Wolong Nanyang Motor explains the main reasons for electric motor overheating in industrial applications. Motor temperature rise affects performance efficiency and service life. Understanding common causes helps improve electric motor operation and avoid equipment failure.

Overload is one of the most frequent reasons for motor overheating. When the electric motor drives a load beyond its rated capacity current increases and winding temperature rises. Continuous overload damages insulation and shortens lifespan. Poor ventilation also leads to overheating. Blocked air ducts broken cooling fans or dusty environments reduce heat dissipation and raise internal temperature.

Voltage imbalance causes uneven current in the windings of a three phase asynchronous motor. This results in excessive heat on one phase and leads to motor overheating. Bearing failure creates friction inside the electric motor increasing surface temperature. Improper lubrication shaft misalignment or worn-out bearings all contribute to thermal issues.

High ambient temperature affects motor cooling especially in enclosed spaces or high-altitude environments. When external temperature exceeds design limits the electric motor cannot release heat efficiently. Repeated start-stop cycles also generate extra heat due to high inrush current.

Wolong Nanyang Motor recommends using energy saving motor designs with optimized ventilation systems and high-grade insulation materials. Motor models are tested for thermal stability under different working conditions. Maintenance schedules should include bearing checks cooling inspections and current balance analysis.

Wolong Nanyang Motor produces electric motors for steel plants cement factories textile lines and mining equipment with reliable thermal performance and long operating life.
