Abstract:
A hybrid vehicle is driven by a power unit which includes: a first rotating machine including a first rotor, a first stator, and a second rotor, wherein the number of magnetic poles generated by an armature row of the first stator and one of the first rotor and the second rotor are connected to a drive shaft; a power engine, wherein an output shaft of the power engine is connected to the other of the first rotor and the second rotor; a second rotating machine; and a capacitor. The hybrid vehicle includes: a state detector that detects a charge state of the capacitor; and a controller that controls the power unit. The controller controls the output of the power engine, based on a remaining capacity of the capacitor when driving the power engine in order to start the hybrid vehicle. Accordingly, it is possible to achieve reduction in the size and cost of the power unit and enhance the driving efficiency of the power unit.

Abstract:
An electric motor (M) includes first and second stators (12L, 12R) on the outside forming a rotating magnetic field, an outer rotor (13) disposed inside the first and second stators (12L, 12R) and having first and second induced magnetic poles (38L, 38R), and an inner rotor (14) disposed inside the outer rotor (13) and having first and second permanent magnet (52L, 52R). The phases of the first and second induced magnetic poles (38L, 38R) of the outer rotor (13) are displaced from each other by only half of a predetermined pitch, and the phases of the first and second permanent magnets (52L, 52R) of the inner rotor (14) are displaced from each other by only the predetermined pitch. Accordingly, the first and second stators (12L, 12R) facing the first induced magnetic poles (38L) and the second induced magnetic pole (38R) can be made to have the same phase and polarity, thus simplifying the structures of the first and second stators (12L, 12R).
