Product Description:
The P50B04006DCS6F is a brushless AC motor manufactured by Sanyo Denki for the P5 Super BL Servo Motors series. Designed for positioning tables, pick-and-place heads, and similar light-duty axes, the unit couples a compact rotor with an integrated electromagnetic brake. The motor converts drive current into precise rotary torque and returns shaft-position data through a wire-saving incremental encoder. This feedback allows the controller to close the speed and position loops without requiring additional sensor wiring. The compact design is suitable for automated equipment where installation space is limited and rapid, controlled movement is required.
The brake circuit draws 0.26 A at a fixed 24 V when engaged, and it can hold the shaft with 0.191 N·m of torque while adding only 0.24 kg to the assembly. The armature reaches its rated current in 1.4 ms, allowing the servo to respond rapidly to command changes. Mounting uses a square flange measuring 40 or 42 mm, allowing the motor to fit compatible machine frames. Under light load, the rotor can accelerate to 4500 rpm, while its continuous operating speed is 3000 rpm. Load inertia is limited to 0.054 × 10⁻⁴ kg·m², which helps reduce overshoot during frequent start-and-stop cycles. The brushless configuration eliminates commutator wear and reduces routine maintenance requirements.
The phase windings have a resistance of 10.4 Ω, which affects current draw and supports proper drive selection. During steady operation, the stator carries 0.7 A RMS and produces 60 W of mechanical power. The magnetic circuit provides a stall torque of 0.647 N·m for brief periods of elevated load. The torque constant is 0.304 N·m/A RMS, supporting efficient conversion of motor current into mechanical torque. A mechanical time constant of 1.6 ms helps keep speed transients short during rapid positioning cycles. The integrated holding brake secures vertical loads when the axis is stationary, reducing the risk of unintended movement. Its compact mass and fast electrical response suit applications that require frequent acceleration, controlled deceleration, and accurate positioning within a small machine envelope.
