Internal Product Review
The KA506TXX is a Sanyo Denki K SANMOTION servo motor with 60 W rated output and 3000 min^-1 rated speed. A 0.19 N·m rated torque paired with 5000 min^-1 max speed supports smooth, responsive motion in compact servo applications. Low rotor inertia of 0.22 x10^-4 kg·m^2 and a 7.2 ms mechanical time constant make this motor especially attractive for fast dynamic performance.

Product Description:
The KA506TXX is a brushless AC servo motor produced by Sanyo Denki within the K SANMOTION Servo Motors series. This compact unit is intended for positioning and speed control in industrial automation, where it couples with a matched drive to supply controlled torque to small actuators and pick-and-place axes. Its 75 V armature winding allows connection to low-voltage servo amplifiers commonly used in laboratory equipment, packaging machinery, and semiconductor handling stages.
The motor delivers a continuous stall torque of 0.24 N·m, allowing it to hold a static load without overheating. Under rated conditions, it turns at 3000 rpm to produce a mechanical output of 60 W while drawing only 1.1 A from the drive. The combination of modest current and a winding inductance of 4.4 mH minimizes ripple and supports stable current loops at high PWM frequencies. Additional electrical values include an armature resistance of 9.4 Ω and a torque constant of 0.17 N·m/A, which determine the voltage needed for commanded torque. An electrical time constant of 0.47 ms supports a rapid current rise, and the rated torque of 0.19 N·m accommodates most light indexing motions.
Dynamic behavior is influenced by a peak operating speed of 5000 rpm for short positioning moves and a rotor inertia of 0.22 × 10⁻⁴ kg·m², which supports quick acceleration with limited overshoot. A mechanical time constant of 7.2 ms complements the motor’s rapid electrical response. The housing weighs 1.00 kg, so mounting it to small gantries or end effectors places little load on supporting structures. A square flange measuring 54 mm per side provides a standard interface for gearheads or couplings. The 75 V winding has a voltage constant of 17.8 × 10⁻³ V per rpm, helping the drive account for back electromotive force during speed regulation.
