Product Description:
The P50B05010DXS79 is a brushless AC servo motor produced by Sanyo Denki within the P5 Super BL Servo Motors series. A wiring-saving incremental encoder relays rotor position data over the power leads, eliminating the need for a separate feedback cable and simplifying cabinet wiring. Intended for compact pick-and-place axes, indexing tables, and labeling heads, the motor converts regulated drive current into precise rotation while maintaining small overall frame dimensions for space-constrained automation.
At its continuous operating point, the unit delivers a rated output of 100 W, converting electrical energy into mechanical work for light-duty motion. A rated torque of 0.319 N·m is maintained at the rated speed of 3000 rpm, allowing steady velocity control without thermal derating. The enclosure meets an ingress protection rating of IP55, protecting the windings from dust and water jets. A standardized 54 mm square flange aligns with small gearboxes or mounting brackets. At the rated operating point, the armature draws 1.1 A RMS, while a power rate of 10.6 kW/s supports rapid energy delivery. Continuous stall torque reaches 0.353 N·m, and the mechanical time constant of 1.4 ms supports quick acceleration. The motor has no holding brake, so an external mechanism may be required to secure a stationary load when power is removed. Peak stall current is limited to 3.7 A RMS during brief overloads.
For startup and static load release, the motor tolerates a continuous stall current of 1.2 A RMS and can supply a peak stall torque of 0.98 N·m. Commanded speed extends to 4500 rpm, providing additional headroom above the rated operating point while the controller supervises thermal limits. The three-phase stator has a phase resistance of 4.9 Ω, which works with an electrical time constant of 2.5 ms to govern current rise during transient operation. A torque constant of 0.319 N·m/A RMS allows the drive to calculate torque output from measured phase current, supporting precise current-loop control in servo applications.
