摘要： A linear induction motor for an elevator which includes a secondary, stationary element having a body formed with a plurality of iron-core mounting holes arranged longitudinally of the body at a certain interval, and iron cores disposed in the holes. The stationary, secondary element allows magnetic flux flowing therethrough to pass through the iron cores, thereby reducing the dimension of the total magnetic gap in the motor. Furthermore, the combination of the iron cores in which eddy currents flow with difficulty and the body along which eddy currents tend to flow makes it possible to reduce the ineffective eddy currents.

The apparatus includes a rectifying circuit connected to the AC source, a resistor connected between the rectifying circuit and the smoothing capacitor, a charging time measuring circuit for measuring the time from turn-on of the AC source until the completion of charging the smoothing capacitor, and a control circuit for producing an abnormality detection signal when it is detected that the output of the charging time measuring circuit is shorter than a predetermined value, whereby the reduction in capacitance of the capacitor, and hence the expiration of the lifetime of the same, can be evaluated in advance.
