Product Description:
The P50B07030DXSS1 is a brushless servo motor built by Sanyo Denki and supplied in the P5 Super BL Servo Motors series. This permanent-magnet unit is intended for industrial positioning and speed-control tasks where compact size and fast dynamic response are required. Its wire-saving incremental encoder allows the drive to read rotor position through a single cable, simplifying wiring in automated machinery and reducing the number of separate connections required between the motor and drive.
The square front flange measures 76 mm, making the motor suitable for mid-frame gearboxes and direct-coupled loads. When driven from a 200 VAC supply, it produces a continuous mechanical output of 300 W at a rated speed of 3,000 rpm, corresponding to a continuous torque of 0.931 N·m. Its maximum rotational speed reaches 4,500 rpm, so indexing sequences can finish quickly without requiring an oversized drive. The electrical time constant of 3.8 ms and the mechanical time constant of 1.8 ms work together to provide rapid current rise and rotor acceleration, while a phase resistance of 2.9 Ω balances current draw against heat generation. Because no holding brake is fitted, external clamping or drive torque must secure vertical axes during a power loss. A rotor inertia of 0.495 × 10⁻⁴ kg·m² supports tight control-loop gains without introducing oscillations, and the static stall torque is 0.98 N·m for low-speed holding while the motor remains energized.
An IP55 enclosure protects the stator against dust and low-pressure water jets commonly encountered on factory floors. Encoder feedback is delivered at 2,000 P/R, giving the controller 8,000 counts per revolution when quadrature decoded for precise position interpolation. Peak stall torque reaches 2.94 N·m, allowing short bursts of load acceleration before thermal limits intervene. The torque constant is 0.483 N·m/Arms, which allows the drive to calculate phase current directly from the commanded torque. A rated power rate of 17.7 kW/s supports rapid acceleration during repetitive motion cycles, while the brushless design reduces maintenance by eliminating components that would otherwise wear through mechanical contact.
