    • A structure of the terminals of a brushless motor, which enables the motor to be thin and enables the windings of the motor to be connected to a circuit base board easily and automatically. The brushless motor comprises a rotor section, a stator section, a driving circuit (18), a terminal (6), and a core holder (5). The rotor section has a rotor magnet (7). The stator section has a winding (4) opposed to the rotor magnet (7) in the radial direction of the motor and has a stator core (3) around which the winding (4) is wound. The driving circuit (18) is formed on the surface of a circuit base board (9) electrically connected to the winding (4) wound around the stator core (3). Each terminal (6) has a holder (6b) and a connection part (6c). The holder (6b) holds the winding (4) and is electrically connected to the winding (4). The connection part (6c) is electrically connected to a land part (19) of the driving circuit (18). The core holder (5) holds the terminals (6). The terminals (6) are provided on the surface of the core holder (5), the surface being opposed to the circuit base board (9). At least the holder (6b) and the connection part (6c) are in parallel with the circuit base board (9), and the connection part (6c) is nearer to the circuit base board (9) than the clip-type holder (6b).
    • 无刷电动机的端子的结构能够使电动机变薄并且能够容易且自动地将电动机的绕组连接到电路基板。 无刷电动机包括转子部分,定子部分,驱动电路(18),端子(6)和芯保持器(5)。 转子部分具有转子磁体(7)。 定子部分具有在电机的径向方向上与转子磁体(7)相对的绕组(4),并且具有卷绕绕组(4)的定子芯(3)。 驱动电路(18)形成在电连接到缠绕在定子铁芯(3)上的绕组(4)的电路基板(9)的表面上。 每个端子(6)具有保持器(6b)和连接部分(6c)。 保持器(6b)保持绕组(4)并与绕组(4)电连接。 连接部分(6c)电连接到驱动电路(18)的焊盘部分(19)。 芯架(5)保持端子(6)。 端子(6)设置在芯保持器(5)的表面上,该表面与电路基板(9)相对。 至少保持器(6b)和连接部分(6c)与电路基板(9)平行,并且连接部分(6c)比夹持器(6c)更靠近电路基板(9) 图6b)。
