Product Description:
Bosch Rexroth manufactures the KDA 3.1-050-3-AQD-W1 a high-performance model in the KDA Spindle Drive series. This drive is suitable to be used in motion control systems where high efficiency is required. It is engineered for precision-driven machine tool operations. It belongs to Drive Series 3 and follows design version 1 standards.
The KDA 3.1-050-3-AQD-W1 Spindle Drive weighs only 17.4 kg and offers hassle-free installation. A blower and a heatsink unit is installed in this model to maintain the drive temperature by dissipation additional heat to the surroundings. The blower operates at a frequency of 50 to 60 Hz and requires a 220 V AC power source. This cooling system confirms continuous operation under extended workloads. A ±10 V analogue input is provided in this model efficient speed control. Also, it has a 1V sinusoidal encoder (auxiliary) to receive exact shaft position of the motor. For motion coordination, the unit features a 16-bit parallel digital auxiliary interface for position commands. The current required by the KDA drive is 50 A along with 300 V of DC bus voltage. It is capable of being mounted up to 1000 MSL. The operating temperature range is from +5 to +55 °C, which meets standard industrial climate requirements. It is ideal for integration into systems demanding efficient and controlled spindle motion.
The KDA 3.1-050-3-AQD-W1 Spindle Drive has a humidity class F which makes it suitable for normal workshop conditions. The protection category is rated IP10, offering internal component protection against solid objects. The KDA 3.1-050-3-AQD-W1 offers reliable performance where speed control, encoder input and forced cooling are critical. All specifications are designed to meet consistent performance and operational safety in automated environments.
