Product Description:

The KB506XS0 is a DC brush servo motor produced by Sanyo Denki for the K SANMOTION Servo Motors series. In automated pick-and-place units, small gantries, and semiconductor handlers, the motor converts drive current into precise rotary motion for closed-loop position control. Its 54 mm square flange allows direct mounting to compact gearheads without requiring a large machine interface. Low rotor inertia supports the rapid acceleration and deceleration commonly required by high-cycle industrial equipment.

The electrical section is designed for a 24 V bus and draws up to 3.9 A while operating at rated load. A winding resistance of 1.1 Ω governs current rise during startup, while an inductance of 0.5 mH affects the current ripple regulated by the servo drive. Continuous mechanical output reaches 60 W, and the motor has a torque constant of 0.057 N·m/A. In velocity mode, the drive compensates for back electromotive force according to a voltage constant of 6.0 × 10⁻³ V/rpm. These electrical characteristics support responsive control of light-duty axes during frequent starts, stops, and direction changes.

The motor produces a shaft torque of 0.19 N·m at its rated speed of 3000 rpm and can reach a no-load speed of 5000 rpm for transient movement. Its rotor inertia is 0.22 × 10⁻⁴ kg·m², which helps limit overshoot during rapid positioning, while the complete motor weighs 0.80 kg. A built-in incremental encoder supplies 2000 pulses per revolution, allowing the motion controller to resolve 0.18 degrees per count. The enclosure has an IP43 protection rating, so the motor tolerates most workshop dust but should remain protected from direct water spray. The compact housing and encoder resolution suit indexing tables, miniature linear stages, and vision-guided actuators that require accurate movement within limited installation space.
