Product Description:
The model KDA 3.1-150-3-L0S-U1 is a main spindle drive built for robust industrial use. It supports continuous operation in workshops and controlled environments. The unit operates with forced cooling and ensures reliable power delivery. It provides stable spindle control with essential safety features.
The KDA 3.1-150-3-L0S-U1 Main Spindle Drive operates with a rated current of 120 A. Its cooling mode is forced cooling that ensures effective thermal management under continuous load. The control voltage bus of the drive requires +24 V with a current consumption of 1.2 A. The blower supply is rated at 115 V that supports efficient airflow for cooling. This main spindle drive has a protection category of IP10. This rating provides protection against accidental contact with large solid objects exceeding 50 mm such as a hand or large tool. However, the enclosure offers no protection against smaller solid particles, dust ingress or any form of liquid exposure. Additional environmental safeguards must be necessary when operating in dusty or humid industrial conditions such as storing the unit in a control cabinet with adequate protection (minimum of IP54 protection rating). The maximum ambient temperature with derating is + 55 °C. The care must be taken to avoid condensation. The drive provides dependable performance while meeting required safety standards.
The KDA 3.1-150-3-L0S-U1 main spindle drive from Bosch includes an auxiliary output through a serial RS232C interface that supports communication and diagnostics. This ensures safety and long term operational stability. The drive has been designed to work within industrial automation environments requiring precise spindle control. It supports compatibility with other system components for integrated control functions. Its compact design reduces space requirements in control cabinets.
