Product Description:
The KDA 3.2-050-3-AYD-W1 Main Spindle Drive is engineered by Bosch for reliable spindle motor control in industrial environments. This main spindle drive is purpose built for steady operation in CNC controlled systems.
The KDA 3.2-050-3-AYD-W1 main spindle drive supports a DC bus voltage of 300 V and utilizes an analog ± 10 V speed command signal for accurate speed regulation. This unit is designed for installation at elevations up to 1000 meters above sea level and adheres to humidity category F under DIN 40 040 standards. The drive integrates a mechanical mounting kit (M1-KD) weighing 1.7 kg which ensures secure installation. It supports a measuring voltage of ± 15 V with a current draw of 160 mA. The analog ± 10 V speed command allows seamless integration with various CNC and automation systems. The unit's power electronics are optimized for performance in demanding spindle applications where accurate speed control and response time are essential. Its design accommodates compact integration into control cabinets or motor enclosures. It is designed for horizontal mounting within the machine system. The unit's high tolerance to extreme storage temperatures (–30°C to +85°C) also supports long term stocking in varied climates without risk of degradation.
The KDA 3.2-050-3-AYD-W1 main spindle drive from KDA series is ideal for retrofits and replacements in legacy systems. The IP 10 protection means the unit should be housed in a controlled environment such as an electrical cabinet. The 220 V blower unit actively cools the heatsink. The drive supports high torque applications particularly in large scale machining tasks with its 50 A rating. Its 16.6 kg weight ensures physical stability once installed. This model ensures the spindle responds accurately to speed variation commands.
