduction ratio of 1/11, coupling the motor to the lower-speed output stage without external couplings.

With the gearbox engaged, the output shaft turns at 273 rpm and delivers 18.3 N·m of rated torque. Positioning repeatability is supported by a backlash of 3 arcmin, and power transmission efficiency through the gear train averages 70%. A square gear face measuring 120 × 120 mm simplifies direct frame mounting. The enclosure has an IP55 rating, allowing installation where dust or low-pressure water jets are present. Speed and position feedback is supplied by a wiring-saving incremental encoder with a resolution of 2000 P/R, allowing the drive to maintain precise closed-loop control without external sensors. Because the motor does not have a holding brake, static torque or an external clamp must secure vertical loads when power is removed.
