Title
(EN) COAXIAL MULTI-MOTOR DRIVE SYSTEM AND VEHICLE PROVIDED WITH SAME
(FR) SYSTÈME D'ENTRAÎNEMENT MULTIMOTEUR COAXIAL ET VÉHICULE POURVU DE CELUI-CI
(ZH) 同轴多电机驱动系统和设置有同轴多电机驱动系统的车辆
Abstract
(EN) A coaxial multi-motor drive system, comprising a shell (111). Two or more sets of motors are arranged in the shell (111), and the motors share a main shaft (101). The motors are permanent magnet synchronous motors, asynchronous motors, or switched reluctance motors, and efficiency diagrams of the motors are different. The drive system can improve the power density and system efficiency of the drive system while maintaining high output performance, strengthens integration, and reduces usage space, weight, and costs of the drive system.
(FR) La présente invention concerne un système d'entraînement multimoteur coaxial comprenant une coque (111). Au moins deux ensembles de moteurs sont disposés dans la coque (111), et les moteurs partagent un arbre principal (101). Les moteurs sont des moteurs synchrones à aimants permanents, des moteurs asynchrones ou des moteurs à réluctance commutée, et des diagrammes d'efficacité des moteurs sont différents. Le système d'entraînement peut améliorer la densité de puissance et l'efficacité du système d'entraînement tout en maintenant une performance de sortie élevée, renforce l'intégration, et réduit l'espace d'utilisation, le poids et les coûts du système d'entraînement.
(ZH) 一种同轴多电机驱动系统,包括壳体(111),壳体(111)中设置有两组以上的电机,电机之间共用一根主轴(101)。电机为永磁同步电机、异步电机或开关磁阻电机,电机的效率图不同。该驱动系统可以在保持高性能输出的同时提高驱动系统的功率密度和系统效率,加强集成化,并减少其使用空间、重量以及成本。
