Abstract: PURPOSE:To ensure a simple inspection for the accuracy of the oscillation frequency in case the fundamental frequency component cannot be obtained, by installing the transmitting device synchronized with the reference frequency component pluse the frequency comparing device of a simple structure. CONSTITUTION:When a connection is secured between the terminals 1 and 2 via the switch SW1, the signal of reference frequency f0 is supplied to the oscillating device OSC1. Thus the device OSC1 is put under the slave state in synchronization with the frequency f0 and has an oscillation with the frequency f1. When the switch SW2 is turned off, the oscillating device OSC2 to which no frequency f0 is supplied is put under the free-run state and then has an oscillation with the frequency f2. The comparing device CMP compares the signal of f1 with the signal of f2. When the inspection of the unit OSC2 is over, the switch SW2 is turned on to give a slave working to the device OSC2. Then one of these two oscillating devices is set at the ACT side with the other set at the STAND-BY side each, thus obtaining the working of a double system.

IPC: H02K9/18
Filed: 1982-08-16
Abstract: PURPOSE:To contrive to miniaturize a bearing bracket and rotary shaft by such an arrangement wherein the diameter of a stator frame is reduced by composing a ventilation passage way rationally. CONSTITUTION:A ventilation gap 16a is interconnected to the ventilation route 9 of a stator frame ventilation portion 7a through an interconnected ventilation route 18 which pierces through the foot portion 7g and the bottom plate 7h of the stator frame, and further, the interconnected ventilation route 18, at the side of the bottom plate 7h of the stator frame, is opened into an air cooler 10 at a position located outward the foot portion 7g of the stator frame. With this, cooling wind flowing through the ventilation gap 16a reaches the ventilation route 9 passing through the interconnected ventilation route 18, therefore it becomes unnecessary to provide a ventilating hole in the stator frame bottom plate 7h at a position between a stator core 6 and the stator frame leg portion 7g, and such a space for a ventilating hole which has so far been necessary for a conventional device is no longer required. Due to this structure, the stator frame 7 becomes smaller, and in connection with this, a bearing bracket 11 also becomes smaller in diameter.
