Product Description:
The KB511XS0 is a compact brushless motor produced by Sanyo Denki for the K SANMOTION Servo Motors series. It functions as the rotary actuator in motion axes that require fast response and repeatable accuracy, such as small assembly robots, indexing tables, and semiconductor handlers. By translating commanded current into proportional torque, the unit provides closed-loop speed and position control for automated machinery. Its DC design pairs with dedicated SANMOTION drives used in distributed control panels, where the motor can receive regulated current commands and return position data to the control system.
At its rated operating point, the motor supplies 0.26 N·m of shaft torque while turning at 3000 rpm, producing 80 W of mechanical power during continuous operation. The armature circuit draws 5.0 A from a 24 V supply, and the 0.44 Ω winding resistance contributes to the heat that must be removed by convection along the frame. A short electrical time constant of 0.61 ms lets phase current rise quickly, improving servo bandwidth during rapid command changes. The motor has a torque constant of 0.06 N·m/A, which provides a proportional relationship between commanded current and output torque. Its back electromotive force has a voltage constant of 6.3 × 10⁻³ V/min⁻¹, supporting consistent speed regulation as the rotor accelerates or responds to changes in load.
The motor can maintain 0.32 N·m of continuous stall torque without exceeding its temperature limit and can reach 2.16 N·m momentarily to accelerate an attached load. A rotor inertia of 0.37 × 10⁻⁴ kg·m² minimizes settling time while helping damp oscillations in lightweight mechanisms. The built-in incremental encoder delivers a resolution of 2000 pulses per revolution, allowing the controller to command fine positional increments and monitor shaft movement accurately. A 54 mm square mounting flange provides the interface for attaching the motor to a machine frame or positioning assembly. The housing has a mass of 1.10 kg, keeping the supported weight low for moving-table and arm-mounted installations.
