Compare Effective Solutions for Reducing Common Mode Noise.
When it comes to ensuring the longevity and reliability of your motors, especially in systems using variable frequency drives (VFDs), having the right protective equipment in place is critical. Below, we highlight four key solutions designed to safeguard your motors from electrical damage and enhance their overall performance.
Shaft Grounding Rings
Protecting Motor Bearings from Electrical Damage
Purpose: Shaft Grounding Rings prevent motor bearing damage caused by harmful electrical discharges from VFDs.
How It Works: Conductive microfibers encircle the motor shaft, grounding stray voltage and preventing it from damaging the bearings.
Key Benefits:
- Low Maintenance: After installation, there’s typically no need for ongoing upkeep.
- Adaptable: Performs reliably in varying environments, from humid to extreme temperatures.
- Durable: Designed for longevity, these rings last over 200,000 hours with minimal wear.
- Reliable: Complete shaft contact ensures superior motor protection.
Inductive Absorbers
Suppressing High-Frequency Noise for Motor Protection
Purpose: Inductive absorbers suppress high-frequency electrical noise from VFDs, shielding motor bearings and components from potential damage.
How It Works: Nanocrystalline rings placed on VFD lead wires absorb damaging electrical noise before it reaches the motor.
Key Benefits:
- Increased Reliability: Reduces motor wear by blocking harmful high-frequency noise.
- Time-Saving Installation: Typically installs in under 10 minutes.
- Cost-Effective: Requires no maintenance, lowering long-term costs.
- Advanced Technology: Absorbs noise rather than redirecting it like traditional grounding solutions.
MTE dV Sentry® Filter
Comprehensive Motor Protection from Voltage Spikes and Currents
Purpose: dV Sentry provides full motor protection from voltage spikes and common mode currents, improving motor life.
How It Works: This filter reduces peak voltage, rise time, and common mode currents on the motor’s load side, offering a compact and quiet solution.
Key Benefits:
- Advanced Protection: Reduces voltage, rise time, and common mode currents in one unit.
- Compact Design: Small footprint and easy installation.
- Quiet Operation: Operates quietly, comparable to normal conversation levels.
- Low Heat Generation: Minimizes energy loss, reducing the risk of motor overheating.
MTE SineWave Nexus® Filter
Complete Motor Protection with Combined Sinewave and Common Mode Filtering
Purpose: SineWave Nexus cleans the waveform from VFDs and eliminates damaging common mode voltage, offering total motor protection.
How It Works: This filter combines sinewave and common mode protection in a single device, ensuring motor bearings are safe from harmful electrical currents.
Key Benefits:
- Comprehensive Solution: Provides both differential and common mode protection, eliminating the need for additional devices.
- Longevity: Increases motor life by reducing overheating, insulation stress, and bearing damage.
- All-In-One Design: Simplifies installation and cuts costs by replacing multiple components.
Understanding these essential motor protection solutions enables you to make informed decisions about what’s best for your system.
