Product Description:

The P50B05020DXS20 is a compact brushless AC motor produced by Sanyo Denki within the P5 Super BL Servo Motors series. Designed for positioning and speed-regulated axes, the unit converts drive current into precise mechanical rotation for pick-and-place heads, conveyors, and small spindle stations. Its feedback encoder and low rotor inertia allow the controller to close the loop quickly, so automated machinery can follow demanding motion profiles with minimal overshoot. The motor mounts with a square flange and connects to Sanyo Denki P5 amplifiers as a matched actuation pair.

At standstill, the stator can deliver a continuous torque of 0.686 N·m, allowing the axis to hold a load without overheating. The electric time constant of 2.9 ms indicates how quickly the phase current reaches its commanded value, and the short response helps reduce control lag. An optical encoder supplies 2,000 pulses per revolution, so the drive receives 8,000 counts per revolution after quadrature decoding, improving small-angle interpolation. The maximum speed reaches 4500 rpm, allowing higher operating speeds when sufficient torque remains available. The phase resistance is 3.4 Ω, which affects amplifier current and the resistive losses dissipated in the windings.

During rated operation, the shaft supplies 200 W of mechanical power at 3000 rpm with a rated torque of 0.637 N·m. An instantaneous stall capacity of 1.96 N·m is available for rapid acceleration phases before the thermal model limits current. The housing meets IP55, limiting harmful dust ingress and tolerating low-pressure water jets when the motor is installed in general factory environments. A mechanical time constant of 0.9 ms and a rated power rate of 24.2 kW/s indicate that the rotor can reverse direction quickly without generating excessive heat. A shaft seal preserves the enclosure protection at the output coupling. The square mounting face measures 54 mm, providing a compact footprint for installation in space-constrained machinery.
