KDA 2.1-100-3-AY0-U1

The Bosch Rexroth Indramat KDA 2.1-100-3-AY0-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat is a high-performance spindle drive designed for demanding industrial applications. With a rated current of 100 A and a DC bus voltage of 300 V, this unit delivers continuous power and torque over a wide speed range. Its primary function is to serve as a reliable main spindle drive, offering high stiffness and precision positioning features for machining centers and automated production lines.

This drive employs a forced air via heatsink blower cooling method to maintain optimal operating temperatures even under heavy loads. The heatsink blower AC supply is set at 115 VAC, ensuring efficient heat dissipation without the need for complex liquid cooling systems. Speed is controlled through an Analog ±10 V speed command input, providing smooth acceleration and deceleration profiles. Auxiliary encoder inputs support both auxiliary and synchronous encoder types, facilitating closed-loop control and enhancing motion accuracy. The product belongs to the KDA-2 product series and features a robust Design 1 housing for reliable protection in industrial environments.

Compatibility is further enhanced by the provision of an auxiliary interface, though in this design version no additional auxiliary interface modules are fitted, allowing for streamlined installation. The forced-air cooling not only extends the service life of internal components but also reduces downtime due to thermal overload. While no formal certifications are listed, the design adheres to industry best practices for electrical insulation and thermal management. In industrial applications, the KDA 2.1-100-3-AY0-U1 spindle drive ensures consistent performance, minimal maintenance, and precise control, making it an ideal choice for CNC machining, milling, and high-speed drilling operations where reliability and efficiency are paramount.
