Product Description:
The KA506XXX is a brushless servo motor manufactured by Sanyo Denki as part of the K SANMOTION Servo Motors series. Designed for compact axes, it pairs with matched amplifiers to deliver controlled torque and speed for indexing mechanisms, grippers, and light conveyor segments within automated machinery. By converting low-voltage DC power into repeatable rotation, it serves as a core element of precise motion subsystems. Its brushless design supports electronically controlled commutation, allowing the connected amplifier to regulate motion without the mechanical wear associated with brushes.
The motor supplies 60 W of continuous mechanical output while operating at 3000 rpm. This operating point corresponds to a shaft torque of 0.19 N·m and is achieved with a rated armature voltage of 75 V and a rated current of 1.1 A. The copper windings have 4.4 mH of inductance and 9.4 Ω of resistance; these values influence drive tuning, thermal rise, and regenerative behavior. A torque constant of 0.17 N·m/A relates command current to the torque produced by the motor. The back-EMF constant is 17.8×10⁻³ V/min⁻¹, indicating the voltage returned to the controller as rotational speed increases. Under rated conditions, the rotor has a power rate of 1.6 kW/s and can provide 0.24 N·m of continuous stall torque without exceeding its temperature limits.
For transient demands, the motor can reach a peak torque of 1.8 N·m while accepting up to 10 A of phase current. Dynamic response is supported by a rotor inertia of 0.22×10⁻⁴ kg·m², allowing rapid speed changes without excessive overshoot. The mechanical time constant is 7.2 ms, representing the time required for speed to rise from zero to approximately 63 percent of its final value under the stated load condition. The available peak current supports brief acceleration demands that exceed continuous operating levels. Low rotor inertia also helps the drive reverse direction quickly in indexing and positioning applications. Peak operation must remain brief enough to keep winding temperature and magnetic loading within allowable limits.
