Product Description:

The P50B03003DXS2B is a brushless servo motor manufactured by Sanyo Denki for the P5 Super BL Servo Motors series. Intended for compact automation axes, it converts electrical energy into controlled rotary motion while its wiring-saving incremental encoder supplies real-time position feedback. The device supports precise speed and torque control in pick-and-place, inspection, and laboratory equipment where space and weight are limited.

During continuous operation, the motor produces 30 W at a rated shaft speed of 3000 rpm. This operating point corresponds to a continuous torque of 0.098 N·m, while each phase draws 0.5 Arms. A torque constant of 0.206 N·m/Arms links commanded current directly to developed torque, simplifying closed-loop tuning in small drives. The 2000 P/R encoder delivers quadrature signals for 0.18-degree resolution, and a 0.7 ms electrical time constant allows current to rise quickly for responsive servo operation. With a 2.1 ms mechanical time constant, the rotor accelerates rapidly to support high-cycle equipment. A 35 mm square flange and 5 mm shaft accommodate miniature couplings, while the 67.5 mm overall length allows installation inside slender machine frames. The motor is supplied without a holding brake, which reduces rotor inertia.

For short bursts, the drive can deliver a peak stall torque of 0.323 N·m, enabling rapid indexing or quick settling against external loads. The maximum permissible speed reaches 4500 rpm, providing operating headroom above the rated speed when faster motion is required. A phase resistance of 20.5 Ω limits current draw from compact power supplies, and the motor has a total mass of 0.24 kg. Its low mass reduces the load placed on compact mounting structures and small moving assemblies. Brushless construction reduces routine maintenance associated with mechanical commutation components. The encoder uses a single-cable interface to reduce wiring within space-constrained machinery.
