背景技术Background technique
无齿槽电机的电枢铁心由无槽的硅钢片叠成，电枢绕组沿铁心表面借聚酯胶或环氧树脂粘固的电机。此种结构方式可避免由于齿槽存在磁阻不均匀而引起气隙磁感应的脉振，且在直流电机中，可消除电枢铁心中产生脉振损耗和主极极靴表面上产生表面损耗，以利于效率提高。由于消除了槽漏抗，降低了电抗电势，使换向获得改善。对于电动机，则可降低转矩的波动。适用于需要快速动作、功率较大的随动系统中。The armature core of the slotless motor is made of stacked silicon steel sheets without slots, and the armature winding is fixed along the surface of the core by polyester glue or epoxy resin. This structure can avoid the pulse vibration of the air gap magnetic induction caused by the uneven reluctance of the cogging, and in the DC motor, it can eliminate the pulse vibration loss in the armature iron core and the surface loss on the surface of the main pole pole piece. in order to improve efficiency.
