Product Description:
The KDA 3.2-050-3-AY0-U1 Main Spindle Drive is designed for use in CNC and automated machining systems. It provides consistent performance and precise spindle control. It is suitable for demanding industrial applications with robust design and high reliability.
The KDA 3.2-050-3-AY0-U1 main spindle drive has a rated current of 50 amperes. It supports an analog speed command input of ± 10 volts that ensures accurate spindle speed adjustments. The unit falls under protection category IP 10 based on DIN 40 050 standards. This offers basic protection against large solid foreign objects but is not protected against liquids or fine dust. The drive integrates a heatsink blower with an AC supply requirement of 115 volts and operates at 50 to 60 Hz frequency. The blower helps maintain temperature during active operation. The spindle drive has a storage and transport temperature range from – 30 °C to + 85 °C which ensures durability under varied environmental conditions during handling and shipping. The drive weighs 16.6 kilograms and its power electronics are built to support high performance spindle control under continuous load. The analog interface makes it compatible with a range of existing CNC configurations and control units. The design of this KDA series drive supports stable operations with consistent current delivery.
This KDA 3.2-050-3-AY0-U1 main spindle drive from Bosch Rexroth is designed for advanced digital control of INDRAMAT’s 2AD series asynchronous motors and 1MB series frameless spindle motors. It provides high dynamic stiffness and precision positioning capabilities. The drive supports a broad and continuous speed range while delivering constant torque output across a wide performance envelope. It ideally suited for demanding tasks such as spindle orientation, synchronized spindle positioning and C axis interpolation in CNC machine tools.
