Plastic-sealed stator assembly and plastic-sealed coil motor

Abstract

The invention is applicable to the field of motors, and discloses a plastic-sealed stator assembly and a plastic-sealed coil motor, wherein the plastic-sealed stator assembly includes a stator assembly, a capacitor arranged outside the stator assembly along the radial direction of the stator assembly, and a capacitor packaged outside the stator assembly and the capacitor plastic casing. In the present invention, the fixed capacitor is directly packaged through the plastic casing, so that, on the one hand, the stable and reliable installation of the capacitor is ensured, thereby ensuring the stable and reliable operation of the motor; on the other hand, the number of components required for capacitor installation is reduced, and the capacitance The material cost of installation is beneficial to realize the automatic installation and production of capacitors, and the production efficiency is high; on the other hand, it eliminates the limitation of capacitors by installation space and realizes the installation of large-volume capacitors. At the same time, since the capacitor is directly packaged in the plastic casing, it minimizes the influence of the capacitor on the radial dimension of the plastic-encapsulated stator assembly, and greatly reduces the problem that cannot be installed due to the large radial dimension of the motor. phenomenon occurs.
