Product Description:
The KA730BXX servo motor is produced by Sanyo Denki within the K SANMOTION Servo Motors series. Intended for precision positioning in industrial automation, it converts drive commands into controlled rotary motion for compact axes. The motor attaches through a 76 mm square mounting flange, and its overall length of 162.5 ± 2 mm lets it fit shallow machine frames while still accommodating an internal electromagnetic brake assembly. These dimensions make the unit suitable for use in pick-and-place gantries, labeling heads, and small conveyor sections.
Under nominal load, the motor delivers a continuous mechanical output of 300 W. This output is achieved when the armature is supplied with 75 V and the winding draws 4.8 A. At that operating point, the shaft rotates at 2500 rpm and produces 1.15 N·m of torque, giving it a speed-torque profile suited to light conveying, indexing tables, and similar duties. The interaction between the windings and permanent magnets produces a torque constant of 0.27 N·m/A, so each additional ampere from the drive increases torque by approximately one-quarter of a newton-meter. These values provide the electrical and mechanical data needed to select a compatible power supply and drive while accounting for expected thermal and dynamic loads.
For static holding, the integrated brake supplies a torque of 1.47 N·m. The brake coil operates at 90 V ± 10% and draws 0.11 A through a resistance of 820 Ω, allowing it to connect to a compatible brake controller without excessive heat buildup. Rapid acceleration is supported by a low rotor inertia of 2.7 × 10⁻⁴ kg·m², while the total mass of 3.09 kg reduces the load added to moving carriages. The enclosure has an IP43 rating, protecting internal components against solid objects larger than 1 mm and water sprayed at angles of up to 60 degrees from vertical. This level of protection is appropriate for installation inside factory equipment where the motor is not exposed to heavy dust or direct washdown.
