Normally there are six terminals (two terminals per winding in 3 phase system) for a motor. If you find 12 terminals, you need to read the motor name details or specifications to get more info. The motor could be with two different sets of winding (double speed motor)

How can you terminate a 3 wire wye motor to a 3 phase delta connection?
To terminate a 3 wire wye motor to a 3 phase delta connection you need a 3 phase transformer to convert from delta to wye. Do not lift the common neutral connections inside the motor and rewire for delta, because the voltages will be wrong.
What is the reason motor runs delta connection?
Motor run delta connection because in delta connection it is less ampere needed and it sometimes it change the wye connection because of the available suply
How will the speed and the slip of the motor change with increasing load in star wye and delta connection?
the speed decrease if increasing load..in star connection the speed lower
Is a three phase high leg delta better than a wye for a motor?
There is really no advantage, the only purpose of having the variety is for motor manufacturer companies to be able to sell their product to customers if the building's electrical service is of a Delta of Wye configuration.
What is wye-delta motor control?
It is a type of starter that allows a motor to be started across the line by starting the motor with a reduced inrush current. The motor is started in a wye configuration until it gets up to speed and then a timer drops the wye contactor out a draws the delta configured contactor in. The motor then operates in a delta wired configuration.

Power a 415volt motor with 480volts?
in low voltage connection in wye (star conncetion) 415v high voltage connection in delta 480v

How do you connect Wye connection to open delta connection?
Dont mess with transformers if u dont know how to read a wiring diagram It is easy if u know your relation to each of the phases and neutral and ground

What is the difference between a phase to ground connection and a grounded wye connection?
A 'grounded-wye' connection describes a wye-connected supply, whose star-point (or common point) is grounded. This is essential in order to ensure stable phase voltages. I'm not sure what you mean by a 'grounded-phase' connection; if you mean a 'grounded-line' connection, then this is a short-circuit to ground from a line conductor.
How can you how can you detect wye from delta with neutral connections?
The star connection has three phase terminal leads and one neutral lead. In case of delta connection it has got three phase terminal leads. the star connection is generally represented by Mercedes symbol with neutral line drawn from the mid point. The delta is represented like a triangle symbol with noneutral line shown.
What is wye?
A wye is any object shaped similar to a letter Y, especially a Y-shaped connection of three sections of road or railroad track.
What is the difference between an open delta and an open wye connection?
An open delta connection is a delta connection with one phase removed, but still supplied with three line conductors. An open wye is a wye connection with one phase removed, supplying a three line conductors and a neutral conductor. An open-delta/open-wye is a method of providing a reduced-load three-phase supply using just two single-phase transformers, rather than the preferred method of using three single-phase transformers.
What size of electric motor that requires wye delta starter?
10 hp and above motor power rating....
