Product Description:

The RZM01.1-5-054 motor filter is produced by Bosch Rexroth Indramat and belongs to the RZM Motor Filters series. In a drive system, it is installed between the inverter and the machine-mounted servo motor, where it smooths the pulse-width-modulated output and reduces cable-borne voltage spikes and common-mode currents. By limiting these electrical stresses, the filter helps extend motor insulation life and supports electromagnetic compatibility in automated equipment. It is suitable for medium-power motion axes in packaging lines, printing machinery, and general factory automation.

Running conditions are tied to a supply of 3 x AC 500 V with a tolerance of ±10%, allowing correct operation even when plant voltage fluctuates. Its maximum conductor loading is 54 A, which is the highest continuous current the three phases can carry without overheating the magnetic components. At a switching frequency of 4 kHz, the nominal current remains 54 A, whereas at 8 kHz the permissible current drops to 45 A because higher frequencies increase core losses. Internal dissipation is limited to 250 W, so cabinet ventilation must remove that heat to keep the filter within its intended temperature range. This combination suits medium-size asynchronous or synchronous motors used on modular drive platforms.

The product code includes Design 1 and Line 1, which correspond to the mechanical arrangement and electrical layout used for this unit. These codes describe the physical footprint, terminal orientation, and winding arrangement used in this current range. Classified as a motor filter, the unit works with the drive output to reduce dv/dt at the motor terminals and limit common-mode effects on connected cables. This helps protect motor windings while keeping the installation compact inside the control cabinet.
