In late 2024, a large copper mining operation in South America faced escalating production issues caused by repeated motor failures in its ore-crushing and conveyor systems. The mine operates around the clock under extreme dust, vibration, and heavy load conditions, and its outdated motor fleet was struggling to keep up. Unscheduled downtime had increased by nearly 30%, directly impacting both output and safety.

Seeking a long-term solution, the mine’s engineering team invited wolong nanyang motor to conduct a full equipment evaluation. After inspecting the site, reviewing vibration logs, and analyzing power data from the crushing mills and long-distance conveyors, Wolong specialists concluded that the facility needed a more robust and efficient drive solution. They recommended replacing the old units with the company’s upgraded Three Phase Induction Motor, designed specifically for industrial environments involving high torque and continuous operation.

The first installation took place on a critical primary conveyor line responsible for transporting raw ore from the extraction site to the processing facility. Previously, this line experienced motor overheating and torque instability during peak demand periods. After the Three Phase Induction Motor was installed, operators immediately noticed smoother torque delivery, lower heat buildup, and significantly reduced current spikes. The conveyor began running with consistent reliability, even when handling heavier-than-usual ore loads.

Encouraged by the results, the mine expanded the upgrade to its ore crushers—machines that place intense mechanical stress on any motor. Before the upgrade, the crushers frequently had to be shut down for motor replacement or bearing repairs. Once Wolong Nanyang Motor Three Phase Induction Motors were installed, the maintenance team reported a dramatic reduction in mechanical wear. Motor vibration dropped to stable operating levels, thermal signatures improved, and start-stop cycles became faster and more controlled, allowing for fewer operational delays.

The economic impact soon became undeniable. Within four months, the mining operation recorded a 22% reduction in machine downtime and reported saving hundreds of thousands of dollars in maintenance and emergency repair costs. The improved energy efficiency of the new motors also brought a measurable reduction in overall power consumption—an important advantage given the mine’s remote location and limited grid capacity.
