Product Description:

The P80B22350HXS28 is a brushless AC servo motor designed and manufactured by Sanyo Denki as part of the P8 Super BL Servo Motors series. The unit converts electrical energy into controlled rotary motion for positioning tasks in industrial automation. It connects directly to matched servo amplifiers through its incremental feedback interface.

At the continuous operating point, the motor delivers a rated mechanical output of 3.5 kW while drawing a phase current of 24.3 A RMS. This current produces a steady shaft torque of 17.0 N·m at the rated speed of 2,000 rpm, providing a balance between torque density and thermal loading. The frame carries an IP67 protection rating, so the stator windings and bearings remain sealed against dust and temporary immersion. Position feedback is supplied by an incremental encoder with reduced wiring and a resolution of 2,000 P/R, allowing the drive to detect motion with sub-degree accuracy without additional signal cables. A 220 mm square flange provides a standardized mounting interface, and the low phase resistance of 0.036 Ω minimizes copper loss during sustained operation.

For rapid transients, the motor can deliver a peak torque of 50.0 N·m, and the rotor can accelerate to a maximum speed of 3,000 rpm when commanded by the drive. Dynamic response is supported by a mechanical time constant of 0.76 ms and a rotor inertia of 43.1 × 10⁻⁴ kg·m², enabling quick positioning cycles in gantry axes or indexing tables. The electromagnetic design provides a torque constant of 0.78 N·m/A RMS, simplifying current-loop tuning in the servo controller. The unit has a mass of 18.5 kg, allowing rigid installation without excessive structural reinforcement. Its electrical time constant is 31 ms. The motor has no holding brake, so external clamping is required to maintain position when the drive is de-energized.
