Internal Product Review

The P50B05020DXS0E is a Sanyo Denki brushless servo motor with a 200 W rated output. A 3,000 min⁻¹ rated speed and a wiring-saved incremental encoder give the motor precise, responsive motion characteristics. Peak stall torque of 1.96 N·m is a strong technical advantage for demanding servo applications.

Product Description:

The P50B05020DXS0E is a brushless servo motor produced by Sanyo Denki for the P5 Super BL Servo Motors series. Intended for integration with digital amplifiers, it converts electrical command signals into repeatable shaft rotation for small pick-and-place axes, inspection spindles, and indexing equipment. By using permanent-magnet brushless technology, the unit eliminates brush wear and maintains stable performance during continuous industrial automation service. Its compact construction allows installation in applications with restricted space and weight allowances.

During continuous stall, the shaft develops 0.686 N·m, a holding capability that indicates the permissible load when motion is locked. Under rated conditions, the motor delivers 200 W while turning at 3,000 rpm, balancing power output with the available thermal margin. The associated torque of 0.637 N·m is delivered at a phase current of 1.6 Arms, whereas rapid acceleration can draw up to 5.5 Arms. A square mounting face measuring 54 mm matches common compact gearheads and fixture plates. The continuous stall current is 1.7 Arms. An electrical time constant of 2.9 ms governs current rise, while a phase resistance of 3.4 Ω affects drive voltage requirements and heat generation.

The servo’s dynamic behavior is characterized by a mechanical time constant of 0.9 ms and a rotor inertia of 0.173 × 10⁻⁴ kg·m², permitting swift speed transitions without excessive overshoot. When unloaded, the rotor can reach 4,500 rpm, providing additional speed for recovery moves or high-cycle tooling. A torque constant of 0.436 N·m/Arms links controller current commands directly to the delivered torque, simplifying control-loop adjustment. Position information is supplied by a wiring-saving incremental encoder, reducing the number of conductors needed between the motor and amplifier. The motor does not include a holding brake, which reduces its axial length. Its mass is 1.07 kg, supporting installation on compact or weight-sensitive motion axes.
