How to Reduce Electromagnetic Interference in Three-Phase Motors
Shielded cable, optimization of wiring, use of filters, and good grounding hold the key to the reduction in EMI in three-phase motors. Double-shielded cables can reduce high-frequency interference by 50-70%, the grounding resistance should be controlled below 1 ohm, and the grounding wire length should not be more than 1 meter. On the power side, […]
What factors should you consider when installing a three-phase motor
When installing a three-phase motor, the motor’s power must match the load it will be driving. Running a 15kW-rated motor at 50-70% load will avoid overloading that may eventually lead to failures. Wiring, power supply voltage, and good ventilation must also be considered to prolong the motor’s lifespan. The power supply should be sufficient and […]
