A motor having a speed directly proportional to the frequency of the alternating-current power that operates it. American Heritage® Dictionary of the English Language, Fifth ...
aWhen the large capacity synchronous motor starting, the rated current of the electric machine can reach four to seven times the impulse current generator, power distribution line loss, the loss of power transformer, the voltage generated in the reactor, such as electric elements as a result of...
DRIVE UNIT FOR SENSORLESS SYNCHRONOUS MOTOR PROBLEM TO BE SOLVED: To provide a drive unit capable of detecting step-out in any state such as high speed, large current, regenerative mode or stop condition. U Hidefumi,上田 英史 被引量: 0发表: 2005年 Accurate Detection for Initial Rotor Positio...
In this example, the field current (idf) and a gain block (R_start) are used to implement the resistance connected across the field winding. This model illustrates the starting procedure of a 60-kVA 400-V 50Hz synchronous motor. The motor is started at no load by closing the circuit ...
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...

In the case of a small synchronous motor in place of the alternator, it is not necessary to go through the elaborate synchronization procedure for alternators. However, the synchronous motor is not self-starting and must still be brought up to the approximate alternator electrical speed before it...
Electric motor - Synchronous, Rotating Fields, AC Motors: A synchronous motor is one in which the rotor normally rotates at the same speed as the revolving field in the machine. The stator is similar to that of an induction machine consisting of a cylind
