Title: Controller for synchronous motor
Inventor: NAKAMURA TOSHITAKA
IPC: H02P21/22
Filed: 1991-07-22
Abstract: PURPOSE:To conduct a safe operation without flux saturation by correcting a flux command, when the vector sum of a voltage reference exceeds a predetermined value. CONSTITUTION:A voltage-limiting means 20 operates V=(Vd<2>+Vg<2>)1/2 from the voltage reference values Vd and Cg of d-and g-axes and when V is compared with a voltage limiting value VLMT and V>VLMT, the voltage-limiting means integrates the difference by a proportional integral to output a flux compensating quantity phiC. A subtraction means 21 outputs a value obtained by the subtraction of the flux compensating quantity phiC from a flux command phiS as actual flux command value phi. At the time of a high load, the terminal voltage of a synchronous motor rises so that the flux compensating value phiC, at which the operated value V exceeds VCMT, rises and the flux command phi decreases. As a result, the terminal voltage is controlled to VLMT. When the flux command phidecreases, a current reference iT for torque increases by a current reference- computing element 7 so that the output of the synchronous motor does not change.

IPC: B65D47/08
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To costlessly provide a synthetic resin cap with a hinge whose cover can be easily opened or closed and it is not opened unnecessarily. SOLUTION: The side faces of a cover 2 are flexible and fixing parts are formed at both sides of the top plate 4 of the cap body 1 and both side faces 9 of the cover 2. The cover is locked when it is closed as respective fixing parts are connected to engage with each other and the side faces of the cover 2 are warped by pressing the front side face 8 of the cover 2 when opening it and the side faces 9 are widened and the fixing parts are disengaged and hence, the cover is unlocked. In this way, by only pressing the cover onto the top face 4, the cover can be not only closed but also locked and also the cover can be easily opened by pulling up the front side face while pressing it forward. And hence, bothersome manipulation to release the locking structure is not required and further, the cover 2 is not opened unnecessarily.
