    • An electric motor stator including a yoke having a plurality of yoke laminations. A body portion is formed as part of each of the plurality of yoke laminations. A first tooth is continuous with the body portion and is formed as part of at least a portion of the plurality of yoke laminations. The first tooth defines a first tooth profile. A first tooth attachment portion is formed as part of the plurality of yoke laminations. A second tooth includes a plurality of tooth laminations. Each tooth lamination of the second tooth includes a second tooth attachment portion and defines a second tooth profile that differs from the first tooth profile. The second tooth attachment portion is engaged with the first tooth attachment portion.

    • An electric machine having a stator assembly that includes a stator core and a coil supported by the stator core and a rotor assembly that includes a shaft and a rotor supported by the shaft that is in magnetic interaction with the stator core. The electric machine may include a single sensor configured to detect magnetic polarities of the rotor as the rotor rotates relative to the sensor and to generate a signal representing the detected magnetic polarities of the rotor. The signal and an inverted version of the signal are utilized to control current through the coil. The current may be controlled indirectly by controlling the application of voltage to the coil. The sensor may be encapsulated on a circuit board to positively position the sensor relative to the circuit board. The circuit board may be mounted to a bearing housing of the electric machine. The sensor may be received in a pocket of a bearing housing of the electric machine so the sensor is positively positioned relative to the rotor. The rotor may be connected to the shaft with an encapsulation material. The rotor may be formed as a single cylinder of ferrite. A tapered air gap may be formed between a portion of the stator core and a corresponding portion of the rotor. The electric machine may be a C-frame electric motor with the I-bar portion formed of grain-oriented electric steel.
    • 一种具有定子组件的电机,该定子组件包括定子芯和由该定子铁芯支撑的线圈,以及一转子组件,该转子组件包括轴和由轴支撑的转子,该转子与该定子铁心磁相互作用。 电机可以包括单个传感器,其构造成当转子相对于传感器旋转时检测转子的磁极性,并产生表示所检测的转子磁极性的信号。 信号的信号和反相形式被用于控制通过线圈的电流。 可以通过控制对线圈施加电压来间接地控制电流。 传感器可以封装在电路板上,以使传感器相对于电路板正确定位。 电路板可以安装在电机的轴承座上。 传感器可以被接收在电机的轴承壳体的凹槽中,使得传感器相对于转子被正确地定位。 转子可以用封装材料连接到轴上。 转子可以形成为单个铁素体圆柱体。 可以在定子铁芯的一部分和转子的对应部分之间形成锥形气隙。 该电动机可以是C形电动机,其中I形杆部分由晶粒取向的电钢形成。
