Product Description:
The KB511BS0 is a brushless servo motor supplied by Sanyo Denki within the K SANMOTION Servo Motors series. Its compact 54 mm square flange and overall mass of 1.46 kg allow it to fit into small axis assemblies on pick-and-place modules, indexing tables, and light conveyors. In an automation cell, the motor provides closed-loop rotary motion for loads that require accurate positioning and controlled speed. An integral line-driver encoder returns motion data to the controller, while a fail-safe brake secures the shaft when power is removed. This arrangement is suitable for equipment with vertical or suspended loads that must remain stationary during a power interruption.
The motor has a rated mechanical output of 80 W. At its rated speed of 3000 rpm, the shaft delivers a continuous torque of 0.26 N·m. Rated current is 5.0 A when the motor operates from a regulated 24 V DC bus. Motion feedback is generated by an incremental encoder with a resolution of 2000 P/R. Its differential line-driver circuit transmits the encoder pulses over twisted-pair leads, helping the feedback signal resist electrical noise in industrial machinery. The available output, speed, and continuous torque support low-inertia axes that require stable velocity regulation during repetitive operating cycles.
The armature has an inductance of 0.3 mH and a winding resistance of 0.44 Ω. These electrical values affect current rise time and copper loss during acceleration, deceleration, and torque reversal. For short operating intervals, the motor can produce a peak stall torque of 2.16 N·m. The rotor inertia is 0.37 × 10⁻⁴ kg·m², which supports responsive motion and helps limit overshoot at the end of high-speed moves. The integrated brake provides 0.29 N·m of holding torque when power is removed, preventing the shaft from drifting under a stationary load. During normal powered operation, the 90 VDC brake coil releases the shaft so the motor can rotate freely. Compact gearheads or direct-drive couplings can be attached without placing excessive mass on small machine frames.
