Toothless traction machine is the core component of mining elevators and a new type of auxiliary lifting equipment that has emerged to adapt to large-scale mining.Its performance directly affects the safety performance and reliable operation of mining elevators.In response to the characteristics of low-speed and large torque of the toothless traction machine for mining elevators and the special requirements for starting,the testing methods related to the load performance of the toothless traction machine were analyzed and studied.A three-level NPC structure inverter was selected as the testing platform,and a load performance test system was constructed to verify the performance of toothless traction machine for 100 kW mining elevator.The results show that the tested toothless traction machine for mining elevator has a stable loading performance and fast response speed.The selected driving unit can smoothly start the toothless traction machine,and the traction machine runs smoothly.The verification results are consistent with the actual situation,which proves that the constructed test system solves the bottleneck problem of mining elevator safety access detection and verification.
