摘要： An electric motor, especially a brushless PMDC motor, has a stator and a rotor rotatably installed inside of the stator. The stator has a housing with an open end, an end cap fixed to the open end of the housing, a stator core fixed to an inner surface of the housing, and windings wound on the stator core. The rotor includes a plurality of permanent magnetic poles. The housing has a flange bent inwardly from the open end of the housing and abutting against the end cap inwardly and axially to thereby fix the end cap to the housing. The length of the flange measured along the circumferential direction of the housing is greater than half of that of the housing.

摘要： An electric motor includes a stator and a rotor. The stator has a housing and a single ceramic permanent magnet disposed in the housing. The magnet has a C-shaped cross section. During assembly the magnet is resiliently deformed to allow the magnet to be inserted into the housing. The inner diameter of the housing is less than the outer diameter of the magnet in its relaxed state such that once inserted in the housing the magnet is kept resiliently deformed by the housing. The magnet thus generates a radial force acting on the inner surface of the housing which results in the magnet being firmly retained in the housing. A slot is formed between opposing circumferential ends of the magnet. The slot extends from one axial end of the magnet to the other axial end. Preferably, a spacer is pressed into the slot and an interlock structure is arranged between the spacer and the housing to prevent the magnet from moving relative to the housing.
摘要翻译：电动机包括定子和转子。定子具有壳体和布置在壳体中的单个陶瓷永磁体。磁体具有C形横截面。在组装期间，磁体弹性变形以允许磁体插入壳体中。壳体的内径小于松弛状态下的磁体的外径，使得一旦插入壳体中，磁体由壳体保持弹性变形。因此，磁体产生作用在壳体的内表面上的径向力，这导致磁体牢固地保持在壳体中。在磁体的相对的周向端部之间形成槽。槽从磁体的一个轴向端延伸到另一个轴向端。优选地，间隔件被压入槽中，并且互锁结构布置在间隔件和壳体之间以防止磁体相对于壳体移动。

摘要： An electric drill has a handle, a body and a drill chuck. The handle is provided with a battery and a switch. The body comprising a shell, a motor fixed in the shell and an impeller fixed to an axle or shaft of the motor. The shell is provided with a plurality of air outlets at a position corresponding to the impeller, the impeller being able to rotate with the axle of the motor to produce an air current to cool the motor. An enclosure of the battery is provided with a plurality of through holes. An air current channel is formed inside the handle and the body and connected to the environment via the through holes of the battery enclosure. A heat dissipating device is located in the air current channel and contacts the switch. A part of the cooling air current passes through the air current channel to cool the battery before getting to the motor. Thus, a part of the cooling air current can cool the battery and the switch before cooling the motor, so as to prevent the battery and the switch from overheating and shortening their service life.
