摘要：PURPOSE:To prevent the application of excessive force to a power transmission mechanism in the course of starting by passing a rotating speed corresponding to a twisting intrinsic oscillation at the time of starting a synchronous motor, interrupting a power source at the rotating speed exceeding...
PURPOSE: To obtain a method for synchronized starting of a synchronous motor by using a turbine generator when the generator has a capacity similar to the synchronous motor and is located closely to the motor. ;CONSTITUTION: A circuit breaker 12 is opened, a synchronous motor 2 is excited whil...
Starting device for a synchronous motor In the structure of the rotary member (3) fixing a windmill, propeller, fan, impeller and so forth on the rotary axis (1) of the motor (2), having a tubular boss (8) located at the center of the rotary member (3), having a bracket (6) th...
PURPOSE:Operation is started at a lower constant current than a rated current until a desired rotational speed is reached, a starting loss is prevented by changing it to constant current control at about rated current when the rotation is over the desired value, and thereby a generation of the...
synchronous motor. (b)A400V,50Hz,3phase,37.5kW,Y-connected synchronous motor has a full-load efficiency of88%andZs=0.2+j1.6Ωper phase. If the excitation of the motor is adjusted to give a leading power factor of0.9,c...
In a return stop for a self-starting synchronous motor (1) having an inert mass (9) which is arranged coaxially with a shaft (6) operatively connected to the motor, is rotatable with respect to the shaft, is positioned on the shaft in axial direction and is coupled to the shaft via a...
