Product Description:
The KDA 3.2-100-3-A00-W1-220 spindle drive is produced by Bosch Rexroth Indramat for the KDA Spindle Drives series. It works as the closed-loop power stage between a DC supply and a machine-tool spindle motor, allowing precise speed and torque control during milling, turning, and grinding processes. In automated equipment, it converts commanded setpoints into regulated motor current so the spindle can accelerate, decelerate, and hold a stable operating speed under varying load. When paired with compatible Indramat power supplies and feedback modules, the unit serves as the controller for a single spindle axis.
This version takes its DC bus from a power supply rated at 300 VDC and can deliver up to 100 A of continuous armature current to the motor windings. A mounted heat sink blower powered by a separate auxiliary line of 220 V/50–60 Hz moves air across the fins to remove transistor and snubber heat during operation. The drive uses forced cooling, so the cabinet must leave enough clearance for the side-mounted fan housing and its airflow path. Command signals enter through a differential ±10 V channel, which means the unit expects an analog speed reference from the CNC or motion controller rather than a digital fieldbus command.
The enclosure operates in ambient temperatures from 5 to 45 °C and retains full current output at elevations up to 1000 m above sea level. For applications that require extra communication channels, this model has no additional interface option, so control connections remain limited to the base configuration. The encoder connector block does not feature an additional input for a secondary feedback device. Because no extra fieldbus or option card is installed, parameter access stays through the standard Indramat interface sockets. Wake Industrial offers a one-year warranty on this product.
