Product Description:

The KB506TXX is a compact permanent-magnet DC servo motor produced by Sanyo Denki as part of the K SANMOTION Servo Motors series. It converts low-voltage electrical input into precise mechanical rotation. This operation enables compact tooling, small conveyors, and light robotic joints to follow position or velocity commands in industrial automation applications where size and weight are tightly constrained.

The motor is optimized for low-voltage motion buses. It operates at a rated armature voltage of 24 VDC and draws a steady-state armature current of 3.9 A. With these inputs, the machine delivers a mechanical output of 60 W. The shaft operates at 3000 rpm while producing a continuous working torque of 0.19 N·m. These values allow the unit to drive small lead screws, belt stages, or miniature pumps without gearbox multiplication. The electrical load matches the capacity of common 5 A-class servo amplifiers, so wiring can remain thin and connector footprints can remain small. Efficiency within this range also keeps the thermal rise manageable when the motor runs at its nominal rating for extended periods.

During dynamic peaks, the rotor can sustain a stall torque of 1.8 N·m, providing headroom for load spikes or acceleration ramps, whereas the continuous stall rating is 0.24 N·m for static holding. Current dynamics are shaped by an armature inductance of 0.5 mH and a winding resistance of 1.1 Ω, allowing the drive to regulate current precisely while minimizing copper loss. The motor has a torque constant of 0.057 N·m/A, and its low rotor inertia of 0.22 × 10⁻⁴ kg·m² supports fast cycle times with minimal servo overshoot. An internal tachometer generates 7 × 10⁻³ V per rpm, with a tolerance of ±10%, across a 10 kΩ load for analog speed feedback. The 54 mm square flange and 1.00 kg mass simplify installation on lightweight aluminum frames.
