What Is a Wye Motor?
A Delta-Wye Transformer Is a Type of Three-Phase Electric Power Transformer Design That Employs Delta-Connected Windings on Its Primary and Wye/Star Connected...

Furthermore, what is the difference between Wye and Delta Motors?
Wye. The Delta configuration has the three phases connected like a triangle. Delta systems have four wires total: three hot wires and one ground wire. Wye systems utilize a star configuration, with all three hot wires connected at a single neutral point.
Furthermore, what is a wye system? A Wye (Y) configuration is when all the loads in an AC system are connected at a single point. Normally, the loads are unbalanced in a Y configuration. A neutral cable is connected at that centre point where the three phases meet.
In this way, are most motors Wye or Delta?
The reason is that in delta, full line voltage is applied to each winding in the motor and in wye, the windings only see phase voltage (root 3 less than delta) so for the same HP, more current is needed. Usually wye motors are more common for smaller sizes and I haven't seen many in larger applications.
What is the purpose of a wye start and Delta run?
Wye Start Delta Run This method is actually reduced voltage but is accomplished by changing the motor phase connections such that a winding that is designed to run with phase voltage equal to line voltage on delta connection is wye connected for starting to put less than line voltage on each phase.
