摘要： PROBLEM TO BE SOLVED: To provide a breakage detection device capable of detecting a breakage and/or wear of a support structure such as a support rotatably supporting an armature shaft of a motor by using a velocity electric generator.SOLUTION: When an inclination of an armature shaft gets larger due to a breakage or wear of a ball bearing or a roller bearing supporting the armature shaft, the distance between an inductor and a core constituting a velocity electric generator of a motor gets larger and also the output voltage output from a coil wound on the core gets smaller. In a BPG 9, even when the output of square wave (a), which is an output from a velocity electric generator of a motor, a speed comparison section 96 checks for a point of a square wave (b), which is an output from the velocity electric generator on a drive shaft to determine if there is any breakage or wear on the ball bearing 22 and the roller bearing 23. With this, any breakage or wear on the ball bearing 22 and roller bearing 23 can be reliably detected.

摘要： PROBLEM TO BE SOLVED: To obtain a blower for driving a PMSM through an inverter in which the blower is not protected but operation thereof is sustained, even under conditions where power supply is interrupted, and transition can be made quickly and surely to steady operation at the time of power restoration. SOLUTION: Under power failure state, voltage Vdc of a filter capacitor 2 is detected by a voltage detector 11 and delivered to a DC voltage control section 13, and then a Q-axis current command is calculated, such that the DC current command matches the detection value. A D-axis current command has a predetermined value. A coordinate converter 21 converts a three-phase current value into the DQ-axis current value. The D-axis current command and the D-axis current are inputted to a current controller 15, together with the Q-axis current command and the Q-axis current, and a DQ-axis output voltage command is operated. An axial deviation correcting section 22 receives a D-axis voltage command and outputs a correction amount of inverter output frequency, such that it becomes zero. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an eddy current braking system for vehicle which is compact and improves braking performance.
SOLUTION: The braking system comprises slot inserting portions in which a coil is inserted into slots of an iron core, and coil end portions extended in an axial direction from an end face of the iron core other than the slot inserting portions. The slot inserting portions and the coil end portions are constituted by a square conductor of which cross section is rectangular, and the slot inserting portions are arranged so that a cross-sectional longitudinal dimensional portion of the square conductor may become parallel to bottom faces of the slots. The coil end portions change a direction of the square conductor 90 degrees at a proximity portion to the slots. Dislocation forming portions are formed which causes the cross-sectional longitudinal dimensional portion to coincide with a depth direction of the slots, and lowered stepped portions are formed at middle positions of the dislocation forming portions adjoining each other so that a height position may dislocate in a vertical direction.
