The invention discloses a forcibly-driven inner rotor permanent magnet synchronous traction machine, relates to the technical field of traction machines, and aims to solve the problem that the spatial layout of an existing forcibly-driven motor is not compact enough. A winding stator iron core and an output shaft are arranged in the motor shell, and the output shaft is fixedly connected with the winding drum; a rotor magnet yoke is fixed to the portion, located in the motor shell, of the output shaft, a permanent magnet is arranged on the inner side of the rotor magnet yoke, and a flat key is arranged on one side of the permanent magnet. A rear support and a front support are fixed to the two ends of the winding drum respectively, and a brake is installed at the end of the front support. The winding iron core, the permanent magnet, the rotor magnet yoke and the machine shell are built in and hidden in the winding drum, the space occupied by the driving main body is reduced, the motor structure is more compact, the driving main body is covered by the winding drum in the running process of a main engine, and the risk that the driving main body is collided by foreign objects is reduced.

    本发明公开了一种强制驱动的内转子永磁同步曳引机,涉及曳引机技术领域,旨在解决现有的强驱电机空间布局存在不够紧凑的问题,其技术方案要点是:包括卷筒,卷筒的内部安装有电机机壳,电机机壳的内部装设有绕组定子铁芯和输出轴,且输出轴与卷筒固定连接;输出轴位于电机机壳内的部分固定有转子磁轭,转子磁轭的内侧装设有永磁体,永磁体一侧装设有平键;卷筒的两端分别固定有后支座和前支座,前支座的端部安装有制动器。本发明通过将绕组铁芯、永磁体和转子磁轭、机壳这些结构内置隐藏至卷筒内部,减少驱动主体对空间占用,使电机结构更加紧凑,在主机运行过程中,驱动主体被卷筒覆盖在内侧,减少被外物碰撞的风险。
