KDA 3.3-150-3-DPD-W1

The Bosch Rexroth Indramat KDA 3.3-150-3-DPD-W1 belongs to the robust KDA Spindle Drives series and features a design 3, product KDA platform engineered for high-stiffness spindle applications. This drive delivers a rated current of 150 A and operates on a DC bus voltage of 300 V to ensure continuous power delivery across its extensive speed range. Forced cooling is provided by a dedicated heatsink blower powered via a 220 VAC AC supply source for heatsink blower, maintaining optimal thermal performance. An integrated speed command value Digital 16-Bit Parallel interface and dual feedback capability enable precise control in demanding machining operations.

The KDA 3.3-150-3-DPD-W1 drive incorporates a comprehensive aux. interface Position Command Value Digital 16-Bit Parallel for high-resolution setpoint delivery, while the aux. encoder input with support for spindle or second motor feedback streamlines multi-axis synchronization. The forced cooling by heatsink blower architecture ensures consistent operation at full load, even in elevated ambient temperatures. This spindle drive’s DC bus voltage of 300 V is complemented by its structural rigidity and low-inertia design, delivering rapid acceleration and deceleration for advanced positioning tasks. With a compact footprint and standardized mounting, the unit simplifies integration into existing machine tool platforms.

Designed for precision and durability, the KDA 3.3-150-3-DPD-W1 balances high torque density with fine speed resolution, making it ideal for high-performance milling, grinding, and turning centers. Its modular design and extensive digital command options reduce commissioning time and enable seamless compatibility with Bosch Rexroth control systems. By combining 150 A rated current, 300 V DC bus voltage, and Digital 16-Bit Parallel speed commands, this spindle drive delivers both power and precision for next-generation manufacturing applications.
