RAC3.5-150-460-A01-W1-220
RAC Spindle Drive Controllers
Rated 4.5 stars (24 total reviews)
The Bosch Rexroth Indramat RAC3.5-150-460-A01-W1-220 from the RAC Spindle Drive Controllers series is a high-precision AC Main Spindle Drive Controller designed for demanding industrial applications. It delivers a continuous controller current of 150 A and a base continuous controller output of 35 kW, with a peak controller output of 40 kW for short bursts of high demand. The controller operates on a rated supply voltage of 3 x AC 380 – 460V, ±10%, 50 – 60 Hz and features a dedicated control voltage of AC 230V, ±10%, 50 – 60 Hz interface. Its rugged design ensures stability and precision for critical spindle-speed regulation tasks.
Engineered for reliability, the unit maintains performance across an ambient temperature range of 5 to 45 °C and conforms to Protection category IP 10 per EN 60 529 standards. Thermal management is handled by an integrated built-in fan that supports consistent heat dissipation under continuous operation. The controller’s regeneration output of 27 kW enables efficient energy recovery during deceleration phases, contributing to lower energy consumption and reduced operational costs. At 49 kg, its robust chassis balances durability with manageable installation and integration into existing drive cabinets.
With its precision analog interface, the RAC3.5-150-460-A01-W1-220 excels in applications requiring meticulous spindle control, such as aerospace and automotive machining. The harmonious integration of high currents, advanced cooling, and energy regeneration makes it an indispensable solution for modern CNC systems. This controller offers industrial engineers a reliable, energy-conscious platform to achieve superior process accuracy and productivity.
