电驱动装置

Abstract

本发明涉及一种电驱动装置,具有电机(18)以及用于操控电机(18)的电机控制设备(20),其中,电机(18)具有转子(90)和固定的定子(104),定子(104)具有线圈结构,电机控制设备(20)设计用于向线圈结构通电以产生激励场,线圈结构具有大量线圈股(106),每个线圈股(106)具有大量线圈分段(110、112、114),其中,每个线圈股(106)的大量线圈分段(110、112、114)的至少一个线圈分段(112、114)相对于线圈股(106)的其余线圈分段(110)能够选择性地变换极性。该驱动装置(16)特别适合于应用在电动工具(10)中。
The invention relates to an electrical driver having a motor (18) with a rotor (90) and a stationary stator (104), which has a coil arrangement, and having a motor controller (20) for controlling the motor (18), with the motor controller (20) being configured to pass current through the coil arrangement in order to produce an excitation field, with the coil arrangement having a plurality of coil winding sections (106), and with each coil winding section (106) having a plurality of coil sections (110, 112, 114), wherein the polarity of at least one coil section (112, 114) of the plurality of coil sections (110, 112, 114) of each coil winding section (106) can be selectively reversed with respect to the other coil sections (110) of the coil winding section (106). The driver (16) is particularly suitable for use for an electrical tool (10).
