Product Description:

The KA730XS0 is a brushless servo motor manufactured by Sanyo Denki as a member of the K SANMOTION Servo Motors series. In automated assembly stations and material-handling equipment, this motor translates commanded current into tightly regulated shaft motion, supplying both speed control and holding torque without mechanical reduction stages. Its compact build and electrical ratings allow direct connection to modern servo amplifiers, making it suitable for positioning tasks that demand repeatable accuracy and fast cycle times.

At its nominal operating point, the motor produces 300 W while turning at 2500 rpm; this pairing supports a rated torque of 1.15 N·m for continuous motion profiles. When a load must be held without rotation, the winding sustains a continuous stall torque of 1.43 N·m without exceeding thermal limits. Drive electronics deliver 4.8 A of phase current from a 75 V armature bus, and the 1.05 Ω phase resistance helps keep resistive losses moderate during acceleration and deceleration. These electrical values support appropriate inverter sizing and cable selection for reliable closed-loop control.

Dynamic overload capacity reaches 9.8 N·m, allowing short bursts of high torque during indexing or rapid starts. A torque constant of 0.27 N·m/A links commanded current to developed torque, while the armature inductance of 1.7 mH establishes the electrical time constant that the drive must overcome for fast current regulation. The rotor has a moment of inertia of 2.7 × 10⁻⁴ kg·m², supporting quick reversals with minimal overshoot. Feedback is provided by a 2000-pulse line-driver encoder that supplies differential A, B, and Z signals for noise-resistant position tracking. The motor has a 76 mm square flange and a total mass of 3.10 kg, allowing straightforward mounting on compact linear stages.
