Product Description:

The P50B07040DXS50 is a servo motor built by Sanyo Denki for the P5 Super BL Servo Motors series. It uses brushless technology and an incremental encoder with simplified wiring to provide closed-loop control in pick-and-place arms, packaging machines, and other automation equipment that requires quick acceleration and precise position feedback. The motor’s 76 mm flange allows direct mounting to compact gearheads or couplings without additional adapters, and the lack of a holding brake keeps its overall length and mass low for lightweight axes.

The motor provides a rated output of 400 W continuously at a rated speed of 3,000 rpm. At that operating point, the shaft produces a rated torque of 1.274 N·m while drawing a rated current of 3.0 A rms from the drive amplifier. Copper losses are associated with a winding resistance of 1.65 Ω, making the thermal rise at nominal load predictable and simplifying cabinet ventilation planning. A 2,000-pulse-per-revolution encoder sends position data to the controller, while the rotor inertia of 0.74 × 10⁻⁴ kg·m² helps the servo follow rapid command changes without excessive overshoot. The phase inductance and winding resistance result in an electrical time constant of 4.0 ms. This response is suitable for operation with many mid-power digital drives.

When stationary, the motor can hold loads with a continuous stall torque of 1.372 N·m. It can tolerate brief overloads up to a peak stall torque of 3.92 N·m during startup or shock events. Speed setpoints can be increased to a maximum of 4,500 rpm for high-throughput cycles, and the motor has a torque constant of 0.481 N·m/A rms. A mechanical time constant of 1.6 ms indicates that the rotor can accelerate quickly in applications with frequent speed changes. The brushless design eliminates commutator wear and reduces the amount of routine maintenance associated with mechanical electrical contacts.
