Product Description:

The Sanyo Denki KA840BS0 operates to fulfill industrial requirements through precise operations reliable performance and efficient operation. The K SANMOTION Servo Motors series includes this model as a strong solution that meets the requirements for textile processing equipment. The 0.4 kW rated output of the KA840BS0 provides stable operation in the applications requiring medium to high-load conditions. A servo motor produces the 12 N·m stall torque which allows exact control during operations requiring strong forces at reduced speeds. The servo motor reaches a rated speed of 2500 min⁻¹ which supports efficient operation in various industrial applications.

This servo motor features a standard 88 mm flange dimension that makes it convenient for standard industrial mounting applications. The built-in holding brake system from this motor provides maximum security to maintain position stability during idle periods thus allowing it to be effective in critical stability applications. The KA840BS0 shows resistance to industrial operational conditions. The IP43 protection rating makes this motor capable of resisting dust and small water splashes in controlled factory settings.  

Its modular design enables smooth implementation through standard motion controllers and servo drive units which makes this servo motor useful for engineering and machine design applications. The servo motor provides high-performance outcomes when installed in CNC machines for cutting purposes textile machinery for fabric automation and conveyor systems for material handling. The KA840BS0 operates at such low noise levels that it can function properly in environments where sound disturbances should be minimal. This product design supports peak efficiency through its energy-efficient structure which reduces operational expenses. The servo motor serves demanding applications through its reliable performance in manufacturing logistics and material processing applications.
