Disadvantages Of Hub Motors
Feb 02, 2023| 1. Although the quality of the vehicle has been greatly reduced, the unsprung quality has been greatly improved, which will have a huge impact on the handling, comfort and suspension reliability of the vehicle.
2. Cost issues. The cost of high conversion efficiency and lightweight four-wheel hub motors remains high.
3. Reliability issues. Putting the precision motor on the hub will cause failures caused by long-term violent up and down vibration and harsh working environment (water, dust). Also consider that the hub part is a part that is easily damaged in a car accident. Maintenance costs are high.
4. The problem of braking heat and energy consumption. The motor itself is heating up. Due to the increase of the unsprung mass, the braking pressure is greater and the heating is also greater. Such concentrated heating requires high braking performance.
