Abstract (en)
[origin: WO2012119670A1] The invention relates to an electric drive (70), in particular for an electric tool, having a rotor, a stator and a first coil assembly, which is designed to drive the rotor by means of a first rotating field, and having a first motor control assembly (90), which is designed to supply the first coil assembly (86) with electric power in order to generate a first rotating field. The stator has a second coil assembly (88) for generating a second rotating field. The second coil assembly (88) can be driven and energized separately from the first coil assembly (86) in such a way as to drive the second coil assembly (88) with any desired commutation sequence.
