Clean power is the foundation of effective motor control. At AuCom, line reactors, load reactors, and EMC filters are designed to maintain power-quality, suppress harmonics, and protect sensitive motor control systems under the most demanding industrial conditions.
Line reactors: stabilising supply & protecting infeed systems
Line reactors (sometimes called input reactors) are installed at the supply side of inverters and drives to limit harmonics, reduce voltage spikes, and protect the upstream network. They help maintain compliance with power-quality standards and avoid nuisance trips or failures. Engineers choose AuCom line reactors when the installation involves long motor cables, high switching frequency, or when overlapping loads stress the network.
Load reactors: tough at the output side
Our load reactor models, for example the “Load Reactor AC OUT 1000 3352A” rated at 1000 A input current and designed for 400 VAC inverter systems demonstrate our engineering approach: built with aluminium windings, low inductance, low loss, natural cooling (IP00), and designed for long cable runs and harsh environments. They are specifically used to filter output dv/dt, reduce motor noise, extend motor life and improve overall system reliability under heavy duty. This makes them ideal for applications with long armouring cables, remote motors, or large VFD installations.
EMC filters: ensuring electromagnetic compatibility
When your motor control system interfaces with sensitive electronics, PLCs or drives, EMC filters become essential. They suppress high-frequency interference, protect downstream devices, and ensure uninterrupted operation even in electrical noisy industrial environments. Combined with reactors and drives, EMC filters complete a full motor-control quality solution that meets IEC and EN standards for power quality and electromagnetic compatibility.
Why choose AuCom filters: performance, reliability & integration
- Designed for industrial use: high overload capacity, rugged construction and long service life.
- Engineered to integrate seamlessly with AuCom’s soft starter and variable frequency drives (VFDs), creating a coordinated motor-control ecosystem.
- Global compliance and support: suitable for global installations with consistent documentation, worldwide availability and technical support.
- Improved total cost of ownership: by reducing harmonics, preventing motor degradation and minimizing maintenance downtime, AuCom filters help keep systems efficient and reliable.
Selecting the right filter for your application
- For general power-feed protection and network stabilisation, start with a line reactor.
- For output side motion-control systems with long cables or high switching stress, consider a load reactor, such as the AC OUT series.
- When the environment includes sensitive electronics, variable frequency drives or strict EMC requirements, add an EMC filter to complete the solution.
