Product Description:

The P30B08075DXD500G is a brushless AC servo motor built by Sanyo Denki for the P3 Super BL Servo Motors series. As a compact rotary actuator, it converts drive current into controlled shaft torque and speed, allowing machine tools, pick-and-place gantries, and packaging lines to position loads with high repeatability. Within an automation cell, the motor pairs with a matched amplifier and feedback system to close both velocity and position control loops for precise motion profiles.

At stall, the motor can deliver a continuous torque of 2.55 Nm without exceeding its thermal limit, providing a steady holding force for static axis loads. The rotor reaches the commanded speed quickly because the mechanical time constant is only 0.3 ms, so acceleration transients remain short. Under rated operating conditions, the shaft outputs 750 W at 3000 rpm, combining moderate power density with the mid-speed capability common to servo presses and indexing tables. Peak-load events can draw up to 15.0 Arms, so the selected drive must accommodate this current. Copper losses are governed by a phase resistance of 0.52 Ω, and the back electromotive force rises linearly with speed at an induced voltage constant of 19.74 mV/rpm; these parameters support current-loop tuning and bus voltage selection.

During short bursts, the shaft can supply a peak stall torque of 7.15 Nm, allowing the axis to overcome breakaway friction or rapid load reversals. At rated load, the phase current levels off at 4.6 Arms, producing a continuous running torque of 2.38 Nm while keeping the winding temperature within its design limits. The torque constant of 0.565 Nm/Arms expresses the proportional relationship between commanded current and generated torque, simplifying feedforward control in servo loops. A rotor inertia of 0.635 × 10⁻⁴ kg·m² minimizes overshoot, allowing tight positioning with modest gain settings.
