Product Description:
The KDA 3.2-100-3-DQD-U1 Main Spindle Drive is ideal for spindle positioning and C axis operations in CNC machine tools. Its compatibility with Rexroth Indramat spindle and asynchronous motors ensures seamless integration into existing CNC systems.
The KDA 3.2-100-3-DQD-U1 Main Spindle Drive ensures stable performance and precise positioning functions. This drive has a weight of 17.1 kg and uses a forced cooling system to maintain optimal performance during extended operation. It supports a continuous current of 70 A and has a permissible maximum ambient temperature of + 55 °C when operated at reduced data. The measuring voltage of the model is ± 15 V with a maximum of 160 mA output. It uses a digital 16 bit parallel speed command value input for precise control. The model is well engineered thermal management system that ensures safe operation even at high workloads. The drive is equipped with a heatsink blower designed for thermal management of the power electronics. The blower is powered by a 115 V AC supply and is rated to operate within a frequency range of 50 to 60 Hz. The blower unit (LE4) itself has a weight of 4.2 kg that aids in effective heat dissipation.
The storage and transport temperature tolerance for the KDA 3.2-100-3-DQD-U1 main spindle drive ranges from -30 °C to +85 °C. This ensures durability under varying environmental conditions. The drive’s robust build and accurate control capabilities make it reliable for continuous spindle operation under demanding industrial settings. The spindle drive is classified with a protection rating of IP10. This indicates that the enclosure provides protection against accidental contact with large solid objects but does not offer protection against the ingress of water.
