摘要： PROBLEM TO BE SOLVED: To make it possible to apply heat to fluid without use of a special heating means, such as a heater, when a fan is rotated to cause fluid to flow, and obtain a motor device that makes it possible to enhance the performance of applying heat to fluid and shorten the time required to apply heat. SOLUTION: When a motor 2 is being driven, a heating control unit 18 computes amounts of correction ΔV* and Δi* to make loss in the motor 2 and an inverter device 1 equal to or larger than a predetermined value. This computation is carried out based on a rotational speed command value ω*, an output voltage command value Vo* computed by an output voltage computation unit 15, the driving currents Iu, Iv and Iw for the motor 2, and the temperature Tm of the motor. When the output voltage computation unit 15 computes the output voltage command value Vo* for driving the motor 2 at a rotational speed corresponding to the rotational speed command value ω* based on the rotational speed command value ω* and the driving currents Iu, Iv, and Iw for the motor 2, it takes in the above-mentioned amounts of correction computed by the heating control unit 18.

摘要： PROBLEM TO BE SOLVED: To keep the dimensional accuracy and suppress the influence of unwanted resin attaching to a rotor shaft, by providing a rotor with at least either a plastic shrinkage preventing means for a bearing support section included in the rotor, or a resin suppressing means which eliminates the necessity of suppression of resin to be attached to the rotor shaft at the time of shaping. SOLUTION: Shrinkage of a plastic magnet rotor after shaping appears in the entire plastic magnet and therefore plastic magnet covering bearing support sections 2A at both ends of a rotor shaft 1, and the rotor shaft 1 between them also shrinks. In the bearing support sections 2A and the rotor shaft 1 between them, plastic magnet shrinks both inwards in the diametric direction of the rotor and in the axial direction of the rotor shaft 1. Therefore, in the bearing support sections 2A, force for the sections 2A to be pulled is caused due to the shrinkage of plastic magnet on the inner side. This force, however, is received and absorbed by recessed sections 7 formed in the bearing support sections 2A due to the expansion of the recessed sections 7. By this method, the influence of the shrinkage of plastic magnet can be prevented and thereby the dimensional accuracy can be maintained.
摘要翻译：要解决的问题：为了保持尺寸精度并且抑制不希望的树脂附着到转子轴的影响，通过为转子提供至少一个用于包括在转子中的轴承支撑部分的塑性收缩防止装置或抑制树脂的树脂在成型时不需要抑制要连接到转子轴上的树脂的装置。解决方案：成型后的塑料磁体转子的收缩出现在整个塑料磁体中，因此在转子轴1的两端处的塑料磁体覆盖轴承支撑部分2A，并且它们之间的转子轴1也收缩。在它们之间的轴承支撑部分2A和转子轴1之间，塑料磁体在转子的直径方向和转子轴1的轴向上都向内收缩。因此，在轴承支撑部分2A中，由于内侧的塑料磁体的收缩导致被拉动的2A被引起。然而，该力由于凹部7的膨胀而形成在轴承支撑部2A中的凹部7被吸收和吸收。通过这种方法，可以防止塑料磁体的收缩的影响，从而可以确保尺寸精度可以维护。

摘要： PROBLEM TO BE SOLVED: To solve the problem that generated magnetic flux must cross over a slit, flow of the magnetic flux is deteriorated, loss is increased and efficiency is decreased by a rotating position of a rotor, because a slit form of the conventional rotor is set to be symmetric to a q-axis which is the direction along which the magnetic is flux hard to flow. SOLUTION: At least a pair of slit parts is installed which is arranged in the rotor and forms a magnetic pole protrusion so as to obtain a d-axis and the q-axis. The d-axis is a direction along which the magnetic flux is easy to flow, and the q-axis is a direction along which the magnetic flux is hard to flow. Small reluctance parts where reluctance is small are disposed in the slit parts, thereby making the slit parts asymmetric to the q-axis. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To structurally ensure fixing strength for magnets in the direction of revolution and in the axial direction, and further to enhance the concentricity between the magnets and a back yoke. SOLUTION: Whirl-stop recesses which extend from the one-side end of the back yoke in the axial direction to a midpoint in the axial direction are formed in the circumferential surface of the back yoke in the axial direction. Whirl-stop projections are formed on the inner circumferential surface of the ring-shaped magnet of a rotor in the axial direction. The whirl-stop projections are fit into the whirl-stop recesses to cause the projections and the recesses to function as a whirl-stop in the direction of revolution and further as a coming-off stopper for preventing the ring-shaped magnet of the rotor from coming-off to the other-side end in the axial direction. Further, coming-off preventing members which function to prevent the ring-shaped magnet of the rotor from coming-off to the one-side end in the axial direction. In addition, clearance adjusting projections for adjusting and uniformizing the clearance between the magnet and the back yoke are formed on the inner circumferential surface of the ring-shaped magnet of the rotor.

摘要： PROBLEM TO BE SOLVED: To provide a rotor of a permanent-magnet motor and a manufacturing method therefor, wherein the driving characteristic during operation is improved and reduction of noise and vibration is implemented at relatively low cost, while maintaining high efficiency. SOLUTION: A rotor core is formed by laminating one type of stamped plates for rotor core. The stamped plates for rotor core have in the circumferential direction a plurality of permanent magnet embedding holes for embedding permanent magnets in proximity of the periphery thereof. The permanent magnet embedding holes are positioned so that their center is off the polar center. After a specified number of the stamped plates for rotor core have been laminated, the remaining plates are turned upside down and are laminated, so that the respective permanent magnet embedding holes overlap. Thus individual permanent magnets are slanted in the circumferential direction and embedded into the individual permanent magnet embedding holes which are formed so that each of the holes extends in the axial direction and goes off the center axis along the way.

摘要： PROBLEM TO BE SOLVED: To provide a permanent magnet rotating electric machine which can improve the drive characteristics at start and running, reduce demagnetization of the permanent magnets, widen the running range, improve the efficiency, and reduce the noise. SOLUTION: In a permanent magnet rotating electric machine having permanent magnets buried inside the rotor core, the permanent magnets are built in so that their positions can be changed. Thus, by changing the position of the magnets depending on the running conditions, the motor constants are controlled. The permanent magnets are made movable inside the rotor.
