针对无刷直流电机固定磁瓦的胶黏剂固化时间长的问题，分析计算磁瓦受力获得胶黏剂的最小粘接强度，开发验证热固胶，以实现磁瓦的快速固定。通过高温、低温、高温高湿、冷热冲击、高温及时试验验证了胶黏剂完全固化后的稳定性。结果表明，固定磁瓦所需的最小粘接强度为5.81 MPa，AC451胶水在60 ℃/20 min的条件下粘接强度为15.6 MPa，可实现磁瓦的完全固定。动平衡检测后随平衡泥室温固化5 h，胶水的粘接强度达到22.2 MPa，满足各项型式试验，且安全、可靠，具有广泛的工业应用前景。
Aiming at the problem of long solidification time of adhesive for fixing the magnetic tile of brushless DC motor (BLDCM), the minimum bonding strength of the adhesive is obtained by analyzing and calculating the stress of the magnetic tile, and the rapid fixing of the magnetic tile is realized by developing and verifying the thermosetting adhesive. The stability of adhesive after complete solidification is verified by high temperature test, low temperature test, high temperature and humidity test, thermal shock test, and high temperature timely test. The results show that the minimum bonding strength of fixed magnetic tile is 5.81 MPa, and the bonding strength of AC451 glue is 15.6 MPa at 60 ℃/20 min, confirming that the complete fixation of magnetic tile is realized. After dynamic balance test, the glue solidifies at room temperature for 5 h, and its bonding strength reaches 22.2 MPa, which meets the requiments of all type tests. It is safe and reliable, and has wide industrial application prospects.
