Internal Product Review
The KA511TS0 is a Sanyo Denki K SANMOTION servo motor with 110 W output power and a 3000 min-1 rated speed. A 2000 P/R encoder resolution and 0.35 N·m rated torque give the motor precise feedback and consistent positioning performance. Peak stall torque of 3.4 N·m is a strong advantage for responsive servo applications.

Product Description:
The KA511TS0 is a permanent-magnet servo motor built by Sanyo Denki for the K SANMOTION Servo Motors series. It supplies closed-loop rotary motion for positioning tables, pick-and-place heads, and similar automation axes that require repeatable velocity and torque regulation. When paired with a matching digital drive, the motor responds precisely to command signals while retaining a compact size suitable for equipment with limited installation space.
The windings are designed for an armature supply of 75 V, and continuous operation at this voltage draws a rated phase current of 2.0 A. Under these electrical conditions, the shaft turns at a rated speed of 3000 rpm while producing a rated torque of 0.35 N·m. The motor has an output power capability of 110 W. Speed feedback is delivered through a 2000-pulse-per-revolution incremental encoder, giving the controller fine angular resolution for servo control. The rotor has a low inertia of 0.37 × 10⁻⁴ kg·m², which shortens acceleration time, while a winding inductance of 3.0 mH limits current ripple caused by PWM switching. The motor has a mass of 1.36 kg and transfers generated heat to the mounting surface without requiring forced-air cooling.
Dynamic performance includes a continuous stall torque of 0.42 N·m, allowing the shaft to hold position against static loads without exceeding its continuous thermal limit. A peak stall torque of 3.4 N·m supports brief overloads during rapid indexing. From rest, the rotor reaches 63% of its final speed within a mechanical time constant of 4.5 ms, while current in the armature circuit settles within an electrical time constant of 0.63 ms. The maximum no-load speed is 5000 rpm, providing additional speed range above the rated operating point. A torque constant of 0.20 N·m/A relates armature current to the torque produced by the motor.
