Product Description:

The P50B04010DCS4E is a compact brushless drive unit produced by Sanyo Denki within the P5 Super BL Servo Motors series. It connects to a matching amplifier to deliver regulated torque and speed for pick-and-place stations, miniature conveyors, and indexing tables. The model is designed for machinery that requires repeatable motion within a compact 40 mm frame, making it suitable for densely arranged industrial automation cells. Its brushless design supports precise operation without the mechanical wear associated with a commutator.

Under rated conditions, the motor delivers 100 W of mechanical output at 3000 rpm, draws 1.0 A RMS from the inverter, and produces 0.319 N·m of continuous torque. The motor has a torque constant of 0.333 N·m/A RMS, allowing the controller to calculate shaft torque from phase current. Continuous stall torque is 0.353 N·m, providing capacity for static loads without overheating. The electrical time constant is 1.5 ms, so current builds quickly as the axis responds to changing force commands. Position data is supplied through a wiring-saving incremental encoder with a resolution of 2,000 pulses per revolution. The encoder shares signal lines with the Hall pattern to reduce wiring bulk. The square flange is available in 40 mm or 42 mm formats for alignment with miniature planetary gearheads.

During intermittent operation, the shaft can accelerate to 4500 rpm, while the magnetic circuit tolerates up to 0.98 N·m of stall torque for short periods before reaching its thermal limits. Phase current can rise to 3.6 A RMS during these brief operating periods. A phase resistance of 7.0 Ω establishes the voltage demand placed on the drive during peak loads. The integrated holding brake operates at 24 V and draws 0.26 A, securing vertical axes when motor power is removed. The small rotor inertia helps reduce settling time during rapid indexing moves, while the brushless construction avoids commutator maintenance.
