    摘要： A motor includes a rotor and a stator having a tubular stator core, first and second electrical insulators arranged on first and second axial ends of the stator care and a stator winding. Each of the first and second electrical insulators includes an outer wall part, inner wall parts and body parts. The stator winding includes first, second and third phase stator windings and each of the windings has winding parts respectively wound around teeth of the stator core, a first lead part and a second lead part. Each of the first lead parts is connected to a power supply, and each of the second lead parts is connected in common to a neutral point part. The outer wall part of the first electrical insulator assembly includes a first movement restriction part that restricts movement of the neutral point part.

    摘要： An electric machine includes a stator having a phase arrangement, and a rotor. The phase arrangement includes first and second legs connected in parallel at first and second primary junctions. The legs each include first and second coils connected in series through a first intermediate junction. The intermediate junctions are connected by a branch such that the phase arrangement is a bridge circuit. The phase arrangement permits an alignment current to flow between the primary junctions via the branch, the alignment current being conducted through an alignment current path passing through one coil of each leg. The phase arrangement includes a negative impedance converter to add a negative electrical impedance to the alignment current path by introducing additional electrical energy into the respective alignment current path. The alignment current causes a translational force to be applied to the rotor for maintaining alignment of the rotor with respect to the stator.
