Product Description:
Sanyo Denki manufactures the KA511BS0 servo motor. Compact design with 54mm flange size for easy integration into various industrial environments. This physical size determines the motor’s mounting and overall footprint in a system. Functionally, the motor has a rated output of 0.11kW, which is the power it can continuously supply. This is a key metric that defines the motor’s ability to handle mechanical loads and drive various automation tasks. The rated armature voltage of 75V is the operational electrical range of the motor and impacts the power supply compatibility. The rated speed of 3000 min⁻¹ is the speed the motor operates under its rated load, which is critical for applications that require specific motion profiles. It can also reach a maximum speed of 5000 min⁻¹, which is the upper limit of its dynamic performance for high-speed applications.
The motor’s torque characteristics are key to its load handling. The continuous stall torque of 0.42 N·m is the steady state torque the motor can maintain when stationary, which is important for applications that require holding force. The peak stall torque of 3.4 N·m is the maximum instantaneous torque the motor can produce, which is critical for overcoming initial inertia and handling transient loads. The rotor inertia of 0.37 × 10⁻⁴ kg·m² is the motor’s resistance to changes in rotational speed, which impacts its responsiveness and acceleration/deceleration performance. The encoder is an incremental encoder with a resolution of 2000 p/r, which provides precise positional feedback to enable accurate motion control. This resolution determines the position measurement granularity and directly impacts the servo system’s precision. There is no tachometer generator, so speed feedback is derived from the encoder. There is a holding brake to ensure positional retention when the motor is de-energized, which is important for safety and load stability.
The motor’s environmental ruggedness is rated IP43. This means protection against solid objects larger than 1mm and water spray at 60° angles, which makes it suitable for industrial environments with moderate dust and moisture. The motor weighs 1.46 kg, which is a design consideration for the overall weight and dynamics of the machine. The output shaft with a key provides a standard mechanical interface to connect to driven components. The lead wire connection makes electrical integration easy. There is no oil seal, so it’s not recommended for heavy fluid exposure applications.
