Product Description:

Sanyo Denki produces the P50B05020PXS00 as part of its P5 Super BL Servo Motors series. This standard brushless AC servo motor is intended for precise velocity and torque control in positioning tables, pick-and-place axes, and other industrial automation equipment. Its wiring-saving incremental encoder supplies real-time rotor feedback to the drive while minimizing the number of required cables. The brushless design also eliminates the wear associated with motor brushes during frequent operating cycles.

At its continuous operating point, the unit supplies 200 W at a rated speed of 3000 rpm, producing 0.637 N·m of torque while drawing 3.4 Arms. The magnetic circuit supports speeds up to 4500 rpm, and the shaft can produce a peak torque of 1.96 N·m during short acceleration periods. The motor supports axis inertias up to 1.73 × 10⁻⁴ kg·m², allowing the reflected load to be matched to the drive capacity for stable control. Rotor inertia is 0.173 × 10⁻⁴ kg·m², which supports rapid acceleration and controlled deceleration. The incremental encoder provides 2,000 pulses per revolution, and its single-cable format reduces the required connector count.

The motor has a 54 mm square flange, an 8 mm shaft, and an overall length of 105 mm. Its frame weighs 1.07 kg, reducing cantilever stress on compact linear stages. The winding has a phase resistance of 0.85 Ω and a torque constant of 0.218 N·m/Arms, allowing the drive to calculate current demand and manage winding heat. During transient operation, the winding can draw up to 11 Arms of current without demagnetization. The motor is supplied without a holding brake, so an external clamping mechanism is required when a vertical axis must remain stationary after power is removed.
