Is there another way to reverse star delta motor other then swaping two phases over?

If the motor is connected to a VFD the conductors of the motor need not be changed. The phase reversal can be done with the VFD's internal circuitry.

Is there another way to reverse star delta then swap two phases?
Yes, you can change the diode configuration. a diode will only let electricity flow in one direction. See also Delta- Y, and whetstone bridge.
Theory for brake test on three phase induction motor?
why three phase induction motor is delta connected
How do you check to see if electric motor windings are delta or Y?
in a delta configuration the current is split between the phases, as opposed to a wye configuration where the current will be equal on all phases. and vice versa for voltage.
What is a forward-reverse star delta?
A forward reverse star delta is a two in one motor starter where a motor first runs on star connection and then changed to delta connection after a time which has been set. The motor direction can be changed, whether forward or reverse
Can you reverse the motor if it is running in star or delta?
YES!!!
What is Delta Delta Delta's motto?
The motto of Delta Delta Delta is 'love one another'.
What is the value of delta g at melting point?
At the melting point, the solid and liquid phases are in equilibrium so the value of delta G is zero.
Differentiate star to delta connection of a transformer?
Star has one red, one yellow, one blue and neutral phases seperatelly. Delta has all four in sequence, combined.
Is delta confiquation better than y?
In a Y configuration, all AC system loads are connected at the same one point and are typically unbalanced. A neutral cable is used where the three phases meet. The delta configuration uses three phases that are connected in a triangle without a neutral cable. The delta configuration is better when you need high voltage transmissions.
What is the reason if you are running an electric motor with a star delta starter but whenever it is switched to delta at the same instant its circuit breaker trips?
Check your Delta connections first if the phases is corresponding, and check your Circuit Breaker if it sufficiently rated.
What is the easiest method of reversing the direction of rotation of a 3 phase induction motor controlled by star-delta starter?
Just swap two of the phases over. <<>> Care must be taken when swapping wires on a star delta system. Reversing the wrong set in the motor box and getting the wrong wires could accidently reverse the wrong set of windings. This would cause the star magnetic to be rotating in the correct rotation and then when it switches to delta the motor tries to reverse causing a locked rotor condition and spiking the voltage very high and hopefully tripping the overload protection. The correct place to swap the two legs is at the supply side of the star contactor.
What is another word for floodplain?
