The stator includes an iron core with a plurality of slots formed therein along a radial direction of the stator. The winding structure has a plurality of hairpin wires with pins disposed in the slots. The winding structure is configured to provide a plurality of phase windings and each phase winding includes a plurality of motor windings. The inverter includes a switching controller configured to control the turning-on and turning-off of the motor windings of each phase winding of the winding structure. When the electric motor operates in a high-speed mode, the switching controller controls the turning-on and turning-off of the motor windings of each phase winding such that a number of the phase windings turned-on is ⅓ less than a number of all the phase windings.

Abstract: A motor stator structure includes a core and plural hairpin wires. The core has slots, an insertion side, and an extension side. Each slot has an innermost layer, a second inner layer, a second outer layer and an outermost layer configured in a radial direction of the core. The hairpin leg protruding from the innermost layer extends for a first span distance, the hairpin leg protruding from the second inner layer extends for a second span distance, the hairpin leg protruding from the second outer layer extends for a third span distance, and the hairpin leg protruding from the outermost layer extends for a fourth span distance. The first span distance is different from the second span distance. The third span distance is different from the fourth span distance. The first and fourth span distances are substantially the same. The second and third span distances are substantially the same.

Abstract: A linear motor includes a case, a magnet assembly and a coil assembly. The case is disposed along a first direction. The magnet assembly includes at least two first magnets, among which the first magnets are disposed corresponding to and between two first magnetic yokes, respectively. The coil assembly includes a winding coil having an exposed portion, among which the exposed portion is extended along a second direction and disposed between the two first magnetic yokes, and the exposed portion is at least partially overlapped with the two first magnets in a third direction. As a result, the coil assembly and the case are driven to reciprocate along the first direction by the winding coil due to the magnetic force, thereby solving the magnetic disturbing issue, enhancing the driving force of the linear motor, and optimizing the mechanical rigidity.
