A transient stability analysis on starting a 20 000 hp synchronous motor is presented. An application analysis should consider mutually interacting characteristics of the motor, load and the power supply system.Jagdish C.DasProcess control, electrical & information conference ISA-PUPID 38th annual ...
A synchronous motor is not a self-starting motor because torque is only developed when running at synchronous speed; therefore, the motor needs some type of device to bring the rotor to synchronous speed.Synchronous motors use a wound rotor. This type of rotor contains coils of wire placed in...
The new type of a hydraulic exciter of angular mechanical systems vibrations has been studied. Its principle of operation is based on a loss of stability i... VK Astashev,AN Tresvyatskij 被引量: 23发表: 1993年 Some comments on the experimental determination of modal densities and loss facto...

aAsynchronous motor, synchronous motor, stepping motor, stator winding to distinguish between synchronous and asynchronous motor servo motor is the same, the main difference is that the rotor structure. A synchronous motor rotor DC excitation winding, so they through the introduction of external excitat...
The magnetic geared motor (MGM) is a system in which a magnetic gear and a permanent magnet synchronous motor (PMSM) are mechanically combined, and it consists of a dual rotor that rotates at different speeds. Due to these characteristics, it has the advantages of high-power density and ...
We investigated the torque characteristics and the motor efficiency of interior permanent magnet synchronous motors (IPMSM), in which a rotor core consists of high-strength nonoriented electrical steel, as-cold-rolled nonoriented electrical steel, and conventional nonoriented electrical steel with various...
Many of the existing control methods for the permanent magnet synchronous motor (PMSM) either deal with steady state models or consider dynamic models under particular cases. A dynamic model of the PM machine allows powerful control-theoretic techniques such as linearization to be applied to the ...
