    Abstract: An electric machine, such as a brushless direct current motor, includes a number of stator formed as stator sections. The stator sections are longitudinally offset from each other along a common central axis of the electric machine. The stator sections are magnetically independent of one another, but are electrically driven with offset phases typically in a manner similar to a standard multi-phase motor. The stator sections may be further offset with one another in radial position. The structure of the stator sections provides advantages in terms of efficiency, powe consumption, torque, and thermal performance, and can be especially advantageous where a battery is used to power the motor, such as in portable hand tools or driving motors for vehicles.

    Abstract translation: 诸如无刷直流电动机的电机包括定子部分形成的多个定子。 定子部分沿着电机的公共中心轴线彼此纵向偏移。 定子部分彼此磁性地独立,但是通常以类似于标准多相电动机的方式以偏移相电动驱动。 定子部分可以在径向位置上彼此进一步偏移。 定子部分的结构在效率,功率消耗,扭矩和热性能方面提供了优点,并且在电池用于为电动机供电(诸如便携式手动工具或用于车辆的驱动电动机)中是特别有利的。
