Product Description:

The RZM01.1-6-030 is a passive line component manufactured by Bosch Rexroth Indramat for the RZM Motor Filters series. As indicated by its product type, the unit functions as a motor filter positioned between a drive controller and a three-phase servo motor in automated installations. By inserting inductive and capacitive elements into the motor lead set, the filter reduces differential noise and helps preserve insulation integrity during high-frequency switching events. Placed at the motor output of the drive, it also helps limit voltage stress on cable runs and motor windings during pulse-width modulation. It also supports stable speed feedback and longer service life in production equipment.

The filter is intended for networks that provide 3 x AC 380–400 V ±15 %, so minor overvoltage or undervoltage on the plant bus does not compromise operation. A continuous capacity of 30 A sets the upper thermal limit for RMS current under standard carrier conditions. With a switching frequency of 4 kHz, the component can still carry that same current level, which shows low series impedance at typical PWM rates. If the drive is set to 8 kHz, the allowable current drops to 25 A to help prevent magnetic core saturation. Under full electrical load, the internal resistive and core losses total 160 W, and that heat must be dissipated through cabinet airflow or supplemental heat sinking.

The module is in Design 1, which uses the enclosure dimensions and terminal orientation of the first generation. As a passive Motor Filter, it introduces no active control logic and instead uses a fixed impedance network to shape the waveform that reaches the motor. This arrangement is suited to multi-axis cabinets where consistent filtering is needed across shared supply layouts. Because the network is passive, operation depends on the connected drive settings, the electrical characteristics of the motor cable, and the switching pattern applied at the inverter output.
