Product Description:

The P50B08050DXS0E is a brushless AC servo motor manufactured by Sanyo Denki for the P5 Super BL Servo Motors series. It is intended for industrial automation tasks that require precise position or velocity control, such as indexing tables, electronic camming, and small transfer axes. Its permanent-magnet construction and electronically commutated windings supply continuous torque without brush wear, allowing the motor to operate as a compact, low-maintenance actuator that couples directly to gearheads or belt drives.

The motor sustains a continuous shaft load of 1.96 N·m while drawing 4.5 Arms at stall, and its rated operating point delivers 1.589 N·m with 3.9 Arms. A torque constant of 0.473 N·m/Arms links current output from the amplifier to mechanical torque, simplifying control-loop tuning. For rapid indexing, the stator can momentarily accept a peak current of 15.0 Arms, producing a peak stall torque of 5.88 N·m. The electrical time constant is 5.2 ms, while the mechanical time constant is 1.5 ms, so current and speed settle rapidly after command changes. The rated power rate is 21.8 kW/s, and the rotor inertia is 1.161 × 10⁻⁴ kg·m², balancing responsiveness with load tolerance. Phase resistance is 0.94 Ω. Class F insulation permits winding temperatures up to 155 °C.

Physical integration is aided by a flange that matches 80 or 86 mm mounting patterns, an overall length of 126 mm, and a sealed housing with an IP55 rating for protection against dust and water jets. The maximum speed reaches 4500 rpm, enabling high feed rates when the motor is paired with appropriate gearing. The brushless motor is not equipped with a holding brake, so static load retention must be supplied externally. An incremental encoder uses reduced wiring for feedback connections, while phase-to-phase insulation and standard thermal sensors provide additional protection during operation.
