Commercial & Industrial
Common Mode Chokes
Common mode chokes are a vital component in protecting motors, drives, and sensitive electrical equipment from damaging high-frequency currents generated by Variable Frequency Drives (VFDs). These unwanted currents—often referred to as bearing currents—can cause excessive electrical discharge through motor bearings, leading to premature wear, downtime, and costly repairs.
By suppressing electromagnetic interference (EMI) and radio frequency interference (RFI), common mode chokes reduce electrical noise at the source, protecting both motors and connected systems. The result is longer equipment life, reduced maintenance, and improved overall system reliability.
How Common Mode Chokes Improve System Performance
In commercial and industrial environments, electrical systems operate under heavy and variable loads. Without proper filtration, VFD-induced harmonics and high-frequency voltages can impact connected motors, sensors, and control systems. Common mode chokes work by:
- Absorbing high-frequency noise before it travels through power lines or motor windings
- Reducing shaft voltage and bearing current discharge
- Improving motor insulation integrity and reducing heat buildup
- Minimizing interference with control networks and instrumentation
These devices are particularly valuable in HVAC systems, water treatment facilities, manufacturing plants, and data centers, where uninterrupted operation and precise control are essential.

Performance
By suppressing high-frequency bearing currents, common mode chokes help maintain optimal operating conditions for motors and all connected equipment. This leads to smoother operation, reduced electrical noise, and improved power quality throughout the system. In VFD-driven applications, minimizing disruptive currents protects motor bearings and reduces stress on ancillary components such as pumps, fans, and gearboxes. The result is a more stable, efficient, and reliable system that consistently delivers peak performance, even under heavy or fluctuating load conditions.
