摘要： An object of the present invention is to provide a compact, high-power rotating electric machine by downsizing coil ends on a distributed-wound stator using rectangular wires in comparison with the conventional one or by enhancing coil heat radiation from the coil ends or slot insertion portions.A stator (110) comprises a stator core (112), and stator coils (114) inserted into stator slots (112S) formed between a plurality of stator teeth (112T) formed on the stator core, and wound around the stator teeth in the form of distributed winding. Each stator coil (114) includes a plurality of rectangular wires having insulating coating, and the plurality of rectangular wires are inserted into the one stator slot. The direction of arrangement of the plurality of rectangular wires in the stator slot is different from that of the plurality of rectangular wires at both coil ends outside the stator slot.

摘要： A permanent magnet rotating electric machine uses no skewing under a predetermined current and voltage condition to prevent torque from decreasing and to decrease pulsation torque to make the machine less vibrating and less noisy. The permanent magnet rotating electric machine includes a stator with multi-phase stator windings and a rotor with a plurality of permanent magnets internally embedded in a rotor core. The core shape of the rotor is uniform in the depth (longitudinal) direction with no skewing in the arrangement of the permanent magnets. The permanent magnets are symmetrical with respect to the rotation direction, but irregular with respect to the depth direction, for each pole. A magnetic flux generated from the between-pole permanent magnets almost equals a magnetic flux generated from the pole-center permanent magnet.

摘要： A permanent magnet type rotating electrical machine that is capable of producing a higher output and is suitable for high-speed rotation. A pair of nonmagnetic portions are formed in a rotor core at opposite ends of each pole. The waveform of induced voltage and a motor voltage are adjusted based on two parameters, i.e., an angle covering minimum magnetic path portions formed by the nonmagnetic portions and a magnet width. Assuming that a circumferential pitch of teeth cores with respect to a rotor axis is τs (degree) and an opening angle contained by a circumferential width between radial width minimum points of the pair of magnetic path portions with respect to the rotor axis is θ (degree), θ≈(n+Y)×τs (n: integer larger than 0) is met. Y=0.5 is set when the stator windings are wound in a distributed winding way, and Y=0.9-1.2 is set when they are wound in a concentrated winding way. The magnet forming one pole is divided into two parts, and a bridge portion is formed between the two divided magnet parts.
