Internal Product Review
The KA511BS0 is a Sanyo Denki K SANMOTION servo motor with 110 W rated output and 3000 min-1 rated speed. Encoder feedback is well suited for precise motion control, combining line driver output with 2000 P/R resolution. Strong overload capability is a clear advantage, with 0.42 N·m continuous stall torque and 3.4 N·m peak stall torque.

Product Description:
The KA511BS0 servo motor is produced by Sanyo Denki within the K SANMOTION Servo Motors series. As a compact brushless DC unit that integrates an incremental encoder and an electromagnetic brake, it provides closed-loop axis control for pick-and-place heads, small positioning stages, and similar automation axes. By combining modest power output with built-in holding capability, the motor supports steady, repeatable motion in industrial equipment that requires accurate velocity and position regulation.
At its continuous operating point, the motor delivers 110 W of mechanical power while maintaining a shaft speed of 3000 rpm. This performance is achieved with a supply of 75 VDC and a phase current of 2.0 A, which are useful values for sizing amplifiers and cabling. The copper path has an armature resistance of 4.8 Ω, while the winding has an inductance of 3.0 mH. These electrical characteristics limit current rise sufficiently for smooth control while supporting responsive operation across the motor’s intended speed range. The motor provides a peak stall torque of 3.4 N·m, allowing short bursts of torque above the rated torque of 0.35 N·m during acceleration or load disturbances. With a maximum no-load speed of 5000 rpm, the motor can operate in duty cycles that alternate between high-speed travel and precise settling.
For static load conditions, the continuous stall torque reaches 0.42 N·m. A built-in brake rated at 90 VDC and 0.06 A maintains the shaft position when brake power is removed, eliminating the need for external clamps in suitable applications. Feedback is supplied through a line-driver interface with an encoder resolution of 2000 P/R, enabling fine incremental position measurement without additional interpolation electronics. The brake provides a holding torque of 0.29 N·m, allowing appropriately sized vertical loads to remain stationary while the motor is not producing torque. The assembly weighs only 1.46 kg, which reduces moving mass in end-of-arm tooling and other compact mechanisms where weight directly affects acceleration and mechanical wear.
