Product Description:
The KDA 3.1-150-3-LPD-U1 spindle drive is manufactured by Bosch Rexroth Indramat as part of the KDA Spindle Drives series. Designed for CNC machining centers, the module mounts inside the electrical cabinet and links the system's DC bus to the spindle motor. By regulating current and monitoring feedback, it helps the numerical control maintain commanded spindle speed during cutting, tapping, and grinding while supporting the fast acceleration and deceleration needed for tool changes and short machining cycles.
The power section accepts a bus voltage of 300 VDC, which the inverter converts into three-phase output for the spindle windings. Continuous output capability of 150 A supports high-torque acceleration without overloading the drive transistors. A dedicated blower circuit supplied with 115 V/50-60 Hz keeps the heat sink within its operating range even when cabinet airflow is limited. Speed setpoints reach the control electronics through the SERCOS interface, and path-accurate contouring data can be superimposed through a digital position command value input. For closed-loop control, the front panel includes a second encoder connection that can accept spindle position feedback or feedback from an auxiliary servo on the same machine.
Heat is removed by a heatsink-mounted blower that forces ambient air through the fin channel, and the overall cooling method is forced cooling. The drive can operate in ambient temperatures from 5 to 45 °C without derating, which matches normal shop-floor cabinet conditions. The maximum installation height is 1000 m above sea level, since thinner air at higher elevations reduces heat transfer and dielectric strength. The control platform also supports bus-based command handling for use with induction or synchronous spindle motors on a common DC link in multi-axis machine layouts.
