Indramat RAC

Indramat RAC

The RAC Spindle Drive is an advanced drive system designed for high precision and performance in demanding industrial environments. Its robust design allows for a wide range of input voltage options, including 3 x AC 400V at different frequencies, with variations accommodating up to 460V. This adaptability ensures compatibility with a variety of power supply standards across different regions. The RAC series can handle significant load capacities, with type currents available up to 400A, making it suitable for heavy-duty operations.

One of the critical features of the RAC Spindle Drive is its cooling efficiency, achieved through a built-in fan, ensuring optimal operating temperatures and consistent performance. The drive is engineered to deliver continuous and peak power outputs, with models like the RAC 2.2-200 offering 55 kW continuous and peak outputs, and the RAC 2.2-250 going up to 65 kW and 78 kW respectively. Additionally, the series boasts impressive regeneration capabilities, which contribute to energy efficiency by recycling energy back into the system during deceleration phases.
