    摘要： A two-phase unipolar driving brushless DC motor of a radial gap type having a rotor position detector includes a main-pole yoke having main-poles, an interpole yoke coaxially provided with the main-pole yoke in a superposed manner and having interpoles and an axial short-circuit portion or member provided in an axially extending portion in magnetic fluxes formed in the main-poles and interpoles. This structure allows for easy winding of coils around the main-poles and enhanced winding space factor in order to increase the starting torque and to improve the motor efficiency.

    摘要： A DC electric machine interpole disposed between adjacent main field poles is magnetically isolated from the machine frame and is characterized in that the pole piece or pieces which conduct interpole flux from the interpole into the armature is (are) longitudinally displaced and circumferentially adjacent to the pole piece or pieces which conduct interpole flux from the armature to the interpole. The longitudinal displacement of the sending and receiving pole pieces permits the circumferential width of the interpole to be relatively small thereby reducing flux leakage from main field pole to main field pole to effect an improvement in the performance of the machine.

    摘要： In a rotating machine, for example heteropolar, auxiliary poles (14) are placed in practically the field poles (4) and close to the peripheral of a salient section (.delta.) of rotor (2), the same azimuth symmetry plane as the poles are supplied by a current (i) regulated by a power supply and auxiliary regulation device (16), the armature current (I) and rotation speed (N) of the rotor expose armature conductors (8) in commutation to an equalizing flux providing for arc-free commutation. Auxiliary poles can be supplied with a current regulated by the field current to cancel the currents flowing in the armature conductors on the field poles. These machines, for example also acyclic with voltage step-up, have high specific power and efficiency, and can be employed for example, in electric traction or propulsion.

    摘要： The performance and commutating ability of a dynamoelectric machine using commutating poles are improved during transient loading conditions and during pulsations in the power supply of the machine through the use of transient flux barriers which are mounted between the commutating pole piece and the commutating winding of the machine. Because the transient flux barriers are manufactured out of metallic material having a high level of conductance, transient leakage flux from the commutating pole induces eddy currents in the transient flux barrier. As a result, these eddy currents are prevented from being generated in the frame of the machine itself resulting in improved commutation while the current of the machine is undulating. The transient flux barriers have an extension at the end thereof adjacent the armature so as to have a substantially L-shaped cross section, and both the barriers and the commutating coil are positioned as close to the armature as is reasonably possible.
