Product Description:
The P50B07040HXS3B servo motor is produced by Sanyo Denki for the P5 Super BL Servo Motors series. This brushless unit converts electrical energy from a compatible drive into controlled mechanical rotation for positioning, indexing, and speed-regulated axes in automated machinery. Its permanent-magnet excitation system supports responsive torque control across repetitive motion cycles. The motor provides continuous torque for conveyors, pick-and-place arms, indexing tables, and similar industrial automation equipment.
The housing has a fully enclosed, self-cooling design, so ambient air passes over the finned frame without circulating through the motor. This arrangement protects the stator windings from airborne contaminants and eliminates the need for an internal fan. At a rated output of 400 W, the shaft maintains a constant speed of 3000 rpm during continuous operation, making the motor suitable for high-speed positioning tasks. The motor operates from a three-phase 200 VAC supply that is compatible with Sanyo Denki P5 servo amplifiers. A rear-mounted wiring-saved incremental encoder provides a feedback resolution of 2000 P/R, allowing the drive to command shaft increments as small as 0.18 degrees. The frame has an IP55 protection rating, which guards against dust and water jets encountered in industrial production areas.
The electrical insulation system withstands a dielectric test of 1500 VAC for one minute, helping protect the windings under demanding electrical conditions. Insulation resistance remains above 10 MΩ at 500 VDC, supporting dependable operation during repetitive thermal cycles. A flange dimension of 76 mm provides a compact mounting interface for installation on compatible machine frames. An integral shaft seal restricts the entry of oil or coolant along the output shaft and protects the internal bearings from contamination. The motor meets vibration grade V15, limiting excessive rotor displacement during operation. It is supplied without a holding brake and is rated for continuous duty, so vertical loads require external mechanical retention when drive torque is unavailable.
