一种大中型直流电机用磁轭及其加工方法
摘要：
本发明公开了一种大中型直流电机用磁轭，为柱状壳体结构，所述壳体由弯折的钢板从周向合围并连接构成，本发明装置能够降低生产成本，减小噪音和振动，并且可以在磁轭中通过较强的磁场。本发明还公开了一种大中型直流电机用磁轭的加工方法，首先将钢板加热至500-600℃，用折弯机对整块的钢板进行折弯；再将所述弯折过的钢板从周向合围，并连接在一起。本发明的方法加工步骤简单，生产成本较低。
摘要（英）：

The invention discloses a magnet yoke for a large-middle-sized direct-current motor, and the magnet yoke is a cylindrical shell structure, and the shell is formed by circumferentially encircling and joining a bent steel plate. The magnet yoke can reduce the production cost, noise and vibration, and a strong magnetic field can pass through the magnet yoke. The invention also discloses a machining method of the magnet yoke for the large-middle-sized direct-current motor, and the method comprises following steps of firstly heating the steel plate to 500 to 600 DEG C, and bending the entire steel plate by utilizing a bending machine; and then encircling the bent steel plate from the circumferential direction and joining the bent steel plate. The method is simple in machining steps and low in production cost.
