Product Description:

The P50B07030DXSGZM is a brushless AC servo motor produced by Sanyo Denki within the P5 Super BL Servo Motors series. It is intended for precision positioning and velocity control in automated machinery. The motor connects directly to matched P5 drives to actuate robot joints, pick-and-place slides, and compact conveyor sections on automated assembly lines.

The motor delivers a continuous mechanical output of 300 W at a rated speed of 3,000 rpm while drawing 2.2 A rms per phase. At that operating point, it supplies 0.931 N·m of torque, producing a favorable power-to-size ratio for mid-frame axes. An enclosure rating of IP55 protects the stator against dust and low-pressure water jets encountered in factory washdown areas. Internally, the windings have a phase resistance of 2.9 Ω and a torque constant of 0.483 N·m/A rms, providing linear torque development. The electrical time constant is 3.8 ms, while the mechanical time constant is 1.8 ms, supporting rapid current rise and rotor acceleration. Position feedback comes from a wiring-saving incremental encoder with a resolution of 2,000 pulses per revolution. The design carries CE and UL certifications for compliance with common installation requirements.

The shaft can reach a maximum speed of 4,500 rpm, and the motor can produce a short-term stall torque of 2.94 N·m. The square mounting face measures 76 mm, allowing direct coupling to gearboxes or linear stages. Rotor inertia is 0.495 × 10^-4 kg·m², and the complete unit weighs 1.71 kg, minimizing moving mass on gantry or robotic arm structures. The motor has no holding brake, so an external clamping device is required to retain a load when power is removed. Its power rate is 17.7 kW/s, supporting rapid acceleration during frequent start-and-stop cycles. The incremental encoder supplies position feedback throughout these cycles, while the brushless design avoids the wear and electrical noise associated with mechanical commutation.
