Product Description:

The P50B03003PXS22 is a brushless servo motor produced by Sanyo Denki within the P5 Super BL Servo Motors series. As a compact 30 W axis actuator, it converts drive current into precise shaft motion for positioning tables, pick-and-place heads, and other small automation mechanisms. The motor is supplied without a holding brake, so any static load must be secured through drive torque or external clamps. A wire-saving incremental encoder relays position feedback to the controller, maintaining closed-loop accuracy during rapid velocity and torque changes.

At a rated output of 30 W, the unit supplies continuous mechanical power suitable for light loads such as indexing grippers or micro-conveyors. The corresponding rated phase current is 1.0 A rms, allowing low-capacity amplifiers to power the axis without oversizing. An encoder resolution of 2,000 P/R provides small detectable angular increments, supporting smooth interpolation at high command rates. The square mounting interface uses a 35 mm flange that aligns directly with miniature gearheads or stage plates. For brief overloads, the winding can accept a peak stall current of 3.6 A rms, generating extra torque to overcome static friction. The phase resistance is 5.4 Ω, which matches the thermal design of the drive and limits resistive losses during steady-state operation.

An electrical time constant of 0.7 ms and a mechanical time constant of 2.0 ms indicate that current and speed settle quickly after command steps, enabling tight positioning loops in pick-and-place or inspection cells. The rotor and stator achieve a power rate of 6.5 kW/s, so the motor can accelerate its load rapidly without prolonged thermal buildup. With the total mass held to 0.24 kg, the assembly imposes a minimal inertial penalty on moving axes, preserving throughput in high-cycle equipment. The brushless design eliminates commutator wear and works with the wire-saving feedback detector to reduce maintenance while providing precise digital commutation.
