Product Description:
Bosch Rexroth is a global manufacturer of drive and control technologies. The company provides industrial automation, mobile applications and renewable energy solutions. It delivers precise, efficient and reliable systems for diverse industrial and production applications worldwide. Its products meet high performance and durability requirements.
The KDA 3.2-100-3-DQI-U1 Main Spindle Drive is designed for efficient spindle motor operation. It operates with a DC bus voltage of 300 V. The rated output current is 100 A that allows high load handling. It features an incremental encoder output as the auxiliary interface. The cooling system uses forced cooling for thermal management. An external blower unit model LE4 is integrated for heat dissipation. The blower weighs 4.2 kg and connects to a dedicated heatsink. The AC supply for the blower is 115 V at 50 – 60 Hz. Its forced cooling design ensures consistent performance even during prolonged high load operation. The total drive weight is 17.1 kg. The permissible humidity rating for the drive is Classification F. This allows installation in workshops with cold, moderate or dry warm climates. The average relative humidity must not exceed 70 % in the most humid month. The condensation formation must be avoided.
The KDA 3.2-100-3-DQI-U1 main spindle drive construction supports reliable performance in industrial environments with controlled conditions. The unit accepts a wide range of digital control signals for speed regulation. The ± 15 V measuring voltage capability allows integration with standard feedback and control systems. The design of the model supports high stiffness and wide speed range without loss of torque. The IP 10 rating indicates that the unit should be installed in protected environments to prevent ingress of larger particles.
