摘要： A rotor core has permanent magnets. Magnetic flux of the permanent magnet of an even-numbered rotor magnetic pole part is guided in an axial direction by an axial magnetic path member. Magnetic flux of the permanent magnet of an odd-numbered rotor magnetic pole part is guided into a soft magnetic inner cylindrical part. The axial end faces of the inner cylindrical part and the axial magnetic path member protrude from the rotor core in the axial direction and face a stationary magnetic path member with a small gap therebetween. The amount of magnetic flux of the magnet, which the permanent magnet applies to a stator core is adjusted by an excitation current of an excitation coil wound on the stationary magnetic path member.

摘要： The invention relates to an electric machine, in particular to a generator for supplying the electrical system of a motor vehicle, comprising a laminated rotor (20) with an energiser winding (29), which provides the energisation for the machine preferably in conjunction with permanent magnets (24, 25) arranged on the rotor periphery. According to the invention, the rotor laminate bundle (21) is made up of at least two part bundles (21a, b) in the axial direction with grooves (40) running into each other and with poles offset relative to each other (32 to 38). A machine with reduced detent torque is thus obtained with grooves (40) aligned parallel to the axis, in which the energiser windings (29) can be placed with a high filling factor and without production difficulties and without the risk of damaging the winding insulation.

摘要： A rotor for an automotive alternator includes a rotary shaft, first and second magnetic pole cores each having a plurality of magnetic pole claws, a bobbin, a field coil, a plurality of permanent magnets, and a positioning mechanism. The magnetic pole claws of the first magnetic pole core are interleaved with those of the second magnetic pole core. The field coil is wound around the first and second magnetic pole cores via the bobbin. The permanent magnets are interposed between the first and second magnetic pole cores. The positioning mechanism, which is made up of at least one of the rotary shaft, the first and second magnetic pole cores, and the bobbin, functions to position the first and second magnetic pole cores in the circumferential direction of the rotary shaft with intervals between adjacent pairs of the magnetic pole claws of the first and second magnetic pole cores being even.

摘要： An electric motor (10) has a field pole formed by a field current passing through a field winding (50). A voltage booting converter (120) converts output voltage of a battery (B) and outputs the voltage between a power source line (107) and a grounding line (105). Field winding (50) is electrically connected onto an electric current channel between battery (B) and power source line (107) and formed so that voltage switched by a switching element (Q1) is applied to both ends. A controller (100) controls the field current so as to adjust density of magnetic flux between a rotor and a stator by performing switching control on switching element (Q1) and a switching element (Q3) connected in parallel to field winding (50) and converts the output voltage of battery (B) into voltage in accordance with a voltage command value.

摘要： A motor/alternator is formed by a single toroidal magnet and flux conductors which, in combination with flux switches, create an alternating magnetic circuit around a power coil. The motor/alternator geometry minimizes flux leakage. The form of the flux conductor and flux switch terminations allows for a high number of poles and reduces magnetic reluctance.

摘要： Claw-shaped magnetic poles are alternately disposed along the rotation plane of a rotor of an electric rotating machine, and a permanent magnet is disposed between the claw-shaped magnetic poles. Surface of the permanent magnet is coated with a coating layer. The coating layer is composed of a anticorrosive material performing sacrificial anticorrosion (metal flake in a coating film rusts prior to a matrix resulting in protection of the matrix) such as inorganic material containing zinc and a film of the anticorrosive material is formed by spraying. Ionization tendency of zinc is larger than that of iron composing the permanent magnet, and the permanent magnet is difficult to be rusted owing to the sacrificial anticorrosion. Consequently, anticorrosion of the permanent magnet disposed between the claw-shaped magnetic poles is improved.

摘要： A motor generator is provided with a stator having a winding around each of a plurality of stator teeth, and a rotor having a plurality of permanent magnets by the number larger than that of the stator teeth, arranged in the circumferential direction at equal intervals. The stator teeth are formed of a first stator teeth section including a plurality of stator teeth groups I, II, and III each including the adjacent stator teeth around which a winding to which the same phase voltage is applied is wound and in which winding directions of the stator teeth are opposite to each other, and a second stator teeth section including a stator teeth having a winding wound therearound and being placed among stator teeth groups of different phases such that electric power is independently input and output with respect to the first and second winding sections. This makes it possible to reduce the space and the cost while inputting/outputting the electric power through different channels and allowing arbitrary design of the electric power distribution.

摘要： A radial gap brushless electric machine (30) having a stator (31) and a rotor (32) and a primary air gap (34) also has at least one stationary excitation coil (35a, 36a) separated from the rotor (32) by a secondary air gap (37a, 37b) so as to induce a secondary flux in the rotor (32) which controls a resultant flux in the main air gap (34). Permanent magnetic (PM) material (38) is disposed in spaces between the rotor poles (A-H) to inhibit the secondary flux from leaking from said pole portions (A-H) prior to reaching the main air gap (34). By selecting the direction of current in the stationary excitation coil (35a, 36a) both flux enhancement and flux weakening are provided for the main air gap (34). A method of non-diffused flux enhancement and flux weakening for the machine is also disclosed.
