In this equation, gp denotes a length of a space between adjoining teeth; Pp denotes a central angular pitch of teeth; R denotes a radius of an inner face of a stator; g denotes an interval between the stator and the rotor; t2 denotes a thickness of a magnetic pole circumferential portion; t1 denotes a thickness of a magnetic pole element side portion; n denotes an arbitrary natural number; and x, y, and z are real numbers that satisfy -0.6 ≤ x ≤ 0.6, 0.3 ≤ y ≤ 0.5, and -0.06 ≤ z ≤ -0.04.

摘要： An electrical angle detecting device for detecting the electrical angle of a synchronous motor utilizes differences in inductance between phases with the angle of a rotor 50 to determine electrical angle. Voltage is applied across predetermined phases, the currents Iu, Iv, Iw flowing through U, V, W phases as a function of the differing inductance with angle of the rotor 50 are simultaneously detected, and the electrical angle is determined from relationships among the three currents stored in memory beforehand. In a first stage, the electrical angle is determined in the 0-π range or the π-2π range by an approximation calculation and in a second stage the asymmetry of the maximum currents produced by the voltage applied across the phases is utilized to ascertain the range in which the electrical angle falls. the electrical angle can thus be unambiguously ascertained to enable sensorless detection of rotor position (electrical angle) even when the rotor is at rest or is rotating slowly.

摘要： A power output apparatus of the invention includes a clutch motor (30) and an assist motor (40) that allow energy output from an engine (50) driven at a driving point of high efficiency to be converted to energy expressed as the product of a revolving speed and a torque of a drive shaft (22) and to be output to the drive shaft (22). In case that a large torque is required, for example, when the vehicle starts on a rising slope or runs at a low speed, the engine (50) is driven at a high-energy driving point having a large torque and a high efficiency. This structure causes large electric power to be generated by excess energy greater than the energy generally consumed and enables a battery (94) to be charged with the large electric power. The power output apparatus of the invention further has functions of predicting the process of charging the battery (94) with the large electric power based on a driving state of the vehicle and topographical information and lowering the remaining charge of the battery (94) in advance according to the requirements. This process effectively prevents the battery (94) from being damaged with excess charging.

摘要： In a rotating electric machine incorporating coils (14U-1, 16U-1, 14U-2, 16U-2) having various impedances, the coils are divided into a plurality of groups (14U-1, 16U-1 and 14U-2, 16U-2) so that each of the groups of coils have substantially equal impedances. The groups of coils (14U-1, 16U-1 and 14U-2, 16U-2) are connected in parallel to each other. Therefore, no circulating current occurs even though the coils have different impedances. Hence, the efficiency of the electric motor improves.

摘要： A stator core for a motor in which a member with rounded edges is used to prevent the electrical breakdown of the winding of a coil which may occur at a slot edge therein. End plates 18 are disposed on ends of the stator core 10 formed of laminated magnetic steel plates 12. Each of the end plates 18 has substantially the same pattern as each magnetic steel plate 1, viewed from the axis of the motor. The elongate surface 18a of the end plate 18 continues smoothly from the inner surface 16a of each of slots 16 to the rounded edge surface 18b. The rounded edge surface extends smoothly from the elongate surface 18a to the end surface 18c of the end plate 18. This structure can eliminate sharp edges from the fringe of the slot 16, thus preventing the electrical breakdown of a coated conductor 22 in the coil which may occur at the edges.

摘要： When power is output from an engine 50 to a crankshaft 56, a multiplying gear unit 57 attached to the crankshaft 56 increases a revolving speed but decreases a torque and transmits the increased revolving speed and the decreased torque to a rotating shaft 57e. A drive shaft 22 of a vehicle that cruises at a constant speed is generally driven at a higher revolving speed and a smaller torque than a driving point at which the engine 50 is driven with a high efficiency. The multiplying gear unit 57 converts the power output from the engine 50 to a power of high revolving speed and low torque. This structure decreases the amount of electrical energy transmitted between a clutch motor 30 and an assist motor 40 in the process of torque conversion by the clutch motor 30 and the assist motor 40 and thereby reduces an energy loss of both the motors 30 and 40. This effectively reduces the required capacities and size of the clutch motor 30 and the assist motor 40.
