Product Description:
The Bosch Rexroth Indramat KDA 3.3-050-3-AP0-U1 is a high-capacity spindle drive from the KDA series designed to manage AC servo motors in automation and precision-controlled operations.
It has a steady current draw of 50 A and can operate on a three-phase supply voltage of 220-240 V AC. The maximum output of supporting power is approximately 11 kW, which is well suited to demanding spindle or main drive applications. The drive's internal bus operates at 300 V DC, which is maintained by the integrated power stage, and its frequency rating is 50/60 Hz. Spindle speed directives are compatible with conventional control signals since they are on a normal analog +/-10 V input. The drive has the standard variety of analog and digital I/O, plus optional auxiliary encoder input to second motor feedback or improved spindle positioning (useful with dual-axis or closed-loop drive systems). Forced external air is a way of cooling through a dedicated blower unit.
The drive can always maintain thermal stability at maximum operating regimes since the fan receives a 220 V AC supply, which actively cools the heatsink. This is necessary in applications that have long duty cycle periods or are subject to high ambient temperatures. It should be placed in a shielded cabinet because it has IP10 protection. Mounting the device on a panel arrangement simplifies deployment and makes it simpler to fit into standard cabinets. It is designed to have a safe operating temperature range of approximately 0°C to +45°C; most controlled manufacturing processes should be able to utilize this device without the need for adding cooling systems. It can be purchased at Wake Industrial with a one-year warranty.
