Product Description:

The P50B03003DXLBF is a brushless servo motor manufactured by Sanyo Denki for the P5 Super BL Servo Motors series. As a compact rotary actuator, it delivers closed-loop motion for small pick-and-place axes, indexing tables, and laboratory devices that need accurate torque and speed control in industrial automation. The unit comes without a holding brake, favoring applications where external clamping or continuous drive torque maintains the load position.

This model operates from a supply of 200 VAC and converts that input into a rated mechanical output of 30 W. At its rated operating point, the shaft turns at 3000 rpm while developing 0.098 N·m of torque, making the motor suitable for light mechanical loads driven through a 5 mm shaft. The motor face follows the JIS 35 mm square pattern, so the mounting flange measures 35 mm across and aligns with miniature gearheads or brackets. Internally, a phase resistance of 20.5 Ω and a torque constant of 0.206 N·m/Arms govern electrical-to-mechanical conversion, while the rated armature current is 0.5 Arms. Rapid current establishment is supported by an electrical time constant of 0.7 ms, while the mechanical time constant of 2.1 ms supports quick speed response. A stall armature current of 0.53 Arms indicates the current level at standstill, and the brushless design eliminates commutator wear.

The motor reaches a maximum velocity of 4500 rpm for short duty cycles, and its continuous stall capability is 0.108 N·m, supporting low-speed operation under a continuous load. During peak loading, the rotor can deliver up to 0.323 N·m while drawing a maximum stall current of 1.8 Arms from the drive amplifier. These peak values help with drive sizing so current limiters and thermal models can protect the motor from excessive loading. The 5 mm shaft diameter simplifies coupling to timing pulleys. Brushless motor technology also keeps cogging low for smooth motion trajectories in precision equipment.
