Figure 6– Star-delta starter curve – Synchronous speed / Full-load current Figure 6 – Star-delta starter curve – Synchronous speed / Full-load current Starting torque and current are considerably lower at star-delta starting than at direct-on-line starting: one third of the equivalent DOL...

at each phase at starting and hencecurrentis reduced. As soon as motor achieves certain speed, motor winding is connected in delta fashion such that line voltage is equal to phasevoltagewith the help of two way switch. The star delta starter is used for starting ofinduction motorabove 5 H....
This product can effectively limit the starting current of asynchronous motors and can be widely used in loads such as fans, water pumps, conveyors, and compressors. It is an ideal replacement for traditional reduced voltage starting devices such as star/delta conversion, autot...
Contactor assembly for star-delta (wye-delta) start The starting of a motor with a contactor assembly for star-delta start requires three contactors: star contactor, delta contactor and line contactor. With the star-delta start, the starting current is reduced to approximately 1/3 due to the ...

The paper comparatively introduces 2 kinds of electrical devises used in soft-start A.C motor with middle voltage:resistance and reactor,comparatively introduces 4 kinds of soft-starter :SCR,SR(saturable reactor),liquid with motive plate and liquid without motive plate. The paper also introduces the...
two or three phases of a three-phase induction motor so that the resistors or reactors are short-circuited after current is permitted to flow therethrough during the starting of the motor, or in which the connection of the winding of the motor is changed from star to delta. 电阻器或反应器...
