The Bosch Rexroth Indramat KDA 3.3-150-3-DQS-U1 from the KDA Spindle Drives series is a robust main spindle drive designed for demanding industrial applications. It delivers a Rated Current of 150 A and a DC Bus Voltage of 300 V, ensuring consistent performance across extensive speed ranges. Cooling is provided by a forced heatsink blower powered from a 115 VAC supply, maintaining optimal thermal stability. Control is achieved via a Digital 16-Bit Parallel Speed Command Value, while integration flexibility is enhanced by an Aux. Encoder Input for 1 V sinusoidal encoders and a Serial Interface RS 232 C. The design conforms to series 3 specifications and is engineered for high stiffness, precise positioning, and continuous power delivery.
