A logistics port in Shandong province
Use the low-speed and high-torque permanent magnet motor drive system for the port belt conveyor.
Challenges
1) Frequent start and stop cause high mechanical impact and serious mechanical wear and tear;
2) The belt conveyor using the asynchronous drive is inefficient, some of which has over-matching phenomenon.

Application effect
The low-speed and high-torque permanent magnet motor drive system is tailored according to the operating characteristics of the belt conveyor. With a new electromagnetic program and structural design, the advantages of energy-saving and high efficiency, wide speed range, high overload capacity, non-slippage or backward movement during load startup, capability for precise low-speed operation, easy installation, maintenance-free, and a high cost-performance ratio. It is suitable for various low-speed, high-torque transmission devices. The system is supported by the special inverter for the permanent magnet motor, which has simple operation, stable operation, and convenient speed regulation. Meet the requirements of smart port and carbon peak emission and carbon neutrality.
After this logistics terminal trunk conveyor adopts intelligent permanent magnet direct drive system, the trunk conveyor operates stably, and starts and regulates speed smoothly under various working conditions. The torque meets the requirements, the energy-saving effect is remarkable, and the comprehensive power saving rate can be over 20%.
