Product Description:

The KA506BS0 is a compact DC servo motor produced by Sanyo Denki within the K SANMOTION Servo Motors series. It provides closed-loop rotary actuation for positioning tables, small pick-and-place heads, and other precision axes where repeatable speed and torque are required. By combining a low-voltage armature with an integrated incremental encoder, the unit provides feedback that allows motion controllers to correct errors in real time and keep tooling synchronized with the commanded motion profile.

The motor is rated for a continuous mechanical output of 60 W, which is the amount of shaft power it can deliver without thermal derating. When supplied with the nominal armature voltage of 75 V and a steady armature current of 1.1 A, the shaft reaches its rated speed of 3000 rpm while producing a continuous torque of 0.19 N·m. An armature resistance of 9.4 Ω limits current during startup, while an armature inductance of 4.4 mH filters commutation ripple. The brake resistance is 1600 Ω, allowing an external dynamic braking module to dissipate regenerated energy when rapid deceleration is required. The motor weighs 1.16 kg, which limits the load on its mounting surface while providing sufficient housing mass for heat conduction.

The motor has a torque constant of 0.17 N·m/A, allowing the controller to translate a requested torque into a corresponding current setpoint. For static holding or emergency stopping, the embedded brake supplies 0.29 N·m of holding torque. The rotor inertia is 0.22 × 10⁻⁴ kg·m², supporting rapid acceleration and deceleration in positioning applications. Position feedback is generated by a three-channel incremental encoder with a resolution of 2000 P/R. Its line-driver output circuit provides differential signaling that resists electrical noise between the encoder and the connected drive. The three feedback channels support directional counting and reference-position detection, enabling accurate tracking of shaft movement during closed-loop operation.
