This video demonstrates how to make "Reverse Forward Motor Starter". This video covers both power wiring and control wiring along with testing at the end of video using motor run status. We have used 3-phase supply from the VFD output set at low frequency so that motor rotates slowly to check the direction of rotation. Hope this video serves both tutorial value along with practical approach.
We hope this video will be helpful to beginners, technicians and students who are new to automation and electrical systems.
Reverse forward DOL starter
As the name defines forward reverse starter is used to run
the motor in both sides forward and reverse. The figure given
below shows the control and power diagram of forward and
reverse starter diagram. These forward and reverse starters
are dol type and not used above the 05 HP motors.
DOL starter a dol starter is Direct On Line starter or across
the line starter is a method of starting of a 3 phase induction
motor. in dol starter an induction motor is connected directly
across its 3 phase supply and the dol starter applies the full
line voltage to the motor terminals.
How does DOL starter work
principle of Direct On Line Starter DOL to start
the connection is closed applying full line voltage to the motor
winding. the motor will draw a very high inrush current for a very
short time the magnetic field in the iron and then the current will
be limited to the Locked Rotor Current of the motor.
What is reverse forward?
A reverse/forward stock split is a stock split strategy used by
companies to eliminate shareholders that hold fewer than
a specified number of shares. A reverse/forward stock split uses
a reverse stock split followed by a forward stock split
