Product Description:
The P50B05005DXS11 belongs to the P5 Super BL Servo Motors series manufactured by Sanyo Denki. As a brushless unit built for closed-loop motion systems, it converts drive current into controlled rotary power so that indexing tables, pick-and-place heads, or light conveyors achieve repeatable positioning under PLC command. Its permanent-magnet rotor and incremental feedback allow the connected amplifier to regulate velocity and torque with minimal overshoot during continuous duty cycles.
The armature can maintain a continuous stall torque of 0.167 N·m, which is the maximum torque available at standstill without exceeding the rated temperature. The rated operating point combines a torque of 0.159 N·m with a speed of 3,000 rpm, producing a rated output of 50 W for continuous operation. Shaft position is returned through a 2,000 P/R wiring-saving incremental encoder, reducing the cable count while maintaining fine resolution for servo control loops. The motor attaches with a 54 mm square flange and uses flange mounting to keep the stator concentric with gearboxes or direct-drive loads. A flange seal is present to help protect the motor at its mounting interface. The continuous time rating allows the motor to operate for extended periods when it remains within its rated load and temperature limits.
During rapid moves, the rotor may accelerate to a maximum speed of 4,500 rpm, and transient loading can reach a maximum stall torque of 0.49 N·m without demagnetizing the permanent magnets. The motor has an IP55 ingress protection rating, which protects the enclosure against dust and water jets when the sealing components are installed correctly. The stator windings use Class F insulation to tolerate elevated internal temperatures, while the permanent-magnet excitation system requires no external field wiring. The motor does not include a holding brake, so a vertical axis must use an external mechanical lock to prevent movement when power is removed. Flange mounting supports direct alignment with compact couplings and compatible gearboxes. The incremental encoder supplies the connected servo amplifier with the position information needed for accurate speed correction and repeatable motion.
