Product Description:

The P50B03003DCS00 is a brushless servo motor manufactured by Sanyo Denki for the P5 Super BL Servo Motors series. With a 35 mm square flange and a compact 98 mm overall length, the unit provides precise rotary actuation for positioning tables, compact gantries, and laboratory mechanisms. A reduced-wiring incremental encoder is built into the rear housing, minimizing feedback cabling, while an integrated holding brake maintains the shaft position whenever control power is absent.

During continuous operation, the motor delivers 30 W of mechanical power while generating a rated torque of 0.098 N·m at a shaft speed of 3000 rpm. Supplying this load requires 0.5 A rms from the drive, allowing the motor to operate with a compact amplifier. The encoder provides a resolution of 2000 P/R, enabling the controller to command increments as fine as 0.18 degrees. Its data channel shares the power harness, reducing the amount of wiring required between the motor and controller. The brake circuitry draws 0.25 A at 24 V and clamps the rotor with sufficient holding torque to keep vertical axes stationary during emergency-stop events. A 5 mm shaft transfers the motor’s output through standard couplings.

For short operating intervals, the rotor can accelerate to 4500 rpm and withstand a peak stall torque of 0.323 N·m, providing additional capacity for rapid indexing or overcoming static friction. Dynamic response is supported by a mechanical time constant of 2.1 ms and an electrical time constant of 0.7 ms, so commanded current changes translate quickly into torque. The motor has a torque constant of 0.206 N·m/A rms, allowing the drive to estimate torque output accurately as current changes. The compact flange, short housing, and narrow shaft make the motor suitable for equipment with limited mounting space, while the fast response supports smooth motion under changing inertia.
