Product Description:
The model KDA 2.1-100-3-LYS-W1 is a main spindle drive designed for integration into industrial systems requiring high performance and reliability. It is suitable for use in controlled environments and supports a variety of motor feedback configurations. The unit is ideal for applications where stable current and controlled heat dissipation are essential for operational consistency.
This KDA 2.1-100-3-LYS-W1 Main Spindle Drive provides a continuous current rating of 70 A and operates within a permissible ambient temperature range of +5 °C to +45 °C. The model is cooled using a heatsink blower system which ensures efficient forced air cooling during continuous operation. The AC supply source for the blower unit is rated at 220 V with a frequency of 50 to 60 Hz. The blower unit itself has a total weight of 4.2 kg while the main spindle drive weighs 17.1 kg. The load voltage consumption at + 24 V is rated at 1.4 A that provides stable auxiliary power support. The drive includes auxiliary encoder inputs that are compatible with AS 35 and synchronous input systems. It is designed to accept speed command values of type A that enables enhanced control of motor response. The protection category of this unit is IP10 which means it is not protected against water or intentional contact by small tools but is suitable for enclosed installations.
The KDA 2.1-100-3-LYS-W1 main spindle drive from Bosch Rexroth must be mounted within a control enclosure or sealed housing in accordance with DIN 40 050 standards to ensure protection against environmental factors such as humidity and condensation. This makes the drive well suited for use in workshops within cold, moderate or dry warm climates, provided relative humidity in the most humid month does not exceed 70 %.
Frequently Asked Questions about KDA 2.1-100-3-LYS-W1:
Q: How does the KDA 2.1-100-3-LYS-W1 handle thermal regulation during extended industrial operation?
