Product Description:
The RZM01.1-5-360 is a motor filter manufactured by Bosch Rexroth Indramat within the RZM Motor Filters series. Installed between a drive converter and an AC motor, it suppresses voltage spikes and common-mode noise, permitting reliable operation of long motor cables in industrial automation cells. By controlling the gradient of inverter output pulses, the filter extends insulation life, minimizes electromagnetic interference, and supports machines that cannot position the drive close to the motor.
Primary electrical limits show how the filter must be integrated. It is specified for a line-side voltage of 3 × AC 500 V ±10 %, matching typical 400 V class inverters that run on elevated bus levels. Power enters through the U1, V1, W1 terminals, flows through the inductive core, and exits on the corresponding motor-side connectors. The assembly can continuously carry up to 360 A, so it pairs with high-current servo or spindle drives used on large gantries. Cable reach is application-dependent: at a modulation frequency of 4 kHz, the permitted length is 200 m, while operating the converter at 8 kHz restricts the run to 120 m. The unit is delivered in Design 1, Line 1 housing and requires no additional cooling interface.
Frequency-related parameters govern the dynamic performance seen by the motor. With the inverter running at the minimum pulse pattern of 4 kHz, the filter limits the fundamental output to 100 Hz. Raising the switching rate to the maximum 8 kHz increases the allowable fundamental to 200 Hz. Internally, it can track carrier frequencies up to 8 kHz without saturation, ensuring the sinusoidal reconstruction remains effective. When shielded cable is used, the manufacturer advises a cable-length derate of 50 % to compensate for higher stray capacitance. Clean separation of power leaves the module through the U2, V2, W2 terminals, completing the drive-to-motor path.
