Product Description:

The RZS01.1-5-015 sinusoidal filter is produced by Bosch Rexroth Indramat and belongs to the RZS Sinusoidal Filters series. This passive line component sits between a pulse-width-modulated drive inverter and the connected induction motor, smoothing steep voltage edges so the motor windings receive a more sinusoidal waveform. By limiting common-mode voltage and differential voltage gradients, the filter helps reduce motor insulation stress and electromagnetic emissions in industrial automation lines.

The filter is connected to a three-phase supply rated at 3 × AC 500 V, and its terminals remain within the allowed range as long as the input power stays inside the permitted tolerance of ±10 %. Within that range, the inductive network handles line current up to 15 A, allowing it to pair with medium-power converters without thermal overload. It maintains the intended waveform over an output frequency range of 0 to 100 Hz, so drives can run motors from very low speed through base frequency while still benefiting from a cleaner voltage shape. The internal elements are matched to a carrier frequency of 8 kHz, and using the inverter at this switching rate keeps core losses and differential-mode noise within predictable limits for this filter design.

The RZS01.1-5-015 corresponds to converter power classes of 5.5 / 7.5 / 11 kW, aligning its inductance and current capability with the typical continuous ratings of those drives. At full load, it introduces a power loss of only 80 W, so cabinet ventilation requirements remain moderate. The circuit supports an output frequency ceiling of 100 Hz without excessive reactive voltage drop, which can be useful in duty cycles that require overspeed operation. This model is built as design version 1 within product line 01, so it uses the first layout in the series while maintaining the declared electrical ratings.
