Product Description:

The KB406XS0 servo motor is produced by Sanyo Denki for the K SANMOTION Servo Motors series. Intended for low-voltage motion axes in compact packaging machines and laboratory equipment, it converts 24 V DC supply energy into controlled mechanical rotation. The 42 mm flange allows direct mounting to small gearheads or brackets, and the unit weighs only 0.65 kg, minimizing moving mass on lightweight gantries. By supplying precise feedback and rapid torque response, the motor supports repeatable positioning tasks in industrial automation cells.

The armature inductance is 0.5 mH, so current rises quickly and enables tight current loops at the controller. Copper resistance of 0.94 Ω limits resistive losses and helps control the winding temperature during operation. Under rated conditions, the drive electronics deliver 4.1 A at 24 V, producing 0.19 N·m of continuous running torque and a mechanical output of 0.06 kW. The shaft turns at a nominal speed of 3000 rpm, which aligns with common pulley ratios in small transport modules. A torque constant of 0.056 N·m/A translates current commands into predictable torque, supporting responsive acceleration and controlled movement. The motor must be paired with drive electronics suitable for its voltage, current, resistance, and inductance values.

During transient load changes, the rotor can reach a peak stall torque of 1.2 N·m, while the continuous stall torque is 0.20 N·m. A rotor inertia of 0.108 × 10⁻⁴ kg·m² keeps acceleration times short and supports rapid changes in shaft speed. Position data come from an incremental encoder with a resolution of 2000 P/R, enabling fine velocity regulation and accurate homing sequences. The enclosure has an IP43 rating, providing protection against solid objects larger than 1 mm and water sprayed at angles of up to 60 degrees from vertical. This protection is suitable for controlled indoor installations, but the motor should not be exposed to pressure washing or continuous water flow.
