Product Description:

The KA720TS0 is a permanent-magnet AC servo motor produced by Sanyo Denki and supplied as part of the K SANMOTION Servo Motors series. In positioning tables, semiconductor tools, or pick-and-place axes, this motor converts commanded current from a matching drive into controlled angular displacement, delivering closed-loop velocity and torque for precise automated motion. Its square 76 mm frame integrates easily into compact mechanical envelopes, and the built-in incremental encoder reports rotor position to the controller so that interpolation, synchronization, and rapid settling can be achieved in industrial automation systems.

During continuous operation, the motor delivers a 200 W mechanical output while turning at a rated speed of 3000 rpm. At that operating point, it produces a steady shaft torque of 0.64 N·m from a phase current of 3.4 A supplied at an armature voltage of 80 V. The 3.3 mH armature inductance filters the drive’s pulse-width modulation switching so current ripple remains low, and a 2.2 Ω copper resistance establishes the I²R loss that must be removed through conduction by the aluminum housing.

For transient moves, the drive can command up to 5.4 N·m of peak stall torque, providing short bursts of force that overcome static friction or seat mechanical couplings. Continuous stall torque is limited to 0.77 N·m, a value that is relevant when sizing holding brakes or evaluating vertical loads. Dynamic response is supported by a rotor inertia of 1.47 × 10⁻⁴ kg·m², so the motor follows position commands with minimal lag even when coupled to low-mass mechanisms. Feedback accuracy comes from the integrated incremental encoder, which provides a resolution of 2000 P/R and supports tight servo-loop gains for contouring, electronic gearing, and coordinated multi-axis interpolation across a range of automated machinery.
