GQ45 STEEL BAR CUTTING MACHINE is a high-performance steel processing machine designed for construction sites, steel fabrication workshops, and infrastructure projects. With its strong cutting ability, stable structure, and efficient operation, it has become a reliable choice for customers worldwide. However, during long-term operation, some users may experience motor overheating and automatic shutdown. Proper troubleshooting and maintenance can quickly solve this problem and ensure continuous production.
Main Causes of Motor Overheating
For the GQ45 STEEL BAR CUTTING MACHINE, motor overheating is usually related to excessive workload, electrical problems, or insufficient maintenance. If the machine continuously cuts steel bars beyond its rated capacity, the motor may operate under heavy load and generate excessive heat.
Other common causes include unstable voltage, loose electrical connections, damaged motor components, poor ventilation, and dust accumulation around the cooling system. In addition, insufficient lubrication of transmission parts can increase mechanical resistance, forcing the motor to consume more power and causing overheating.
Troubleshooting and Effective Solutions
When the motor stops due to overheating, operators should immediately disconnect the power supply and allow the motor to cool. First, check whether the cutting operation is within the recommended capacity range. Then inspect the power supply, electrical wiring, and motor protection system.
Cleaning the ventilation openings, removing dust, checking the cooling fan, and applying proper lubrication to moving components can improve heat dissipation and reduce operating temperature. If the problem continues, professional technicians should inspect the motor winding, bearings, and electrical control system.
