Product Description:

The P50B04006DXS4E is a brushless servo motor from Sanyo Denki developed within the P5 Super BL Servo Motors series. In positioning stages, pick-and-place arms, and other compact machinery, the motor converts drive current into precise rotary motion for feedback-controlled automation tasks. The motor uses a wiring-saving incremental encoder for position detection, providing angular feedback without separate sensor cabling. Its compact design supports applications where controlled movement and efficient use of installation space are important.

At stall, the motor draws a continuous phase current of 0.76 Arms and produces a steady torque of 0.216 N·m; it can maintain these operating levels without overheating. At its rated operating point, the shaft delivers 60 W, while the armature voltage drop is governed by a winding resistance of 10.4 Ω. An electrical time constant of 1.4 ms indicates how quickly the current rises toward its commanded level, supporting rapid closed-loop torque adjustments. The torque constant is 0.304 N·m/Arms, so each ampere of phase current generates approximately one-third of a newton-meter of torque. The rated armature current is 0.7 Arms and corresponds to a rated torque of 0.191 N·m.

During short periods of high demand, the instantaneous stall current can reach 2.7 Arms and produce a peak torque of 0.647 N·m. The mechanical time constant is 1.6 ms, supporting responsive acceleration when the connected load permits rapid movement. The nominal speed is 3000 rpm, and the rotor can reach a maximum speed of 4500 rpm when commanded, with a rated power rate of 7.5 kW/s. Because the motor does not have a holding brake, an external mechanism must secure vertical loads when power is removed. A flange measuring 40 or 42 mm supports mounting in compact machine frames, while the brushless design reduces maintenance requirements. The motor has an IP40 protection rating, so its housing resists solid objects larger than 1 mm but requires installation in a clean, dry enclosure.
