Product Description:

The Bosch Rexroth Indramat KDA 3.3-050-3-AP0-W1 is a strong spindle engine of the KDA type that works well in advanced manufacturing automation scenarios.

The device can handle medium-to-heavy-duty spindle motor tasks and has an estimated power output of 3.3 kW. It can operate firmly in other difficult systems that require consistent torque and speed control because of its constant output current of 50 A. It has a three-phase input voltage range of 380-460 V, and 50/60 Hz, which is in line with popular industrial power systems. An internal power stage's 300 V DC bus voltage may readily supply energy to a group of linked drive units. Without the need to maintain a liquid cooling infrastructure, the cooling process is maintained through the use of an air-cooled integrated system, which guarantees no issues with maintaining thermal stability in relaying ongoing functions. Flexible motor control and accurate closed-loop control are made possible by the drive's ability to handle encoder and resolver feedback systems.

The KDA 3.3-050-3-AP0-W1 may be integrated with several automation systems since it offers both analog and digital input/output. The common analog speed command input of +/- 10 V allows for a simple connection to older CNC and PLC systems. The unit is an IP20-protected unit mounted in a covered control cabinet to assure protection and keep the unit unharmed by elements outside the case. Supplied with standard panel-mounting fittings, the unit is well-built and of manageable weight (approximately 23 kg), so that it may be integrated into cabinets easily, while not adding substantial bulk to the overall system. It can be purchased at Wake Industrial with a one-year warranty.
