Product Description:
Bosch Rexroth Indramat manufactures the KDA 3.2-050-3-A00-W1-220V within the KDA Spindle Drives series. This unit converts the shared DC bus energy of an Indramat supply module into three-phase output for a machine-tool spindle, enabling closed-loop speed control in milling, turning, and grinding centers. By linking the CNC analog velocity channel to the motor phases, it helps maintain spindle speed during load changes and returns regenerated energy to the intermediate circuit. This arrangement lets the spindle respond quickly to command changes from the CNC while remaining suitable for continuous industrial duty.
The drive operates from a DC bus of 300 VDC and can deliver a continuous phase current of 50 A to a connected induction or synchronous motor. A dedicated heat sink blower is supplied by an auxiliary source rated at 220 V / 50–60 Hz, and this airflow passes across the fin stack to limit thermal stress on the IGBT package. The design uses forced cooling to sustain full current at nominal ambient conditions. Speed reference is accepted as an analog command, so the internal regulator converts ±10 V signals from the CNC into torque-producing current with low delay. Because the blower is powered separately, cooling support remains tied to the specified auxiliary supply rather than the motor output stage.
For reliable field installation, the module operates between 5 to 45 °C without derating, and it may be mounted at elevations up to 1000 m above sea level before additional cooling measures are required. System expandability is limited because there is no additional interface option for fieldbus or serial links, and the secondary encoder socket provides no additional input, so feedback duties remain on the primary spindle encoder. This layout keeps the signal path simple and focuses the feedback connection on the main spindle channel. Heat is removed by a mounted heat sink blower fixed to the rear plate, allowing the enclosure to stay sealed inside the electrical cabinet while supporting the stated ambient range. The 3.2 version keeps the established form factor used in Indramat multi-axis racks.
