PURPOSE:To reduce the capacity of a starter, by branching one or two of a plurality of synchronous motor armature winding parallel circuits and supplying starting power from a semiconductor power rectifier. CONSTITUTION:The armature winding parallel circuit of the synchronous motor 5 is divided into ...

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...
SUBSTANCE: increase of asynchronous moment under condition of start is achieved thanks to optimum control over excitation as function of electromagnetic torque. In this case acceleration of motor with the aid of starting resistor takes place in interval of change of sliding up to first preset value...

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 breaker at t=0.1s. A 2 pu resistor is initially connected across the field winding. When the rotor speed reaches 0.99 pu, the "R_start" resisto...

A starting system for a synchronous motor has a radial drive arm (10) and a radial running arm (14) on the same motor shaft (12). The drive arm is designed to block against the surrounding housing (30) of the motor rotates in the wrong direction thereby causing the control to restart...
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...
