Product Description:

The P30B08075DXS00E is a brushless servo motor built by Sanyo Denki within the P3 Super BL Servo Motors series. It supplies rotary power for positioning axes and speed-regulated conveyors in automated equipment. A wiring-saving incremental encoder with 2,000 pulses per revolution is integrated for feedback, and the motor carries CE marking for use in regulated installations. Its standard construction, 80/86 mm flange, and total length of 140 mm allow the unit to mount directly to gearboxes or machine frames without adapters.

The motor is rated for an output of 750 W. Under continuous duty, the shaft turns at 3000 rpm while producing 2.38 N·m of torque, and this operating point is reached with a phase current of 4.6 A rms. The internal copper windings and insulation are matched to a line-to-line resistance of 0.52 Ω, a value that influences heat rise during steady-state current flow. A torque constant of 0.565 N·m/A rms relates current commands from the servo amplifier to the motor’s mechanical output. An electrical time constant of 8.3 ms indicates how quickly the winding current settles after a step change. The continuous stall torque is 2.55 N·m, providing additional capacity for holding static loads without shaft movement.

Dynamic events are supported by a peak stall torque of 7.15 N·m and a momentary winding current limit of 15.0 A rms. These ratings accommodate rapid acceleration and brief shock loads without demagnetizing the rotor. Rotor inertia is 0.635 × 10⁻⁴ kg·m², enabling fast response while still smoothing minor load variations. The maximum mechanical speed reaches 4500 rpm for short intervals, extending the usable speed range above the rated operating point. The motor weighs 3.3 kg and is supplied without a holding brake, so external holding equipment may be required when a stationary load cannot be retained by motor torque. Its brushless design eliminates commutator wear during extended service periods.
