What should I do if the motor current is high? ——Cause analysis and solutions
Recently, the discussion on excessive motor current across the network has been very popular, especially in the fields of industrial manufacturing, new energy and home appliance repair. This article combines popular topics and hot contents in the past 10 days to sort out common causes and solutions for motor current abnormalities, and presents key information in the form of structured data.
1. Common reasons for excessive motor current
| Cause classification | Specific performance | Detection method |
|---|---|---|
| Load exception | Mechanical jamming, belt overtight, load overlimit | Manual wheel drive detection resistance |
| Power issues | Voltage imbalance, frequency deviation, harmonic interference | Multimeter measures three-phase voltage |
| Motor failure | Winding short circuit, bearing wear, insulation aging | Megohmmeter detects insulation resistance |
| Environmental factors | High temperature, dust, humidity | Temperature rise test and environmental assessment |
2. Top 5 popular solutions (Data source: Recent Technology Forum Discussion)
