Product Description:
Sanyo Denki manufactures the KA720BS0 servo motor. The Sanyo Denki KA720JS0 servo motor is designed for industrial automation, and its specs are tailored for optimal performance. The 76mm flange size means it can be mounted in machinery and provides a standard interface. This is key as it allows for compatibility with many mechanical systems. The 0.2kW rating means the power it can deliver. At 3000min⁻¹ rated speed, this is the work it can do in a given time. The 80V rated armature voltage is the electrical potential required for the motor to operate at its designed parameters. This voltage, together with the motor's internal resistance, determines the current flow which directly affects the torque and speed characteristics of the motor. Torque is key for dynamic applications. The continuous stall torque of 0.77N·m is the torque it can sustain indefinitely stationary and is key for maintaining position under load.
Conversely, the peak stall torque of 5.4N·m is the maximum instantaneous torque it can produce and is essential for overcoming inertial loads during acceleration. The rotor inertia of 1.47×10⁻⁴kg·m² and tachometer generator rotor inertia of 0.12×10⁻⁴kg·m² are critical for the motor’s dynamic response. Lower inertia means faster acceleration and deceleration and better response to control signals. The tachometer generator also helps in speed regulation and provides feedback for velocity control. Positioning is crucial in industrial automation and the KA720JS0 achieves this with an incremental encoder with 2000 pulses per revolution (P/R). This encoder provides high-resolution feedback and minimizes positional errors. The 2000 P/R means fine degree of rotational measurement and can track the motor’s angular displacement accurately.
The holding brake adds safety and stability, especially in vertical applications where gravity can cause unwanted movement. This brake provides static holding torque so the load won’t move when the motor is de-energized, thus safe during power outage or maintenance. The output shaft with key allows secure mechanical connection to driven components, prevents slippage, and ensures power transmission. The 1000mm lead wire length provides flexibility in installation and easy connection to control systems. With all these features, the Sanyo Denki KA720JS0 is suitable for applications where precision, efficiency and reliability are key. Its design caters to CNC machines, robots and packaging equipment where accurate motion control is critical. The motor can deliver performance under varying loads and speeds making it a universal component in modern industrial automation.
