Product Description:
The KDA 3.2-100-3-LP0-W1 spindle drive is produced by Bosch Rexroth Indramat as part of the KDA Spindle Drives series. It is intended to power and regulate machine-tool spindles, accepting a fixed DC link and generating a controllable three-phase output that follows speed commands from higher-level motion controllers. By integrating dedicated blower cooling and a dual-encoder interface, the unit supports continuous operation while delivering real-time spindle position feedback for precision machining and grinding tasks. The drive is suited for applications where spindle speed must remain stable during changing load conditions, such as cutting, milling, and surface-finishing processes.
The power section is fed from a nominal DC bus of 300 VDC, and its output stage is rated for a continuous phase current of 100 A. Thermal management relies on a mounted heat-sink blower that pushes air directly across the power devices, and it uses forced cooling to keep internal temperatures stable. The blower motor is supplied by an auxiliary line of 220 V/50-60 Hz, allowing the drive to maintain internal airflow even when the main DC link is switched off. This arrangement supports steady thermal performance during long operating cycles and helps the output stage remain within its intended operating range.
Permissible installation conditions include an ambient range of 5 to 45 °C and an elevation up to 1000 m above sea level. Speed reference data enters through a SERCOS interface, while a second encoder input can be assigned to spindle feedback or auxiliary motor feedback for coordinated motion control. This added feedback channel is useful in spindle systems that require synchronized monitoring of more than one rotating element. Within the KDA family, this model is series version 2. The unit should be installed within the stated temperature and elevation limits so it can operate without unnecessary thermal stress.
