KA720XS0

Product Description:

The KA720XS0 servo motor is manufactured by Sanyo Denki. It comes with a 76mm square flange, ensuring precise mounting compatibility with standardized mechanical interfaces. This compact footprint is particularly advantageous in applications with stringent spatial constraints, enabling seamless integration into high-density automation systems. The motor delivers a continuous output power of 0.2 kW, signifying its sustained energy conversion capability under nominal operating conditions. This rating is critical for matching the motor’s mechanical workload to system requirements, optimizing efficiency and thermal management. The electrical characteristics are defined by an 80V rated armature voltage, establishing the required power input parameters for stable operation. The 3000 RPM rated speed represents the rotational velocity the motor can maintain under continuous operation, directly influencing its ability to drive loads efficiently. Additionally, the 5000 RPM maximum speed provides an operational buffer, accommodating transient acceleration demands and dynamic motion profiles, which is essential in high-speed automation tasks.

The motor’s torque specifications determine its suitability for various load conditions. Continuous stall torque of 0.77 N·m defines the maximum torque it can sustain indefinitely at zero speed without exceeding thermal limits, ensuring stability in applications requiring constant holding force. The peak stall torque of 5.4 N·m represents the motor’s ability to generate high-torque bursts, crucial for rapid acceleration and handling abrupt load variations. Rotor inertia, measured at 1.47 × 10⁻⁴ kg·m², quantifies the system's resistance to angular acceleration. Lower inertia values facilitate faster response times, reducing lag in dynamic positioning applications. The motor incorporates a 2000 p/r incremental encoder, providing high-resolution feedback for precise position control. This resolution is essential in closed-loop servo applications, where exact positioning and repeatability are paramount. The IP43 ingress protection rating ensures moderate resistance against solid particulates and water exposure, safeguarding performance in industrial settings with controlled environmental exposure.

The output shaft, equipped with a keyway, enhances mechanical coupling reliability by preventing slippage under load variations. The motor features a 1000mm lead wire connection, simplifying electrical integration into automation systems. The absence of a tachometer generator indicates full reliance on the incremental encoder for velocity feedback, a design choice that streamlines signal processing in digital control architectures. With a total weight of 2.1 kg, the motor contributes to overall system inertia considerations, impacting dynamic performance and mounting configurations. These construction details, combined with its compact form factor and advanced feedback capabilities, make the KA720XS0 a robust solution for precision-driven automation, robotics, and motion control applications demanding high responsiveness and reliability.
