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： A brushless direct current motor for use in a HVAC system, has a stator and a rotor rotatably mounted to the stator. The stator has a stator core, field windings wound on the stator core and a bushing. The rotor has a shaft rotatably supported by the bushing and adapted to connect with a valve adjuster of the HVAC system. The rotor also has at least one permanent magnet fixed with respect to the shaft. The bushing is a monolithic construction with two journal portions and one middle portion. The two journal portions support the shaft and are formed at respective axial ends of the middle portion. The middle portion has an inner diameter larger than an outer diameter of the shaft at portions corresponding to the middle portion, so as to form a gap between the middle portion and the shaft.

摘要翻译： 一种用于HVAC系统的无刷直流电动机，具有可旋转地安装在定子上的定子和转子。 定子具有定子芯，缠绕在定子芯上的励磁绕组和衬套。 转子具有由轴套可旋转地支撑并且适于与HVAC系统的阀调节器连接的轴。 转子还具有至少一个相对于轴固定的永磁体。 衬套是具有两个轴颈部分和一个中间部分的整体结构。 两个轴颈部分支撑轴并且形成在中间部分的相应的轴向端部处。 中间部分的内径比对应于中间部分的部分的轴的外径大，从而在中间部分和轴之间形成间隙。
