摘要： PROBLEM TO BE SOLVED: To improve the efficiency of an electric motor having a split core.
SOLUTION: A core 20 split with a foundation portion 32 split and an erect portion 34 are fastened with bolts 36. This brings a joint surface 46 of the foundation portion 32 to the erect portion 34 into close contact with each other, thus reducing magnetic resistance and improving efficiency. The bolt 36, made of non-magnetic material, reduces the number of magnetic fluxes passing through the bolt, thus reducing an eddy current developed in the bolt. Moreover, a ratio (H/D) of a distance H between a teeth front end face 48 and a bolt head top face 50 to a diameter D of a bolt hole is set at ≤0.3.

摘要： PROBLEM TO BE SOLVED: To detect a load current from the on-voltage of an inverter main circuit element. SOLUTION: A voltage (the on-voltage), when a switching element Q or a diode D is in conduction state in the main circuit elements 18U-2, 18V-2, and 18W-2 of the lower side arm of the inverter 12, is detected by voltmeters 16U, 16V, and 16W.

摘要： PROBLEM TO BE SOLVED: To provide a motor drive system wherein torque ripples can be made smaller in rectangular wave control. SOLUTION: The motor driven system comprises an inverter which receives input from a high-voltage direct-current power supply, and converts it into a predetermined alternating current and outputs it; a motor which is driven by the output of the inverter; a low-voltage direct-current power supply connected with the neutral point of the motor; and a controller which controls the operation of the inverter. The controller controls the operation of the inverter with a predetermined rectangular wave and inserts breaks constituted of output inverted sections of predetermined width into the rectangular wave. At the same time, the controller varies the position of insertion of the breaks, according to the ratio of the voltage of the high-voltage direct-current power supply to that of the low-voltage direct-current power supply. A break, constituted of a section of a 0 voltage of a rectangular wave is chopped, when the inverter is driven with the rectangular wave. By having the position α and the width β of this break optimized, torque ripples are suppressed. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To reduce loss in an inverter system. SOLUTION: A DC power source is arranged between the neutral point of the star-connected coil of a motor M2 and the negative side DC line of a second inverter INV2. The neutral point of the star-connected coil of a motor M1 is connected to the positive side DC line of the second inverter.

摘要： PROBLEM TO BE SOLVED: To reduce the loss due to an eddy current by reducing the eddy current generated in teeth in case that a core is composed of a plurality of core segments. SOLUTION: The stator core is composed of the plurality of core segments 32 segmentalized by the cleavage plane 30 at cleavage planes passing inside each tooth 24. The cleavage plane 30 segmentalizes a tooth 24 that it passes, in the direction of array of the tooth 24. The cross section orthogonal to the magnetic flux 36 of the tooth 24 is divided in the circumferential direction of the core by the cleavage plane 30, and the cross section of the tooth 24 where an eddy current 34 circulates decreases, so it can reduce the eddy current 34 generated in the tooth 24.

摘要： PROBLEM TO BE SOLVED: To efficiently cool a rotor of an axial permanent magnet motor, especially a permanent magnet.
SOLUTION: An air channel 36 where a fluid such as air flows is formed between permanent magnets 34 constituting the magnetic pole of a rotor 30. The air channel 36 is provided almost in the radial direction of the rotor 30, and the fluid in the channel flows under the action of a centrifugal force when the rotor rotates. Thus, cooling is carried out near the permanent magnet, which heats more, inside the rotor, and the generated heat is promptly exhausted, while the heat radiation area of the rotor increases for more efficient cooling.
