Product Description:
The P80B22450LCPUB is a brushless AC servo motor manufactured by Sanyo Denki for the P8 Super BL Servo Motors series. Its permanent-magnet excitation and internal holding brake allow it to maintain shaft position when power is off, a function often required on vertical axes or indexing tables. A 220 mm square flange simplifies mounting to large gearboxes, while the 50 mm shaft diameter transfers torque directly to couplings without intermediate bushings. When paired with a matching drive, the motor provides responsive speed and position control. It is suitable for packaging lines, machine tools, and automated storage modules.
The continuous operating point is based on a rated output of 4.5 kW, which is the mechanical power the motor can deliver without exceeding its thermal limits. At a rated speed of 2,000 rpm, that power corresponds to a shaft torque of 21.5 N·m, indicating the available steady-state load capacity. The winding draws a rated current of 24.1 A RMS, so drives and cabling must accommodate that current level. An enclosure rating of IP67 protects the stator windings from dust ingress and allows temporary immersion, expanding installation options on washdown or outdoor machinery. The phase resistance is only 0.043 Ω, which minimizes resistive losses and helps control temperature rise during normal duty cycles.
Dynamic operation includes a peak stall torque of 70.0 N·m, and this short-term limit supports rapid acceleration or disturbance rejection when commanded by the drive. The electrical time constant of 33 ms indicates how quickly the stator current approaches its target value, affecting the current-loop bandwidth in the controller. Rotor inertia is 58.1 × 10⁻⁴ kg·m², providing a balance between responsive motion and load matching on heavier mechanisms. The torque constant is 1.05 N·m/A RMS, providing a direct conversion between commanded current and generated torque. This relationship helps the drive regulate motor output accurately as operating loads and motion commands change.
