Product Description:

The KDA 3.2-050-3-AQD-W1 sits in Bosch Rexroth Indramat’s KDA Spindle Drives lineup, showing up ready for spindle-driven projects that call for reliable power and a solid overall design. The rated current is 50 A and it runs with DC bus voltage at 300 V, which means steady electricity for demanding jobs, especially in automation settings. This model clocks in at a total weight of 16.6 kg, allowing setups that need sturdy but not oversized drives. Cooling runs on forced air, and there’s built-in support for ambient environments as low as +5°C and as high as +45°C during normal operation, so factories with unpredictable conditions don’t slow it down.

Overcurrent isn’t much of an issue with the KDA 3.2-050-3-AQD-W1, since continuous current can hold at 35 A, making it a smart choice for long-run installations where stopping isn’t an option. The power draw from control supply voltages gets counted too; a +24V system uses 1.2 A, and the ±15V line only calls for 160 mA, both of which fit easily into bigger control panels without needing upgrades. Assembly options get easier due to the mounting kit, and integration works with other Bosch and industrial automation gear. The drive’s protection is handled by an IP10 rating, so basic coverage against hands and larger objects is included.

Transport or storage isn’t tough on this drive either, thanks to a wide range from -30°C to +85°C for non-operating conditions. Weight details cover everything, from the base drive at 16.6 kg to a blower unit that adds 4.2 kg, and the mechanical kit with another 1.7 kg, so real planning for machine design doesn’t get skipped. Spindle and servo applications see a boost in stable current flow with this setup and installation comes quick, whether for upgrades or fresh equipment projects.
