Product Description:

The KB506JS0 is a permanent-magnet servo motor produced by Sanyo Denki within the K SANMOTION Servo Motors series. Intended for light-duty positioning axes in automated equipment, it converts regulated armature current into rotational motion that can be indexed or velocity-controlled by a matched drive. The 54 mm square mounting flange simplifies integration inside compact machinery, and the 1.42 kg housing keeps moving mass low for pick-and-place heads, vision stages, and other precision actuators.

The motor operates at a rated armature voltage of 24 V. At this voltage, the shaft reaches a rated speed of 3000 rpm and delivers 0.06 kW of mechanical power. Continuous stall torque is 0.24 N·m, and the corresponding armature stall current is 4.5 A, indicating the thermal limit for steady static loads. A torque constant of 0.057 N·m/A links each ampere of phase current to proportional torque, allowing the drive to predict output force without additional sensors. Feedback is provided by a line-driver encoder output circuit that maintains differential signals for noise immunity along extended cable runs. Because the windings are optimized for a low-voltage bus, the motor suits mobile or battery-powered platforms that cannot accommodate higher supply voltages.

For transient moves, the winding tolerates a peak current of 31 A, producing up to 1.8 N·m of stall torque. An integral holding brake supplies 0.29 N·m of static torque, so vertical or cantilevered loads remain fixed when motor power is removed. The incremental encoder offers a resolution of 2000 P/R, giving controllers fine positional granularity for precise indexing. Rotor inertia of 0.22 × 10⁻⁴ kg·m² supports quick acceleration without excessive overshoot. The compact brake mechanism adds minimal length, preserving installation depth in space-constrained assemblies.
