摘要： The portion to be deformed of a metal sheet is heated by irradiating it with a laser beam which is scanned at a high speed, and, when the portion to be deformed has attained a predetermined temperature, a bending force is applied to the portion to be bent to perform bending of the metal sheet. When the shape of a metal sheet is to be worked into a circular arc of 90.degree. having a predetermined radius by means of six bending processes, the metal sheet is worked such that the working process is divided into six processes and the bending processes are sequentially performed after fixing a metal sheet edge of the metal sheet. The yield strength of a steel material is reduced when it is heated and a metal sheet is worked using a laser by which a local heating is possible. Dies are therfore unnecessary, whereby processing at low costs and an apparatus therefor may be achieved.

摘要： An induction motor is controlled using a control device having a current control loop by detecting a current of the induction motor, and by detecting a current error corresponding to a difference between the detected current of the motor and a current command signal of the control device. The current error is processed to obtain a slip frequency. A field speed control command is generated based on the slip frequency and a motor speed of the induction motor.

摘要： Prioritizing one-way rotation and one-way torque in particular, a change is induced in the partial shape of a magnetic poles on the rotor of a reluctance motor in the direction of forward movement, or magnetic resistance is increased, the torque generation range of each phase is expanded, and the increase/decrease time of an electric current is ensured to reduce the noise. With the relative increase in copper losses due to this drive method, and harmful effects from the problem of an overvoltage generated in the full-pitch windings are reduced by a drive method in which the overvoltage is cancelled out.

摘要： An AC motor is provided. In the AC motor, there are M pieces (M is an integer of 3 or more) of stator pole groups SPG are arranged in a rotor axis direction, where each of the stator poles groups is composed of a plurality of stator poles which are for the same phase and arranged in a circumferential direction of the motor. Between the stator pole groups SPG, “M−1” pieces of annular windings WR are arranged which allow one-way current to flow therethrough. The windings WR are arranged such that the directions of current passing therethrough are reversed in turn in the rotor axis direction. The stator pole groups SPG are excited to generate magnetic fluxes φG directed in a one way. The excited directions of the magnetic fluxes φG are reversed in turn in the rotor axis direction.

摘要： A brushless AC motor has a rotor, N stator pole group, and plural loop-configuration stator windings. The rotor has magnetic poles with alternating N poles and S poles circumferentially disposed at equal interval. The stator has plural stator poles divided to N stator pole groups. Each group is formed circumferentially on the stator with each of adjacent pairs of the groups mutually differing in circumferential position by a desired amount. The stator windings are formed circumferentially on the stator, with each winding disposed immediately adjacent to a corresponding one of the stator pole groups, with respect to a rotor axis direction. As an example, the stator pole has an approximate parallelogram shape in which a top side and a base side of the stator pole in axis direction of the stator has an approximately same width in rotational direction, and the positions of the top side and the base side is shifted in rotational direction to each other.

摘要： A brushless motor and a related control device are disclosed in a structure wherein a stator has U-phase, V-phase and W-phase stator poles, with two of the U-phase V-phase and W-phase stator poles carry thereon respective phase windings, in the absence of a selected phase winding related to a remaining one of the U-phase V-phase and W-phase stator poles. The respective phase windings have end portions connected together at a junction point. A three-phase alternating voltage is applied to the respective phase windings and the junction point to allow the stator to have an electromagnetic action thereby drivably rotating a rotor. The stator poles may be formed in trapezoid shapes to minimize interference between associated component parts for easy assembly in high productivity and efficiency with a reduction in torque ripple.

摘要： An A-phase brushless motor, where A is an integer greater than or equal to 2, includes a stator and a rotor. The stator has q stator poles, where q is an integer greater than or equal to A. The stator poles form S stator pole sets each consisting of A stator poles each of which corresponds to one of A phases, where S is an integer equal to (q/A). The rotor has p rotor poles, where p is an integer greater than or equal to 2, and is so arranged that the rotor poles face the stator poles. Further, in the brushless motor, p≧q, and the stator poles are arranged in a circumferential direction of the motor such that a difference in electrical angular position between any adjacent two of the A stator poles in each of the S stator pole sets is equal to (360°/A).
