Product Description:
The P50B08050DXS00M is a brushless AC servo motor produced by Sanyo Denki within the P5 Super BL Servo Motors series. In automated machines, it pairs with a matched amplifier to drive positioning axes, delivering closed-loop rotation wherever compact power and torque are required. Its compact design supports precise motion in packaging equipment, assembly systems, material-handling machines, and other applications that require responsive axis control.
At its nominal operating point, the motor supplies 500 W of mechanical power while turning at 3,000 rpm. This operating point provides a rated torque of 1.589 N·m with a rated current of 3.9 Arms. The electromagnetic coupling efficiency is characterized by a torque constant of 0.473 N·m/Arms, so each ampere delivered by the drive produces nearly half a newton-meter of shaft torque. A phase resistance of 0.94 Ω limits copper losses at the rated current, while the brushless design eliminates mechanical commutator wear during extended duty cycles. Feedback is provided by a wiring-saving incremental encoder that produces 2,000 pulses per revolution, giving the controller fine position resolution without additional sensor cabling. The motor carries CE and UL approvals for use in European and North American installations.
The motor reaches a maximum no-load speed of 4,500 rpm, allowing rapid traverse moves before the axis settles at its commanded position. The magnetic circuit can sustain a continuous stall torque of 1.96 N·m and a peak stall torque of 5.88 N·m, providing additional capacity for acceleration and disturbance rejection. The laminated rotor has an inertia of 1.161 × 10⁻⁴ kg·m², balancing quick response with stable operation when coupled to medium-mass loads. The motor has an 80/86 mm square flange, a 16 mm keyed shaft, and an overall body length of 126 mm for integration into compact machinery. The assembly weighs 3.0 kg and is supplied without a holding brake, so stationary load retention must be provided by motor torque or an external mechanism when required.
