Product Description:
The KA511XS0 is a brushless servo motor manufactured by Sanyo Denki for the K SANMOTION Servo Motors series. Its 54 mm square flange fits compact mechanical frames, while the motor provides precise rotary positioning for automated pick-and-place arms, small conveyors, and indexing tables. In these systems, it converts regulated electrical power from a compatible servo drive into controlled torque. The integrated incremental encoder returns position data to the controller, allowing the drive to correct motion as operating loads change.
The motor operates with an armature voltage of 75 V and an armature current of 2.0 A. These electrical values establish the operating point and associated heat generation that the installation must accommodate. The shaft has a rated speed of 3000 rpm and produces a rated torque of 0.35 N·m, providing continuous mechanical output for connected gearboxes and loads. A torque constant of 0.20 N·m/A allows the controller to adjust output torque through corresponding changes in motor current. For feedback, a line-driver encoder generates 2000 pulses per revolution as square-wave signals. Its differential signaling helps preserve feedback integrity in electrically noisy machinery and supports accurate position and speed regulation by a digital motion controller.
The rotor can accelerate to a maximum speed of 5000 rpm, providing additional speed range for rapid indexing movements. During short transients, the motor can withstand a peak stall torque of 3.4 N·m, allowing it to accommodate brief overloads or demanding acceleration cycles. Its continuous stall torque is 0.42 N·m, which supports applications that require torque while the shaft is stationary. A rotor inertia of 0.37 × 10⁻⁴ kg·m² allows the motor to respond quickly to changing motion commands and reduces the effort needed to accelerate or decelerate the rotor. The motor has a mass of 1.10 kg, limiting the additional weight placed on mounting brackets, moving carriages, and compact machine structures. This low mass is especially useful when the motor itself travels as part of a gantry or positioning assembly.
