The Bosch Rexroth Indramat KDA 3.3-150-3-D00-W1 is a spindle drive from the KDA Spindle Drives series. It operates with a rated current of 150 Amps and uses forced cooling through a mounted heatsink blower supplied with 220V AC at 50-60Hz. The drive accepts digital speed command values in 16 bit parallel form and is designed for environments up to 1000 meters above sea level within an ambient temperature range of 5 to 45 degrees Celsius.

Product Description:
The KDA 3.3-150-3-D00-W1 belongs to the KDA Spindle Drives series manufactured by Bosch Rexroth Indramat. It is a spindle drive designed to regulate the torque and speed of high-frequency machining spindles in automated production lines. By converting a steady DC link supply into three-phase output, the unit interfaces with Indramat motion controllers to support rapid acceleration, precise overspeed operation, and repeatable positioning during drilling, milling, and grinding tasks. This control approach helps the spindle maintain stable cutting performance as tool load changes during continuous machining cycles.
The power section is energized from a DC bus of 300 VDC, so the drive must share a common supply module with other axis converters on the same rack. Under continuous duty, it can deliver up to 150 A, allowing it to start and decelerate large-diameter spindle motors without thermal derating. Spindle velocity is commanded through a 16-bit parallel digital interface, which provides fine speed resolution for closed-loop CNC systems. An integral heat sink assembly removes switching losses, and its fan receives mains power of 220 V at 50/60 Hz. Because the cooling unit is a mounted heat sink blower, no external ducting is required and cabinet layouts remain compact. This arrangement also keeps the cooling hardware with the drive rather than placing it elsewhere in the cabinet.
The drive operates reliably in ambient temperatures from 5 to 45 °C, and altitude must not exceed 1000 m to maintain full cooling capacity. These limits match the unit’s forced cooling design, which relies on continuous airflow over the power modules rather than passive convection. Wiring remains straightforward because there is no additional interface option, and the second encoder input is omitted so all feedback stays on the primary control channel. That layout keeps the signal path simple and suits standard machining centers that use a single main feedback source for spindle control.
