Indramat KDA

Indramat KDA

The KDA 3.2 series is integral to the intelligent digital control systems of Indramat's 2AD asynchronous motors and 1MB frameless spindle motors, offering a consistent power output ranging from 3 to 22 kW at the motor shaft. These drives excel due to their exceptional rigidity, advanced positioning capabilities, and a broad speed range that does not compromise on power delivery. Their robust features make them particularly suitable for spindle drive applications, which include precise spindle positioning and C-axis operations within computer numerical control (CNC) machinery, underscoring their versatility and critical role in sophisticated machining processes.
