Product Description:

The RZM02.1-6-008 is a passive motor-side filter produced by Bosch Rexroth Indramat as part of the RZM Motor Filters series. It is installed between the drive inverter and the motor leads. In that position, the device suppresses high-frequency switching harmonics and reduces voltage rise times, helping protect motor winding insulation and nearby electronic equipment in automated machinery cells.

The filter accepts a three-phase input of 3-phase 380–400 V AC with a tolerance of ±15%, so it covers the voltage span common to European mains and many dedicated plant supplies. Its maximum continuous conduction path is rated at 8 A, which matches servo or spindle motors that draw similar full-load current. When the inverter operates with a 4 kHz carrier, the unit still handles 8 A at 4 kHz, showing that no additional current reduction is required at that switching speed. At an 8 kHz switching frequency, the permissible line current drops to 6 A at 8 kHz because faster edge transitions increase core and copper losses. Under worst-case thermal loading, the assembly dissipates 140 W, which helps determine the ventilation or heat-sink capacity needed to keep enclosure temperatures within an acceptable range.

The unit uses Design 1, so its mounting holes, terminal orientation, and footprint match other DIN-rail components in the same product line. As a Motor Filter, it is intended for drive regulators that do not have internal sinusoidal filtering and still need better EMI performance on long motor cables. In installations that already use Bosch Rexroth Indramat components, wiring conventions and connector torque values remain consistent, which simplifies integration. The housing dimensions also correspond to other devices in the RZM Motor Filters series, allowing current and switching-frequency requirements to be matched without changing the cabinet layout.
