Product Description:

The P30B08075DXS48 is a brushless AC servo motor produced by Sanyo Denki within the P3 Super BL Servo Motors series. Designed as a rotary actuator for industrial automation, it couples to precision gearboxes or belt drives and provides closed-loop motion when powered by a compatible amplifier. The motor’s magnetic circuit and encoder package support accurate velocity and position regulation, making the unit suitable for pick-and-place machines, indexing tables, and other equipment that requires repeatable servo performance.

The motor has a rated mechanical output of 750 W for continuous operation. It delivers this output while the shaft turns at 3,000 rpm and produces a rated torque of 2.38 N·m. To maintain that workload, the drive must supply an RMS phase current of 4.6 A, which corresponds to a torque constant of 0.565 N·m/A rms. The power rate is 92.0 kW/s, indicating how rapidly the motor can exchange kinetic energy during acceleration and deceleration. A phase resistance of 0.52 Ω contributes to copper losses, while the electrical time constant of 8.3 ms indicates how quickly current rises in the windings. The induced voltage constant is 19.74 mV per rpm with a tolerance of ±10%, providing the back electromotive force value needed when selecting a suitable drive voltage.

For static loads, the motor can sustain a continuous stall torque of 2.55 N·m. During brief startups, it accepts an instantaneous stall torque of 7.15 N·m when the controller supplies up to 15.0 A rms. Its peak mechanical speed reaches 4,500 rpm, and a mechanical time constant of 0.3 ms supports rapid responses to command changes. The brushless design reduces maintenance requirements, while the wiring-saving incremental encoder provides 2,000 pulses per revolution for position and velocity feedback without additional encoder wiring. An 80 or 86 mm flange supports attachment to compatible metric frames, and the absence of a holding brake reduces the motor’s overall length and rotational inertia.
