Product Description:
The model KDA 3.1-150-3-AYD-W1 is engineered for main spindle applications requiring precision and reliability. It provides accurate speed and position control over a wide range. The spindle drive combines high torque capability with precise control for advanced manufacturing systems.
The KDA 3.1-150-3-AYD-W1 Main Spindle Drive integrates analog ± 10 V speed command input. The forced cooling is achieved with a heatsink blower powered from a 220 V AC source. This main spindle drive supports a speed control range starting from 0.0005 rpm that enables accurate C axis operation with a resolution of up to 1/360,000 of a revolution. It ensures excellent spindle positioning for high precision machining processes. The drive delivers a rated current of 150 A with control voltage consumption specified at 1.6 A for + 24 V load voltage and 160 mA for ± 15 V measuring voltage. The unit’s weight is 17.4 kg that ensures robust build quality while maintaining manageable installation requirements. It operates effectively within a permissible ambient temperature range of + 5 C to + 45 C for nominal performance and up to + 55 C with reduced nominal data. The installation of the model is supported up to 1,000 m above sea level.
The KDA 3.1-150-3-AYD-W1 main spindle drive from Bosch Rexroth features auxiliary and synchronous encoder inputs that is compatible with AS 35 interface and speed command value “A.” The protection category of this drive is IP 10 that is only suitable for protected environments where ingress protection against solids and liquids is not critical. The heatsink blower operates from an AC supply of 220 V at 50 – 60 Hz. The high resolution motor feedback or additional spindle feedback options provide enhanced internal position control.
