摘要： An improved trip device for operating a trip mechanism which, in turn, operates a circuit breaker mechanism for opening a set of electrical contacts. The trip device includes a spring-biased actuating rod which is mechanically operated by a solenoid. The actuating rod has a notched end which is secured by a rotatable shaft at a notch portion of the shaft. The shaft has latch arms, and the core of the solenoid has projections extending into slots in the latch arms. When the solenoid receives a faulty current signal, the core moves and causes the projections to forcibly impact against the latch arms which rotates the shaft, whereby the notch portion of the shaft aligns with the notched end of the actuating rod and the actuating rod reciprocally moves into the notched portion of the shaft thereby actuating the trip mechanism.

摘要： A brushless dynamoelectric machine with a molded insulating control wheel having a rim on whose inner surface the rectifiers and other components of the starting control circuitry are directly mounted. Proximate the central hub of the control wheel is mounted a resistor wheel of metal having axial apertures in which are located cartridge heater-type resistors that are interconnected to provide the starting resistor of the control circuitry. The resistor wheel has external fins that aid in dissipating heat from the resistors and also blow air onto the components mounted on the wheel rim.
