Product Description:

The RZS01.1-6-010 is a passive line component manufactured by Bosch Rexroth Indramat for the RZS Sinusoidal Filters series. As a sinusoidal output filter, it is installed between an inverter and an induction or synchronous motor so the pulse-width-modulated voltage from the drive is reshaped into a near-sinusoidal waveform. This reduces dV/dt stress on motor insulation, lowers conducted electromagnetic interference inside an automation cabinet, and helps limit electrical stress on connected motor windings during inverter operation.

The filter is designed for a three-phase supply of 3 x AC 380 to 400 V, which matches common industrial power systems. A nominal line current of 10 A is the continuous current that can pass through the choke and capacitor network without exceeding thermal limits. Across a usable range of 0 to 200 Hz, the impedance is arranged so that low-frequency fundamental energy passes while high-frequency inverter harmonics are attenuated. The internal LC topology is tuned for a carrier frequency of 8 kHz, which helps suppress the first harmonic peak from typical Rexroth converters. During operation, magnetic and dielectric losses amount to 60 W, and this heat is removed by natural convection inside the control enclosure.

Input voltage may fluctuate by ±15 % without detuning the filter because the component values remain linear across that range. The unit aligns with converter power classes of 1.5 / 3.0 / 4.0 / 5.5 kW, so one filter type can be used with several compatible drive ratings in the same installation. The hardware is delivered as design version 1 and belongs to product line 01. This operating range supports applications such as high-speed spindles or specialized pumps that require elevated motor speed, while still keeping the inverter output waveform smoother than an unfiltered connection.
