Product Description:
The KDA 3.2-150-3-A0I-W1/S001 spindle drive is manufactured by Bosch Rexroth Indramat as part of the KDA Spindle Drives series. It is identified within that line as design 3 and version 2. In machine-tool cells, the unit energizes and regulates asynchronous or synchronous spindle motors during cutting, grinding, or drilling cycles. The drive is intended for applications where spindle response and steady rotation affect surface finish and process consistency. By converting a fixed DC bus into controlled three-phase output, it supports stable spindle speed during metal-removal operations and other continuous machining tasks.
It draws power from a bus that runs at 300 VDC, and its power section is rated for continuous armature currents up to 150 A, allowing it to energize large-frame spindles without derating. That current capacity suits spindle axes that need sustained torque during heavy cuts or repeated acceleration. Thermal control is maintained by forced cooling using a mounted heat sink blower fixed to the rear panel. Rear-mounted airflow removes heat from the power section without requiring liquid cooling hardware. The blower is supplied from an auxiliary source of 220 V/50–60 Hz, so no separate low-voltage fan circuit is required. Safe operation is specified from 5 to 45 °C when the enclosure climate remains within normal shop conditions.
On the control side, the drive generates an incremental encoder output that mirrors spindle position for downstream CNC controllers, yet it omits a secondary encoder input so only one feedback channel is processed internally. This arrangement fits control systems that rely on the drive for a single spindle feedback path. Velocity demand arrives as an analog speed command, allowing legacy machine controls to interface without fieldbus conversion. This input format suits retrofit installations where the existing control already provides a spindle reference signal. Installation is permitted up to 1000 m above sea level, provided ambient temperature and bus voltage stay within the stated limits.
