Product Description:

Sanyo Denki manufactures the P30B04005DXS00 as part of its P3 Super BL Servo Motors series. This brushless AC servo motor is intended for precision positioning and velocity control in compact automation stages, small gantries, and feeder mechanisms. A 40 mm class mounting flange allows direct coupling to miniature gearheads, while the wiring-saving incremental encoder transmits position feedback over the power harness, reducing the connector count in space-limited enclosures. By combining rare-earth magnets with low-loss laminations, the unit supplies responsive torque without adding unnecessary mass to moving axes.

Continuous operating data establish the electrical operating range of this model. A rated mechanical output of 50 W is delivered at the rated shaft speed of 3,000 rpm, producing a steady torque of 0.157 N·m when the drive supplies 0.74 Arms. The torque constant is 0.235 N·m/Arms, so the controller can calculate output torque directly from phase current. A built-in feedback device supplies 2,000 pulses per revolution, supporting precise sub-degree positioning. With an electrical time constant of 1.2 ms and a phase resistance of 9.1 Ω, current rises quickly while remaining compatible with low-power inverter stages. The motor’s power rate of 9.3 kW/s indicates how quickly it can exchange energy during rapid acceleration or deceleration cycles.

The shaft can reach a maximum speed of 4,500 rpm for short periods, and a maximum stall torque of 0.49 N·m allows the axis to resist transient loads without moving. Mechanical response is aided by a rotor inertia of 0.031 × 10⁻⁴ kg·m² and a mechanical time constant of 1.3 ms, providing fast reversal capability. The motor has an overall length of 70 mm. Its mass is only 0.35 kg, which helps keep moving assemblies lightweight. The motor has a standard design without a holding brake, so an external restraint is required to secure the load when power is removed.
