RAC3.1-150-460-L00-W1-220

The Bosch Rexroth Indramat RAC3.1-150-460-L00-W1-220 drive belongs to the RAC Spindle Drive Controllers series and exemplifies a high-performance AC Main Spindle Drive Controller. It delivers a continuous controller current of 150 A and a continuous controller output of 35 kW, ensuring sustained torque delivery under demanding machining loads. Equipped with an advanced SERCOS interface, it enables real-time, high-speed communication for synchronous multi-axis coordination. The unit's robust design features a Control voltage of AC 230 V, 0%, 500 Hz, offering consistent control power across a wide frequency range.

Featuring a Rated supply voltage of 3 x AC 3800–460 V, 0%, 500 Hz, the controller accommodates global industrial power standards with minimal derating. Thermal management is handled by an integrated Cooling system with a built-in fan, dissipating heat to maintain optimal performance within an Ambient temperature range of 5 to 45 0C. The drive’s Peak controller output of 40 kW supports rapid acceleration and high-inertia loads, while its Regeneration output of 27 kW recaptures braking energy to improve overall system efficiency. Housed in a chassis rated IP 10, it guards against accidental contact and large debris, and its durable frame weighs just 49 kg for streamlined installation.

Integration into existing automation architectures is seamless thanks to the SERCOS interface, which ensures deterministic data exchange and precise spindle positioning. The controller’s fan-cooled design and resilient Protection category deliver reliable operation in dusty or moderate humidity environments. Ideal for main spindle duties in milling, turning, and grinding centers, the RAC3.1-150-460-L00-W1-220 optimizes machine uptime and process repeatability, offering manufacturers a dependable solution for high-precision applications.
